6906255dcd stm32/boards: Remove obsolete and unused board-specific defines.
These board-level macros have been completely replaced by feature-level
config options.

3e9e9b07ba stm32/boards: Add support for NUCLEO-F746ZG evaluation board.
This is a low-cost evaluation kit board from ST based on the STM32
Nucleo-144 form factor.  It uses the STM32F746ZG MCU in the LQFP144
package.  The MCU has 1MB of flash and 320kB of System RAM.
Cortex-M7 runs at up to 216MHz.

12ad64bc55 extmod/vfs_fat: Mount FatFS on creation so VFS methods can be used.
It's possible to use the methods (eg ilistdir) of a VFS FatFS object
without it being mounted in the VFS itself.  This previously worked but
only because FatFS was "mounting" the filesystem automatically when any
function (eg f_opendir) was called.  But it didn't work for ports that used
synchronisation objects (_FS_REENTRANT) because they are only initialised
via a call to f_mount.  So, call f_mount explicitly when creating a new
FatFS object so that everything is set up correctly.  Then also provide a
finaliser to do the f_umount call, but only if synchronisation objects are
enabled (since otherwise the f_umount call does nothing).

8d956c26d1 py/objstr: When constructing str from bytes, check for existing qstr.
This patch uses existing qstr data where possible when constructing a str
from a bytes object.

1f1d5194d7 py/objstr: Make mp_obj_new_str_of_type check for existing interned qstr.
The function mp_obj_new_str_of_type is a general str object constructor
used in many places in the code to create either a str or bytes object.
When creating a str it should first check if the string data already exists
as an interned qstr, and if so then return the qstr object.  This patch
makes the function have such behaviour, which helps to reduce heap usage by
reusing existing interned data where possible.

The old behaviour of mp_obj_new_str_of_type (which didn't check for
existing interned data) is made available through the function
mp_obj_new_str_copy, but should only be used in very special cases.

One consequence of this patch is that the following expression is now True:

    'abc' is ' abc '.split()[0]

4601759bf5 py/objstr: Remove "make_qstr_if_not_already" arg from mp_obj_new_str.
This patch simplifies the str creation API to favour the common case of
creating a str object that is not forced to be interned.  To force
interning of a new str the new mp_obj_new_str_via_qstr function is added,
and should only be used if warranted.

Apart from simplifying the mp_obj_new_str function (and making it have the
same signature as mp_obj_new_bytes), this patch also reduces code size by a
bit (-16 bytes for bare-arm and roughly -40 bytes on the bare-metal archs).

1871a924c9 py/mkenv.mk: Use $(PYTHON) consistently when calling Python tools.
Rationale:

* Calling Python build tool scripts from makefiles should be done
  consistently using `python </path/to/script>`, instead of relying on the
  correct she-bang line in the script [1] and the executable bit on the
  script being set. This is more platform-independent.
* The name/path of the Python executable should always be used via the
  makefile variable `PYTHON` set in `py/mkenv.mk`. This way it can be
  easily overwritten by the user with `make PYTHON=/path/to/my/python`.
* The Python executable name should be part of the value of the makefile
  variable, which stands for the build tool command (e.g. `MAKE_FROZEN` and
  `MPY_TOOL`), not part of the command line where it is used. If a Python
  tool is substituted by another (non-python) program, no change to the
  Makefiles is necessary, except in `py/mkenv.mk`.
* This also solves #3369 and #1616.

[1] There are systems, where even the assumption that `/usr/bin/env` always
exists, doesn't hold true, for example on Android (where otherwise the unix
port compiles perfectly well).

7413b3ce3e extmod/moduhashlib: Enable SHA1 hashing when using "mbedtls" library.
The SHA1 hashing functionality is provided via the "axtls" library's
implementation, and hence is unavailable when the "axtls" library is not being
used.  This change provides the same SHA1 hashing functionality when using the
"mbedtls" library by using its implementation instead.

