Previously the interaction between the different layers of the Bluetooth
stack was different on each port and each stack. This commit defines
common interfaces between them and implements them for cyw43, btstack,
nimble, stm32, unix.
mp_irq_init() is useful when the IRQ object is allocated by the caller.
The mp_irq_methods_t.init method is not used anywhere so has been removed.

This is consistent with the other 'micro' modules and allows implementing
additional features in Python via e.g. micropython-lib's sys.
Note this is a breaking change (not backwards compatible) for ports which
do not enable weak links, as "import sys" must now be replaced with
"import usys".
Verifies mtime timestamps on files match the value returned by time.time().
Also update vfs_fat_ramdisk.py so it doesn't check FAT timestamp of the
root, because that may change across runs/ports.

By setting MICROPY_EPOCH_IS_1970 a port can opt to use 1970/1/1 as the
Epoch for timestamps returned by stat(). And this setting is enabled on
the unix and windows ports because that's what they use.

On 32-bit builds these stat fields will overflow a small-int, so use
mp_obj_new_int_from_uint to construct the int object.

On ports like unix where the Epoch is 1970/1/1 and atime/mtime/ctime are in
seconds since the Epoch, this value will overflow a small-int on 32-bit
systems. So far this is only an issue on 32-bit unix builds that use the
VFS layer (eg dev and coverage unix variants) but the fix (using
mp_obj_new_int_from_uint instead of MP_OBJ_NEW_SMALL_INT) is there for all
ports so as to not complicate the code, and because they will need the
range one day.
Also apply a similar fix to other fields in VfsPosix.stat because they may
also be large.

gettimeofday returns seconds since 2000/1/1 so needs to be adjusted to
seconds since 1970/1/1 to give the correct return value of mp_hal_time_ns.

This commit fixes the cases when a TCP socket is in STATE_NEW,
STATE_LISTENING or STATE_CONNECTING and recv() is called on it. It now
raises ENOTCONN instead of a random error code due to it previously
indexing beyond the start of error_lookup_table[].

Updating to Black v20.8b1 there are two changes that affect the code in
this repository:
- If there is a trailing comma in a list (eg [], () or function call) then
that list is now written out with one line per element. So remove such
trailing commas where the list should stay on one line.
- Spaces at the start of """ doc strings are removed.

So they can be skipped if __rOP__'s are not supported on the target. Also
fix the typo in the complex_special_methods.py filename.

The memory operation functions read_mem() and write_mem() create a
temporary buffer on the local C stack for the address bytes with the size
of 4 bytes. This buffer is filled in a loop from the user supplied address
and address length. If the user supplied 'addrsize' is bigger than 32, the
local buffer is overrun.
Fix this by raising an exception for invalid 'addrsize' values.
