5a033835e1 Add a build directory for libbearssl.a (#4736)
Simple git submodule and makefile for building the bearssl library
from source in the Arduino tree.

e3c970210f Add BearSSL client and server, support true bidir, lower memory, modern SSL (#4273)
BearSSL (https://www.bearssl.org) is a TLS(SSL) library written by
Thomas Pornin that is optimized for lower-memory embedded systems
like the ESP8266. It supports a wide variety of modern ciphers and
is unique in that it doesn't perform any memory allocations during
operation (which is the unfortunate bane of the current axTLS).

BearSSL is also absolutely focused on security and by default performs
all its security checks on x.509 certificates during the connection
phase (but if you want to be insecure and dangerous, that's possible
too).

While it does support unidirectional SSL buffers, like axTLS,
as implemented the ESP8266 wrappers only support bidirectional
buffers. These bidirectional buffers avoid deadlocks in protocols
which don't have well separated receive and transmit periods.

This patch adds several classes which allow connecting to TLS servers
using this library in almost the same way as axTLS:
BearSSL::WiFiClientSecure - WiFiClient that supports TLS
BearSSL::WiFiServerSecure - WiFiServer supporting TLS and client certs

It also introduces objects for PEM/DER encoded keys and certificates:
BearSSLX509List - x.509 Certificate (list) for general use
BearSSLPrivateKey - RSA or EC private key
BearSSLPublicKey - RSA or EC public key (i.e. from a public website)

Finally, it adds a Certificate Authority store object which lets
BearSSL access a set of trusted CA certificates on SPIFFS to allow it
to verify the identity of any remote site on the Internet, without
requiring RAM except for the single matching certificate.
CertStoreSPIFFSBearSSL - Certificate store utility

Client certificates are supported for the BearSSL::WiFiClientSecure, and
what's more the BearSSL::WiFiServerSecure can also *require* remote clients
to have a trusted certificate signed by a specific CA (or yourself with
self-signing CAs).

Maximum Fragment Length Negotiation probing and usage are supported, but
be aware that most sites on the Internet don't support it yet.  When
available, you can reduce the memory footprint of the SSL client or server
dramatically (i.e. down to 2-8KB vs. the ~22KB required for a full 16K
receive fragment and 512b send fragment).  You can also manually set a
smaller fragment size and guarantee at your protocol level all data will
fit within it.

Examples are included to show the usage of these new features.

axTLS has been moved to its own namespace, "axtls".  A default "using"
clause allows existing apps to run using axTLS without any changes.

The BearSSL::WiFi{client,server}Secure implements the axTLS
client/server API which lets many end user applications take advantage
of BearSSL with few or no changes.

The BearSSL static library used presently is stored at
https://github.com/earlephilhower/bearssl-esp8266 and can be built
using the standard ESP8266 toolchain.

f2c7256539 Add flash for vtable destination, make it default, and add build menu to control options (#4582)
* Add flash for vtable destination, make it default

Add an option for placing vtables in flash to complement the existing
iram and heap options.  "make flash"

Now that there is a way to change it, move to vtables in flash as default
as only users with interrupts which use vtables require the vtable to
be in RAM.  For those users, if the tables are small enough they can put
them in IRAM and save heap space for their app.  If not, then the vtables
can be placed in HEAP which supports much larger tables.

* Add VTable menu, FLASH as default, remove Makefile

Convert from manual "make" operated app.ld creation to runtime creation
whose options are selected from the build menu.

Use a prelink recipe to create the output app.ld file each run, without
need for any special tools.

Update the boards.txt.py script to generate this new config.

855b03ce4d Fix exception handler, add assert, reduce RAM (#4187)
Move all exception strings to IRAM and out of both PMEM (illegal) and add
output of any assert() failinf conditions.

The exception handler may be called while the SPI interface is in a bad
state.  This means no PROGMEM reads are allowed, and all data and functions
used must be in system RAM or IRAM.

Add a new helper macro, ets_printf_P(), which places a constant string in
IRAM and copies it to the stack before calling the real ets_printf().
This makes the code simpler to read as no unwieldy combinations of
ets_putc/ets_printf/... are required to output anything.

The old handler also mistakenly used PSTR() strings in some places, so
fix those with this patch as well.

Gives back ~180 bytes of heap to every sketch built as the exception handler
is always included an application.

bb794f9e02 Move C++ vtables into IRAM, out of HEAP (#4179)
GCC places vtables in .rodata, with a mangled name of "_ZTV*."  Because
these are simply address jump tables, there is no need to place them in
RAM.  Instead, have the linker place them in the .text (aka IRAM) section.
This will free up a variable amount of heap space, depending on the number
of classes with virtual functions used in any particular project.

approach as with SHA256, that is to copy padding to the stack first, and
then pass it to Update.
