eef7eae6b2 esp8266/modesp: Remove esp.info() function.
The main functionality of this info function is available via the existing
micropython.mem_info() and micropython.qstr_info() functions.  The printing
of the address space layout doesn't add much and removing esp.info() saves
about 600 bytes.

7684c996bc esp32/machine_pin: Add new hold keyword argument and remove PULL_HOLD.
The current pull=Pin.PULL_HOLD argument doesn't make a lot of sense in the
context of what it actually does vs what the ESP32 quickref document says
it does.

This commit removes PULL_HOLD and adds a new hold=True|False keyword
argument to Pin()/Pin.init().  Setting this to True will cause the ESP32 to
lock the configuration of the pin – including direction, output value,
drive strength, pull-up/-down – such that it can't be accidentally changed
and will be retained through a watchdog or internal reset.

Fixes issue #8283, and see also #8284.

The bytecode state variables mp_showbc_code_start and mp_showbc_constants
have been removed and made local variables passed into the various
functions.

As part of this, the DECODE_PTR macro is fixed so it extracts the relevant
pointer from the child_table (a regression introduced in

3356b5ef8d py/objmodule: Support delegating failed attr lookups.
This commit adds generic support for mutable module attributes on built in
modules, by adding support for an optional hook function for module
attribute lookup.  If a module wants to support additional attribute load/
store/delete (beyond what is in the constant, globals dict) then it should
add at the very end of its globals dict MP_MODULE_ATTR_DELEGATION_ENTRY().
This should point to a custom function which will handle any additional
attributes.

The mp_module_generic_attr() function is provided as a helper function for
additional attributes: it requires an array of qstrs (terminated in
MP_QSTRnull) and a corresponding array of objects (with a 1-1 mapping
between qstrs and objects).  If the qstr is found in the array then the
corresponding object is loaded/stored/deleted.

2b409ef8a4 unix/moduos: Convert module to use extmod version.
All variants now use extmod/moduos.c as their uos module implementation.
In particular this means they all have MICROPY_VFS enabled and use VfsPosix
for their filesystem.

As part of this, the available functions in uos become more consistent with
other ports:
- coverage variant gets uos.urandom
- minimal and standard variant get: unlink, chdir, getcwd, listdir

e0b97013d0 mimxrt/hal/pwm_backport: Make PWM symmetric, and round division calcs.
Ensure the symmetry of PWM: the duty rate of X and Q channels was not 50%,
when it should have been.  That is evident at high frequencies, like 15Mhz
or 37.5 MHz.  At low frequencies the deviation mattered less.  The A/B
channels were fine.

Also round up or down non-integer division factors. Before, always the
floor value was used.

b0d460cd7d mimxrt/eth: Fix an Ethernet transmit error.
Sometimes frames could not be sent immediately because the controller was
still busy with previous frames.  Then, an error was returned to lwip.
This fix adds a limited number of retries for this busy state, waiting
100µs before the next attempt.  Typically the transmit succeeds now at the
second attempt.

Second change: Reset the controller for a clean state after soft reset.
