py: Move locals/globals dicts to the thread-specific state.
...
Each threads needs to have its own private references to its current
locals/globals dicts, otherwise functions running within different
contexts (eg imported from different files) can behave very strangely.

py/modthread: Use system-provided mutexs for _thread locks.
...
It's more efficient using the system mutexs instead of synthetic ones with
a busy-wait loop. The system can do proper scheduling and blocking of the
threads waiting on the mutex.

py: Use mp_raise_msg helper function where appropriate.
...
Saves the following number of bytes of code space: 176 for bare-arm, 352
for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266.

py: Add mp_raise_OSError(errno) helper function.
...
This is an often used code pattern, and its use reduces code size of the
core by about 100 bytes.

py/modthread: Allow to properly set the stack limit of a thread.
...
We rely on the port setting and adjusting the stack size so there is
enough room to recover from hitting the stack limit.

py: Implement a simple global interpreter lock.
...
This makes the VM/runtime thread safe, at the cost of not being able to
run code in parallel.

py/modthread: Call mp_thread_start/mp_thread_finish around threads.
...
So the underlying thread implementation can do any necessary bookkeeping.
