* (test) WString: c_str() returns null pointer
target = std::move(source) does not reset buffer pointer back to the sso
* wstring: correctly do move invalidation & copy
based on the #7553 without isSSO -> isHeap rename and inline optimizations
additionally, remove useless pre-c++11 preprocessor checks

* Update certs-from-mozilla.py
Check if ar exists, if not tell the user what to get to prevent issue #7300 also dynamically get certs instead of hardcoded row item https://github.com/esp8266/Arduino/pull/7573#issuecomment-686192353
changed comment for missing ar exception
updated path and check for openssl
Simple example update to pass the method as a parameter to getDigestAuth(), so it is more easily used for POST.
Add setting the ransom seed to RANDOM_REG32 in setup() for better getCNonce() values.
The last 4 bytes of a GZIP file is the decompressed file length, and
are used in eboot to do sanity checks and know when decompression is
done.
Updater was incorrectly telling eboot to look at
"end-of-bin + sizeof(signing)", and when eboot did so it got an
incorrect value causing either the update to be skipped or for only a
portion of update to be completed.
Fix by adjusting the size back to the end of binary.
Fixes#7570
Although GCC seems to be able to grok it, it looks weird
in my editor. this is the only place in the code base where
this combination is used, so I hope its okay to remove it.
The logic can be simplified by using integer logic without a functional
change. Reduces code size by 40% (78 bytes -> 46 bytes) and silences
a Warith-conversion warning.
Converting floats to doubles is very expensive on esp8266, so prefer
calculations or comparisons as float. This saves 10% (20 bytes) of the
String::parseFloat() code size and probably quite a bit of runtime
overhead.
Check that building the eboot.c block generates the same binary as
the verison checked into the repo. Catches the case where a library
or eboot.c file is changed, but an updated eboot.elf isn't included
in a PR.
Can't do simple binary diff of the ELFs because paths and compile
times will change, so dump the two sections we care about.
There is a window where the eboot sector is erased and
unwritten/partially written. If there's a power cycle at this time, the
chip will brick due to eboot being corrupted.
Avoid this by checking if the new eboot 4K sector is identical to the
one already in flash, and if so don't rewrite it.
