This contains a string useful for identifying the underlying machine. This
string is kept consistent with the second part of the REPL banner via the
new config option MICROPY_BANNER_MACHINE.
This makes os.uname() more or less redundant, as all the information in
os.uname() is now available in the sys module.

This commit adds the git hash and build date to sys.version. This is
allowed according to CPython docs, and is what PyPy does. The docs state:
A string containing the version number of the Python interpreter plus
additional information on the build number and compiler used.
Eg on CPython:
Python 3.10.4 (main, Mar 23 2022, 23:05:40) [GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.version
'3.10.4 (main, Mar 23 2022, 23:05:40) [GCC 11.2.0]'
and PyPy:
Python 2.7.12 (5.6.0+dfsg-4, Nov 20 2016, 10:43:30)
[PyPy 5.6.0 with GCC 6.2.0 20161109] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>> import sys
>>>> sys.version
'2.7.12 (5.6.0+dfsg-4, Nov 20 2016, 10:43:30)\n[PyPy 5.6.0 with GCC ...
With this commit on MicroPython we now have:
MicroPython v1.18-371-g9d08eb024 on 2022-04-28; linux [GCC 11.2.0] v...
Use Ctrl-D to exit, Ctrl-E for paste mode
>>> import sys
>>> sys.version
'3.4.0; MicroPython v1.18-371-g9d08eb024 on 2022-04-28'
Note that the start of the banner is the same as the end of sys.version.
This helps to keep code size under control because the string can be reused
by the compiler.

See issue #5441. This issue is now reproducible on the Arduino Portenta
H747, QSPI flash PN MX25L12833F.

Must always check the FIFO before writing to DR. Without this, this
function hangs on the H747.

Add MPU configuration for common flash sizes up to 256MiB.

Auto-indent still works as the default behaviour, but it is now undone and
disabled if there is a space/tab immediately after an automatically-added
indent. This makes the REPL behaviour closer to CPython, and in particular
allows text to be pasted at the normal REPL.
Addresses issue #7925.

Entering tab at the REPL will now make it insert an indent (4 spaces) in
the following cases:
- after any whitespace on a line
- at the start of a line that is not the first line
This changes the existing behaviour where a tab would insert an indent only
if there were no matches in the auto-complete search, and it was the start
of the line. This means, if there were any symbols in the global
namespace, tab could never be used to indent.
Note that entering tab at the start of the first line will still do
auto-completion, but will now do nothing if there are no symbols in the
global namespace, which is more consistent than before.

These are internal names and can be safely renamed without affecting user
code. push_sorted() and push_head() are merged into a single push()
method, which is already how the C version is implemented. pop_head() is
simply renamed to pop().
The changes are:
- q.push_sorted(task, t) -> q.push(task, t)
- q.push_head(task) -> q.push(task)
- q.pop_head() -> q.pop()
The shorter names and removal of push_head() leads to a code size reduction
of between 40 and 64 bytes on bare-metal targets.

This double-raise test could fail when task[0] raises and stops the gather
before task[1] raises, then task[1] is left to raise later on and spoil the
test.

Per https://docs.python.org/3/reference/expressions.html#membership-test-operations
For user-defined classes which define the contains() method, x in y
returns True if y.contains(x) returns a true value, and False
otherwise.

If isconnected is called before active, it returns -1, which causes

To avoid any I/O glitches in mp_hal_pin_config, make sure a valid alternate
function is set in AFR first before switching the pin mode. When switching
from AF to INPUT or OUTPUT, the AF in AFR will remain valid up until the
pin mode is switched.

This commit adds support to the parser so that tuples which contain only
constant elements (bool, int, str, bytes, etc) are immediately converted to
a tuple object. This makes it more efficient to use tuples containing
constant data because they no longer need to be created at runtime by the
bytecode (or native code).
Furthermore, with this improvement constant tuples that are part of frozen
code are now able to be stored fully in ROM (this will be implemented in
later commits).
Code size is increased by about 400 bytes on Cortex-M4 platforms.
See related issue #722.
