* Added convert method to transfer data from partition to nvs
* Could have sworn I changed the return when I made the label
* Empty state should be 0xFF. Fixed some logging levels
* Set result on success
* Expand gitignore to cover files created by Visual Micro's Arduino IDE for Visual Studio
(cherry picked from commit d6209c79ea16a26564fe27e74e5f277160129847)
* Also ignore VS project files
(cherry picked from commit e0ec212bd41e75a3570a6098a66ee66787db58db)
* Other Arduino cores uses a macro to redefine libc abs() to take any
type, meaning abs(-3.3) == 3.3 not the normal libc result of 3.
* 1e4bf14a3 (#1783) replaced similar min, max macros with c++ stdlib. However
this change includes <algorithm> after the line which defines the abs() macro.
<algorithm> includes <cstdlib> which undefines abs() and re-defines it.
* This means abs() becomes the plain libc version again which only takes
integers, so abs(-3.3) == 3. As reported here:
https://github.com/espressif/esp-idf/issues/3405
This fix tries to keep in the spirit of #1783 by using libstdc++. The other
option would be to include <cstdlib> before defining the abs() macro, so it
doesn't get undef-ed again later on.

With SSO implementation in String, StreamString::write generates wrong
strings under some circumstances. Reason is that String::len() returns
strlen(sso_buf) if SSO=true but with newly written data
(in StreamString::write) the null-termination missing at the time len()
is called.
Furthermore, len() is called twice which is inefficient if SSO=true.
* Fix semaphores in IDF & std::string assert
Fixes the problem of giving a mutex from a callback with the latest IDF. Also addresses an occasional assert that happens when the btc_task callback gives the semaphore and causes an assert due to both cores potentially writing m_owner concurrently.
* Restored m_owner position in wait() as requested
* Reapply assert fix and move setting m_owner in ::give()
Revert previous revert commit and move setting of m_owner in ::give to before giving the semaphore to prevent race condition possibility.
Implemented the ability to change the ESP32s BLE device address as
according the the BLE specification. This address is used when
advertising the ESP32 over BLE.
I redid the ESP8266 WString library to enable small string optimization
(SSO) a while back, and think it would be helpful even on the ESP32 with
its higher memory complement.
SSO avoids lots of tiny mallocs() on the heap which cause fragmentation
by using the memory in the class object itself to store the actual
string and only mallocing() for buffers that are larger than what can
fit in thie class object. Modern C++ std::string implementations have
this optimization as well, but since we're using Arduino strings we had
to roll our own.
* Converted EEPROM library to use nvs instead of partition. Removed eeprom partition from all partition table CSV files.
* Changed variable names, added some comments, formatting as per me-no-dev's requests
* Checks for memory on malloc
* Moved include nvs.h from header to code
* Reworked the extra example to make it more clear how to actually use the library and persist data
