py/objarray: Split out header to allow direct access to object.
...
This follows source code/header file organization similar to few other
objects, and intended to be used only is special cases, where efficiency/
simplicity matters.

extmod/moduos_dupterm: Reserve buffer bytearray object for dupterm.

Allocating it for each read/write operation is a memory fragmentation
hazard.

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.

enough room to recover from hitting the stack limit.

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/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.

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.

extmod/machine_pinbase: Implementation of PinBase class.
...
Allows to translate C-level pin API to Python-level pin API. In other
words, allows to implement a pin class and Python which will be usable
for efficient C-coded algorithms, like bitbanging SPI/I2C, time_pulse,
etc.

py/makeqstrdefs.py: Remove restriction that source path can't be absolute.
...
That's arbitrary restriction, in case of embedding, a source file path may
be absolute. For the purpose of filtering out system includes, checking
for ".c" suffix is enough.

extmod/virtpin: Initial implementation of open-ended C-level Pin interface.
...
Using usual method of virtual method tables. Single virtual method,
ioctl, is defined currently for all operations. This universal and
extensible vtable-based method is also defined as a default MPHAL
GPIO implementation, but a specific port may override it with its
own implementation (e.g. close-ended, but very efficient, e.g. avoiding
virtual method dispatch).
