py/mpconfig.h: Mention MICROPY_PY_BTREE config option.
...
However, as it requires linking with external libraries, it actually
should be ste on Makefile level.

py/builtinimport: Disable "imported as namespace package" warning.
...
Namespace packages are natural part of Python3, CPython3 doesn't have such
warning, it made sense only from point of view of Python2 legacy.

py/gc: Calculate (and report) maximum contiguous free block size.
...
Just as maximum allocated block size, it's reported in allocation units
(not bytes).

py/gc: Be sure to count last allocated block at heap end in stats.
...
Previously, if there was chain of allocated blocks ending with the last
block of heap, it wasn't included in number of 1/2-block or max block
size stats.

py/nlrthumb: Convert NLR thumb funcs from asm to C with inline-asm.
...
Now only the bits that really need to be written in assembler are written
in it, otherwise C is used. This means that the assembler code no longer
needs to know about the global state structure which makes it much easier
to maintain.

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/mpthread.h: Move GIL macros outside MICROPY_PY_THREAD block.

The GIL macros are needed even if threading is not enabled.

py: Don't use gc or qstr mutex when the GIL is enabled.
...
There is no need since the GIL already makes gc and qstr operations
atomic.

This makes the VM/runtime thread safe, at the cost of not being able to

py/gc: Fix GC+thread bug where ptr gets lost because it's not computed.
...
GC_EXIT() can cause a pending thread (waiting on the mutex) to be
scheduled right away. This other thread may trigger a garbage
collection. If the pointer to the newly-allocated block (allocated by
the original thread) is not computed before the switch (so it's just left
as a block number) then the block will be wrongly reclaimed.
This patch makes sure the pointer is computed before allowing any thread
switch to occur.

py/gc: Make memory manager and garbage collector thread safe.
...
By using a single, global mutex, all memory-related functions (alloc,
free, realloc, collect, etc) are made thread safe. This means that only
one thread can be in such a function at any one time.
