10bddc5c28 stm32/boards/STM32F429DISC: Enable UART as secondary REPL.
The board(s) feature a VCOM through the ST-LINK, this feature is something
to keep around.

4737ff8054 extmod/modlwip: Implement TCP listen/accept backlog.
Array to hold waiting connections is in-place if backlog=1, else is a
dynamically allocated array.  Incoming connections are processed FIFO
style to maintain fairness.

485514f57a esp32: Allocate task TCB and stack from system heap not uPy heap.
This is necessary for two reasons: 1) FreeRTOS still needs the TCB data
structure even after vPortCleanUpTCB has been called, so this latter hook
function cannot free the TCB, and there is no where else to safely delete
it (this behaviour has changed recently in the ESP IDF); 2) when using
external SPI RAM the uPy heap is in this external memory but the task stack
must be allocated from internal SRAM.

Fixes issue #3904.

0233049b79 esp32/mpthreadport: Prevent deadlocks when deleting all threads.
vTaskDelete now immediately calls vPortCleanUpTCB, which requires the
thread_mutex mutex, so vTaskDelete must be called after this mutex is
released.

4f25a8b6a4 tools/pydfu.py: Improve DFU reset, and auto-detect USB transfer size.
A DFU device must be in the idle state before it can be programmed, and
this requires either clearing the status or aborting, depending on its
current state.  Code is added to do this.  And the USB transfer size is now
automatically detected so devices with a size less than 2048 bytes work
correctly.

80aca27a40 unix/modos: Rename unlink to remove to be consistent with other ports.
We standardized to provide uos.remove() as a more obvious and user-friendly
name.  That's what written in the docs.  The Unix port implementation
predates this convention, so update it now.

d94aa577a6 tests/import_long_dyn: Test for "import *" of a long dynamic name.
Such names aren't stored as qstr in module dict, and there was a bug in
"import *" handling which assumed any name in a module dict is a qstr.

5c18730f28 py/runtime: Fix qstr assumptions when handling "import *".
There was an assumption that all names in a module dict are qstr's.
However, they can be dynamically generated (by assigning to globals()),
and in case of a long name, it won't be a qstr. Handle this situation
properly, including taking care of not creating superfluous qstr's for
names starting with "_" (which aren't imported by "import *").

e328a5d469 py/scope: Optimise scope_find_or_add_id to not need "added" arg.
Taking the address of a local variable is mildly expensive, in code size
and stack usage.  So optimise scope_find_or_add_id() to not need to take a
pointer to the "added" variable, and instead take the kind to use for newly
added identifiers.

9201f46cc8 py/compile: Fix case of eager implicit conversion of local to nonlocal.
This ensures that implicit variables are only converted to implicit
closed-over variables (nonlocals) at the very end of the function scope.
If variables are closed-over when first used (read from, as was done prior
to this commit) then this can be incorrect because the variable may be
assigned to later on in the function which means they are just a plain
local, not closed over.

Fixes issue #4272.

c2074e7b66 tests/cmdline/cmd_showbc.py: Fix test to explicitly declare nonlocal.
The way it was written previously the variable x was not an implicit
nonlocal, it was just a normal local (but the compiler has a bug which
incorrectly makes it a nonlocal).

746dbf78d3 py/py.mk: When building axtls use -Wno-all to prevent all warnings.
Building axtls gives a lot of warnings with -Wall enabled, and explicitly
disabling all of them cannot be done in a way compatible with gcc and
clang, and likely other compilers.  So just use -Wno-all to prevent all of
the extra warnings (in addition to the necessary -Wno-unused-parameter,
-Wno-uninitialized, -Wno-sign-compare and -Wno-old-style-definition).

Fixes issue #4182.

af5b509c75 examples/unix/ffi_example: Clean up and update the ffi example.
1. Use uctypes.bytearray_at().

Implementation of the "ffi" module predates that of "uctypes", so
initially some convenience functions to access memory were added
to ffi. Later, they landed in uctypes (which follows CPython's
ctype module).

So, replace undocumented experimental functions from ffi to
documented ones from uctypes.

2. Use more suitable type codes for arguments (e.g. "P" (const void*)
instead of "p" (void*).

3. Some better var naming.

4. Clarify some messages printed by the example.

Examples are added to the beginning of the module docs, similarly to docs
for many other modules.

Improvements to grammar, style, and clarity. Some paragraphs are updated
with better suggestions. A warning added of the effect incorrect usage of
the module may have. Describe the fact that offset range used in one
defined structure is limited.

2411f42ccb extmod/moductypes: Make sizeof() accept "layout" parameter.
sizeof() can work in two ways: a) calculate size of already instantiated
structure ("sizeof variable") - in this case we already no layout; b) size
of structure decsription ("sizeof type"). In the latter case, LAYOUT_NATIVE
was assumed, but there should possibility to calculate size for other
layouts too. So, with this patch, there're now 2 forms:

uctypes.sizeof(struct)
uctypes.sizeof(struct_desc, layout)

a07e56cbd8 tests/basics/class_getattr: Remove invalid test for __getattribute__.
Part of this test was trying to test some functionality of __getattribute__
but this method name was misspelt so it wasn't doing anything useful.
Fixing the typo in this name makes the test fail because MicroPython
doesn't support user defined __getattribute__ methods.  So this part of the
test is removed.  The remaining tests are modified slightly to make it
clearer what they are testing.

0c18633ea9 unix/modusocket: Finish socket.settimeout() implementation.
1. Return correct error code for non-blocking vs timed out socket
(POSIX returns EAGAIN for both, we want ETIMEDOUT in case of timed
out socket). To achieve this, blocking/non-blocking flag is added
to the mp_obj_socket_t, to avoid issuing fcntl() syscall each time
EAGAIN occurs. (mp_obj_socket_t used to be 8 bytes, having some room
in a standard 16-byte alloc block.)

2. Handle socket.settimeout(0) properly - in Python, that means
non-blocking mode, but SO_RCVTIMEO/SO_SNDTIMEO of 0 is infinite
timeout.

3. Overall, make sure that socket.settimeout() call switches blocking
state as expected.
