Basic support for esp8266 platform

Browse Source 
This includes empty stubs for most core Arduino functions.
Need to actually implement all those digital reads writes whatever.
Need to prebuild toolchains (xtensa-elf-lx106) for 3 platforms and put them on some download server.
Need to do the same with esptool.
Need to fix 0x40000 binary generation and add correct upload commands.
Maybe even implement uploads over WiFi.

Arduino
========
* Arduino is an open-source physical computing platform based on a simple i/o
board and a development environment that implements the Processing/Wiring
language. Arduino can be used to develop stand-alone interactive objects or
can be connected to software on your computer (e.g. Flash, Processing, MaxMSP).
The boards can be assembled by hand or purchased preassembled; the open-source
IDE can be downloaded for free.
* For more information, see the website at: http://www.arduino.cc/
or the forums at: http://arduino.cc/forum/
* To report a *bug* in the software or to request *a simple enhancement* go to:
http://github.com/arduino/Arduino/issues
* More complex requests and technical discussion should go on the Arduino Developers
mailing list:
https://groups.google.com/a/arduino.cc/forum/#!forum/developers
* If you're interested in modifying or extending the Arduino software, we strongly
suggest discussing your ideas on the Developers mailing list *before* starting
to work on them. That way you can coordinate with the Arduino Team and others,
giving your work a higher chance of being integrated into the official release
https://groups.google.com/a/arduino.cc/forum/#!forum/developers
Installation
------------
Detailed instructions are in reference/Guide_Windows.html and
reference/Guide_MacOSX.html. For Linux, see the Arduino playground:
http://www.arduino.cc/playground/Learning/Linux
Credits
--------
Arduino is an open source project, supported by many.
The Arduino team is composed of Massimo Banzi, David Cuartielles, Tom Igoe,
Gianluca Martino, Daniela Antonietti, and David A. Mellis.
Arduino uses the [GNU avr-gcc toolchain](http://gcc.gnu.org/wiki/avr-gcc), [avrdude](http://www.nongnu.org/avrdude/), [avr-libc](http://www.nongnu.org/avr-libc/), and code from
[Processing](http://www.processing.org) and [Wiring](http://wiring.org.co).

/*
* Udp.cpp: Library to send/receive UDP packets.
*
* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
* aware of it. Again, this may not be a concern in practice on small local networks.
* For more information, see http://www.cafeaulait.org/course/week12/35.html

SD - a slightly more friendly wrapper for sdfatlib
This library aims to expose a subset of SD card functionality
in the form of a higher level "wrapper" object.
License: GNU General Public License V3
(Because sdfatlib is licensed with this.)
(C) Copyright 2010 SparkFun Electronics
This library provides four key benefits:
* Including `SD.h` automatically creates a global
`SD` object which can be interacted with in a similar
manner to other standard global objects like `Serial` and `Ethernet`.
* Boilerplate initialisation code is contained in one method named
`begin` and no further objects need to be created in order to access
the SD card.
* Calls to `open` can supply a full path name including parent
directories which simplifies interacting with files in subdirectories.
* Utility methods are provided to determine whether a file exists
and to create a directory heirarchy.
Note however that not all functionality provided by the underlying
sdfatlib library is exposed.
*/
/*
Implementation Notes
In order to handle multi-directory path traversal, functionality that
requires this ability is implemented as callback functions.
Individual methods call the `walkPath` function which performs the actual
directory traversal (swapping between two different directory/file handles
along the way) and at each level calls the supplied callback function.
Some types of functionality will take an action at each level (e.g. exists
or make directory) which others will only take an action at the bottom
level (e.g. open).

Parse individual path components from a path.
e.g. after repeated calls '/foo/bar/baz' will be split
into 'foo', 'bar', 'baz'.
This is similar to `strtok()` but copies the component into the
supplied buffer rather than modifying the original string.
`buffer` needs to be PATH_COMPONENT_BUFFER_LEN in size.
`p_offset` needs to point to an integer of the offset at
which the previous path component finished.
Returns `true` if more components remain.
Returns `false` if this is the last component.

When given a file path (and parent directory--normally root),

the supplied object for context if required.
e.g. given the path '/foo/bar/baz'
the callback would be called at the equivalent of
'/foo', '/foo/bar' and '/foo/bar/baz'.
The implementation swaps between two different directory/file
handles as it traverses the directories and does not use recursion
in an attempt to use memory efficiently.
If a callback wishes to stop the directory traversal it should
return false--in this case the function will stop the traversal,
tidy up and return false.
If a directory path doesn't exist at some point this function will
also return false and not subsequently call the callback.
If a directory path specified is complete, valid and the callback
did not indicate the traversal should be interrupted then this
function will return true.

