This avoids the null termination requirement of both String::substring and String::lastIndexOf by using APIs that don't require it. So we can stop writing to the buffer inside of const functions.
I also changed wbuffer to make it non const.
The existing ESP8266SdFat points to a working branch of the tree.
That branch is now merged to master, so move library to it.
There are no code changes,
* Fix VM Address mask
Adjust VM Address mask to allow up to 8M Byte parts.
Allow for free heap size values over 64K
ESP.getHeapStats(, uint32_t,)
uint32_t getMaxFreeBlockSize();
* Fix example
* Update MockEsp.cpp for uint32_t on EspClass::getMaxFreeBlockSize()
* Added comment about heap size limitation and static_assert to verify.
Updated boards.txt to show correct External memory size and Heap size.
PWMRANGE was defined up until v2.7.4:
```
$ cd ~/Library/Arduino15/packages/esp8266/hardware/esp8266
$ grep -R "PWMRANGE" 2.7.4
2.7.4/keywords.txt:PWMRANGE LITERAL1
2.7.4/tests/host/common/Arduino.h:#define PWMRANGE 1023
2.7.4/cores/esp8266/core_esp8266_wiring_pwm.cpp:static int32_t analogScale = PWMRANGE;
2.7.4/cores/esp8266/Arduino.h:#define PWMRANGE 1023
```
The define was removed in favour of the Arduino standard value of 255
but the keyword coloring was left behind:
```
$ cd ~/Library/Arduino15/packages/esp8266/hardware/esp8266
$ grep -R "PWMRANGE" 3.0.2
3.0.2/keywords.txt:PWMRANGE LITERAL1
```
In the Arduino IDE, the coloring makes it look like PWMRANGE still
exists, when it doesn't, which is confusing.

Upstream umm_malloc at git hash id 4dac43c3be7a7470dd669323021ba238081da18e
processed all project files with the style program uncrustify.
This PR updates our ported version of umm_malloc processed with "uncrustify".
This should make subsequent merges of upstream into this port easier.
This also makes the style more consistant through umm_malloc.
* WiFiServer - 'rename' available() to accept()
* use server.accept() instead of available()
* WiFiServer.accept() and ArduinoWiFiServer class doc update
* StreamConstPtr: prevent from passing a temporary String instance
* unconditionally allow progmem chars
* missing virtual destructor in Stream
(warning: deleting object of abstract class type 'Stream' which has non-virtual destructor will cause undefined behavior [-Wdelete-non-virtual-dtor])
Extracted fix from upstream for umm_blocks() - On allocations that were too
large, umm_blocks() could return an incorrectly truncated value when the result
is cast to uint16_t.
* Enable I2C_BUFFER_LENGTH definition for Wire lib
Based on
375a89ed58
We should have been very careful when #defining things to not use a name
that could conflict with the user's own code, so this marks that old
define as deprecated.
If you opt-into the new behavior, you do not get the old BUFFER_LENGTH
constant.
As a bonus, changing these uint8_ts to size_t both reduces the code
size & improves performance.
* Increase buffer indexing variable size
I looked over the users of these variables and they should be fine with
no additional changes. The existing methods already have an option to
use size_t rather than uint8_t.
There's a few methods which return int instead of size_t, which isn't
great from a portability perspective but will be fine since this only is
designed to run on the ESP8266.
* A clock phase correction in write_start(void)
Some devices require the data wire SDA to be held down at the moment while the clock wire is pulled down too to execute the start condition (e.g. devices using "TinyWires.h" library). This change follows a behaviour of Arduino Wire.h library, where the SCL signal is pulled down in half of period of start condition.
* Formatting of modification restyled
* Removing mathematical operations from delay
* Comments added
* Remove warnings, errors during host tests in CI
Debug strings often included format parameters which did not exactly match
the passed in format parameters, resulting in warnings in the host test build
process like
````
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiAP.cpp:107:20: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 3 has type ‘size_t’ {aka ‘long unsigned int’} [-Wformat=]
107 | DEBUG_WIFI("[AP] SSID length %u, too long or missing!\n", ssid_len);
| ~~~~~~~~

| size_t {aka long unsigned int}
````
Fix by applying casting or PRxxx macros as appropriate.
