6f70e27011 Base64::encode : const correctness / String by reference passing (#3314)
Avoid passing String by-value, which is slightly less efficient
as it involves a full copy-constructor/tempstring creation.

2f249edb8e Use std::abs for a float-compatible abs() function (#2738)
* 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.

bd57ff4ab4 StreamString SSO fix (#2736)
As found by @mongozmaki in https://github.com/esp8266/Arduino/pull/6035

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.

ab309e40d5 Copy ESP8266 String w/SSO to ESP32 repo (#2715)
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.

9a7946e685 I2C fix READ of zero bytes hardware hang (#2301)
The i2c peripheral will hang if a READ request is issued with a zero data length.  The peripheral
drops into a continuous timeout interrupt response.  The STOP command can not be set out to the I2C
bus. The SLAVE device correctly ACK'd the address byte, with READ bit set, it has control of the SDA
 pin.  The ESP32 send out the next SCL HIGH pulse but, since the SLAVE is in READ Mode, and the First
bit it is sending happened to be a ZERO, the ESP32 cannot send the STOP.  When it releases SDA during
the SCL HIGH, the pin does not change state.  The pin stays low because the SLAVE is outputing a LOW!
The ESP32 drops into a perminent WAIT state waiting for SDA to go HIGH (the STOP).