\section Intro Introduction
The Arduino SdFat Library is a minimal implementation of FAT16 and FAT32
file systems on SD flash memory cards. Standard SD and high capacity
SDHC cards are supported.
The SdFat only supports short 8.3 names.
The main classes in SdFat are Sd2Card, SdVolume, and SdFile.
The Sd2Card class supports access to standard SD cards and SDHC cards. Most
applications will only need to call the Sd2Card::init() member function.
The SdVolume class supports FAT16 and FAT32 partitions. Most applications
will only need to call the SdVolume::init() member function.
The SdFile class provides file access functions such as open(), read(),
remove(), write(), close() and sync(). This class supports access to the root
directory and subdirectories.
A number of example are provided in the SdFat/examples folder. These were
developed to test SdFat and illustrate its use.
SdFat was developed for high speed data recording. SdFat was used to implement
an audio record/play class, WaveRP, for the Adafruit Wave Shield. This
application uses special Sd2Card calls to write to contiguous files in raw mode.
These functions reduce write latency so that audio can be recorded with the
small amount of RAM in the Arduino.
\section SDcard SD\SDHC Cards
Arduinos access SD cards using the cards SPI protocol. PCs, Macs, and
most consumer devices use the 4-bit parallel SD protocol. A card that
functions well on A PC or Mac may not work well on the Arduino.
Most cards have good SPI read performance but cards vary widely in SPI
write performance. Write performance is limited by how efficiently the
card manages internal erase/remapping operations. The Arduino cannot
optimize writes to reduce erase operations because of its limit RAM.
SanDisk cards generally have good write performance. They seem to have
more internal RAM buffering than other cards and therefore can limit
the number of flash erase operations that the Arduino forces due to its
limited RAM.
\section Hardware Hardware Configuration
SdFat was developed using an
<A HREF = "http://www.adafruit.com/"> Adafruit Industries</A>
<A HREF = "http://www.ladyada.net/make/waveshield/"> Wave Shield</A>.
The hardware interface to the SD card should not use a resistor based level
shifter. SdFat sets the SPI bus frequency to 8 MHz which results in signal
rise times that are too slow for the edge detectors in many newer SD card
controllers when resistor voltage dividers are used.
The 5 to 3.3 V level shifter for 5 V Arduinos should be IC based like the
74HC4050N based circuit shown in the file SdLevel.png. The Adafruit Wave Shield
uses a 74AHC125N. Gravitech sells SD and MicroSD Card Adapters based on the
74LCX245.
If you are using a resistor based level shifter and are having problems try
setting the SPI bus frequency to 4 MHz. This can be done by using
card.init(SPI_HALF_SPEED) to initialize the SD card.

\section SdFatClass SdFat Usage
SdFat uses a slightly restricted form of short names.
Only printable ASCII characters are supported. No characters with code point
values greater than 127 are allowed. Space is not allowed even though space
was allowed in the API of early versions of DOS.
Short names are limited to 8 characters followed by an optional period (.)
and extension of up to 3 characters. The characters may be any combination
of letters and digits. The following special characters are also allowed:
$ % ' - _ @ ~ ` ! ( ) { } ^ # &
Short names are always converted to upper case and their original case
value is lost.
\note
The Arduino Print class uses character
at a time writes so it was necessary to use a \link SdFile::sync() sync() \endlink
function to control when data is written to the SD card.
\par
An application which writes to a file using \link Print::print() print()\endlink,
\link Print::println() println() \endlink
or \link SdFile::write write() \endlink must call \link SdFile::sync() sync() \endlink
at the appropriate time to force data and directory information to be written
to the SD Card. Data and directory information are also written to the SD card
when \link SdFile::close() close() \endlink is called.
\par
Applications must use care calling \link SdFile::sync() sync() \endlink
since 2048 bytes of I/O is required to update file and
directory information. This includes writing the current data block, reading
the block that contains the directory entry for update, writing the directory
block back and reading back the current data block.
It is possible to open a file with two or more instances of SdFile. A file may
be corrupted if data is written to the file by more than one instance of SdFile.
\section HowTo How to format SD Cards as FAT Volumes
You should use a freshly formatted SD card for best performance. FAT
file systems become slower if many files have been created and deleted.
This is because the directory entry for a deleted file is marked as deleted,
but is not deleted. When a new file is created, these entries must be scanned
before creating the file, a flaw in the FAT design. Also files can become
fragmented which causes reads and writes to be slower.
Microsoft operating systems support removable media formatted with a
Master Boot Record, MBR, or formatted as a super floppy with a FAT Boot Sector
in block zero.
Microsoft operating systems expect MBR formatted removable media
to have only one partition. The first partition should be used.
Microsoft operating systems do not support partitioning SD flash cards.
If you erase an SD card with a program like KillDisk, Most versions of
Windows will format the card as a super floppy.
The best way to restore an SD card's format is to use SDFormatter
which can be downloaded from:
http://www.sdcard.org/consumers/formatter/
SDFormatter aligns flash erase boundaries with file
system structures which reduces write latency and file system overhead.
SDFormatter does not have an option for FAT type so it may format
small cards as FAT12.
After the MBR is restored by SDFormatter you may need to reformat small
cards that have been formatted FAT12 to force the volume type to be FAT16.
If you reformat the SD card with an OS utility, choose a cluster size that
will result in:
4084 < CountOfClusters && CountOfClusters < 65525
The volume will then be FAT16.
If you are formatting an SD card on OS X or Linux, be sure to use the first
partition. Format this partition with a cluster count in above range.