0719c936fb extmod/modussl_axtls: socket_read: Handle EAGAIN.
If SSL_EAGAIN is returned (which is a feature of MicroPython's axTLS fork),
return EAGAIN.

Original axTLS returns SSL_OK both when there's no data to return to user
yet and when the underlying stream returns EAGAIN. That's not distinctive
enough, for example, original module code works well for blocking stream,
but will infinite-loop for non-blocking socket with EAGAIN. But if we fix
non-blocking case, blocking calls to .read() will return few None's initially
(while axTLS progresses thru handshake).

Using SSL_EAGAIN allows to fix non-blocking case without regressing the
blocking one.

Note that this only handles case of non-blocking reads of application data.
Initial handshake and writes still don't support non-blocking mode and must
be done in the blocking way.

487dbdb267 py/compile: Use alloca instead of qstr_build when compiling import name.
The technique of using alloca is how dotted import names are composed in
mp_import_from and mp_builtin___import__, so use the same technique in the
compiler.  This puts less pressure on the heap (only the stack is used if
the qstr already exists, and if it doesn't exist then the standard qstr
block memory is used for the new qstr rather than a separate chunk of the
heap) and reduces overall code size.

74ec52d857 extmod/modussl: Add finaliser support for ussl objects.
Per the comment found here
https://github.com/micropython/micropython-esp32/issues/209#issuecomment-339855157,
this patch adds finaliser code to prevent memory leaks from ussl objects,
which is especially useful when memory for a ussl context is allocated
outside the uPy heap.  This patch is in-line with the finaliser code found
in many modsocket implementations for various ports.

This feature is configured via MICROPY_PY_USSL_FINALISER and is disabled by
default because there may be issues using it when the ussl state *is*
allocated on the uPy heap, rather than externally.

24c8eda744 unix: Enable MICROPY_PY_REVERSE_SPECIAL_METHODS.
With inplace methods now disabled by default, it makes sense to enable
reverse methods, as they allow for more useful features, e.g. allow
for datetime module to implement both 2 * HOUR and HOUR * 2 (where
HOUR is e.g. timedelta object).

0e80f345f8 py/objtype: Introduce MICROPY_PY_ALL_INPLACE_SPECIAL_METHODS.
This allows to configure support for inplace special methods separately,
similar to "normal" and reverse special methods. This is useful, because
inplace methods are "the most optional" ones, for example, if inplace
methods aren't defined, the operation will be executed using normal
methods instead.

As a caveat, __iadd__ and __isub__ are implemented even if
MICROPY_PY_ALL_INPLACE_SPECIAL_METHODS isn't defined. This is similar
to the state of affairs before binary operations refactor, and allows
to run existing tests even if MICROPY_PY_ALL_INPLACE_SPECIAL_METHODS
isn't defined.

9b9dbc5815 py/objtype: Define all special methods if requested.
If MICROPY_PY_ALL_SPECIAL_METHODS is defined, actually define all special
methods (still subject to gating by e.g. MICROPY_PY_REVERSE_SPECIAL_METHODS).

This adds quite a number of qstr's, so should be used sparingly.

c64eb4f8ce extmod/vfs: Replace VLA in proxy func with small, static sized array.
VLAs can be expensive on stack usage due to stack alignment requirements,
and also the fact that extra local variables are needed to track the
dynamic size of the stack.  So using fixed-size arrays when possible can
help to reduce code size and stack usage.

In this particular case, the maximum value of n_args in the VLA is 2 and so
it's more efficient to just allocate this array with a fixed size.  This
reduces code size by around 30 bytes on Thumb2 and Xtensa archs.  It also
reduces total stack usage of the function: on Thumb2 the usage with VLA is
between 40 and 48 bytes, which is reduced to 32; on Xtensa, VLA usage is
between 64 and 80 bytes, reduced to 32; on x86-64 it's at least 88 bytes
reduced to 80.