Also, fix one debug message which was trying to use a `String` as a `char *`:
````

* Clean up SpeedTest.ino host build
Added Flash mode and reset method selection options for Olimex board MOD-WIFI-ESP8266(-DEV)
The addition of the FlashMode and ResetMethod selection options via boards.txt.py generation file.
* EspSoftwareSerial 6.14.0: Add API for selecting Rx GPIO PULLUP at runtime.
* EspSoftwareSerial: bug fix 6.14.1: Set default RX pullup once in ctor, prevents flipping of that state on begin().
* ESP8266WebServer - drop current HC_WAIT_READ connection sooner when another has data
Safari sometimes opens two connections when loading a page and only
sends a request over the second one, resulting in a 5 second wait
(HTTP_MAX_DATA_WAIT) before the request is processed. This commit
drops the current connection after 30ms (HTTP_MAX_DATA_AVAILABLE_WAIT)
when there is a new connection with data available or the buffer of
pending TCP clients is full (currently 5).
Use a formatting function to give more human-readable output formats
for flash bandwidth. When the test starts and ends in less than one
millisecond, report as "Infinite".
Sample output:

esp_yield() now also calls esp_schedule(), original esp_yield() function renamed to esp_suspend().
Don't use delay(0) in the Core internals, libraries and examples. Use yield() when the code is
supposed to be called from CONT, use esp_yield() when the code can be called from either CONT or SYS.
Clean-up esp_yield() and esp_schedule() declarations across the code and use coredecls.h instead.
Implement helper functions for libraries that were previously using esp_yield(), esp_schedule() and
esp_delay() directly to wait for certain SYS context tasks to complete. Correctly use esp_delay()
for timeouts, make sure scheduled functions have a chance to run (e.g. LwIP_Ethernet uses recurrent)

- =default for default ctor, destructor, move ctor and the assignment move
- use `std::unique_ptr<WiFiClient>` instead of raw pointer to the client
- implement `virtual std::unique_ptr<WiFiClient> WiFiClient::clone()` to safely copy the WiFiClientSecure instance, without accidentally slicing it (i.e. using the pointer with incorrect type, calling base WiFiClient virtual methods)
- replace headers pointer array with `std::unique_ptr<T[]>` to simplify the move operations
- substitute userAgent with the default one when it is empty
(may be a subject to change though, b/c now there is a global static `String`)
Allow HTTPClient to be placed inside of movable classes (e.g. std::optional, requested in the linked issue) or to be returned from functions. Class logic stays as-is, only the underlying member types are changed.
Notice that WiFiClient connection object is now copied, and the internal ClientContext will be preserved even after the original WiFiClient object was destroyed.

These changes are needed to address bugs that can emerge with the improved optimization from the GCC 10.3 compiler.
Updated performance inline functions `mmu_get_uint8()`, ... and `mmu_set_uint8()`, ... to comply with strict-aliasing rules.
Without this change, stale data may be referenced. This issue was revealed in discussions on https://github.com/esp8266/Arduino/issues/8261#issue-963529268
Changes to avoid over-optimization of 32-bit wide transfers from IRAM, turning into 8-bit or 16-bit transfers by the new GCC 10.3 compiler. This has been a reoccurring/tricky problem for me with the new compiler.
So far referencing the 32-bit value loaded by way of an Extended ASM R/W output register has stopped the compiler from optimizing down to an 8-bit or 16-bit transfer.
Example:
```cpp
uint32_t val;
__builtin_memcpy(&val, v32, sizeof(uint32_t));
asm volatile ("" :"+r"(val)); // inject 32-bit dependency
...
```
Updated example `irammem.ino`
* do a simple test of compliance to strict-aliasing rules
* For `mmu_get_uint8()`, added tests to evaluate if 32-bit wide transfers were converted to an 8-bit transfer.
