py/nlrsetjmp: Update to take into account new location of nlr_top.
...
It's now accessed via the MP_STATE_THREAD macro.

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.

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

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.

Simply raises the SystemExit exception.

py/objtype: instance: Inherit protocol vtable from a base class.
...
This allows to define an abstract base class which would translate
C-level protocol to Python method calls, and any subclass inheriting
from it will support this feature. This in particular actually enables
recently introduced machine.PinBase class.
