Merge tag 'v1.8.2' into parse-bytecode

Thread support, ESP8266 memory improvements, btree module, improved docs

This release brings multi-threading support in the form of the _thread
module, which closely matches the semantics of the corresponding CPython
module.  There is support for GIL and non-GIL builds; without the GIL
enabled one must protect concurrent access to mutable Python state at the
Python level using Lock objects.  Threading with the GIL is enabled in
the cc3200 port on the WiPy.  Threading without the GIL is enabled on the
unix port.  The ESP8266 port has support for frozen bytecode (for scripts
in the modules/ subdirectory), as well as optimisations for reduced
memory usage and decreased memory fragmentation.  The ESP8266 RTC also
resumes correctly after a deepsleep.  An initial "btree" module has been
implemented for database support (unix port only), and the documentation
has been further improved, with pre-built PDF versions of the docs now
available.
