Add esp32.wake_on_ulp() to give access to esp_sleep_enable_ulp_wakeup(),
which is needed to allow the ULP co-processor to wake the main CPU from
deep sleep.

Allow esp32.ULP.load_binary() to use the maximum amount of memory available
again, which is 2040 bytes unless MICROPY_HW_RTC_USER_MEM_MAX is
customized.

Using it for the rx-timeout. The value is given as ms, which is then
converted to character times. A value of less than a character time will
cause the rx call to return immediately after 1 character, which may be
inefficient at high transmission rates.

Individual boards must enable it via MICROPY_HW_USB_CDC_1200BPS_TOUCH.

|
|
|
Currently this file only includes a CDC jump-to-bootloader helper function.
|
|
If the serial port is closed with baudrate at 1200 then the board will
enter its bootloader.

This is no longer needed with new uasyncio v3, and disabling it saves 900
bytes.

Prior to this commit, complex("j") would return 0j, and complex("nanj")
would return nan+0j. This commit makes sure "j" is tested for after
parsing the number (nan, inf or a decimal), and also supports the case of
"j" on its own.

This changes the btree implementation to use the buffer protocol for
reading key/values in all methods. `str` and `bytes` objects are not the
only bytes-like objects that could be used.
Documentation and tests are also updated.

This separates extmod source files from `py.mk`. Previously, `py.mk`
assumed that every consumer of the py/ directory also wanted to include
extmod/. However, this is not the case. For example, building mpy-cross
uses py/ but doesn't need extmod/.
This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and
explicitly includes `extmod.mk` in ports that use it.

The following changes are made:
- Guard entire file with MICROPY_PY_LWIP, so it can be included in the
build while still being disabled (for consistency with other extmod
modules).
- Add modlwip.c to list of all extmod source in py/py.mk and
extmod/extmod.cmake so all ports can easily use it.
- Move generic modlwip GIT_SUBMODULES build configuration code from
ports/rp2/CMakeLists.txt to extmod/extmod.cmake, so it can be reused by
other ports.
- Remove now unnecessary inclusion of modlwip.c in EXTMOD_SRC_C in esp8266
port, and in SRC_QSTR in mimxrt port.

This new logic tracks when an unconditional jump/raise occurs in the
emitted code stream (bytecode or native machine code) and suppresses all
subsequent code, until a label is assigned. This eliminates a lot of
cases of dead code, with relatively simple logic.
This commit combined with the previous one (that removed the existing
dead-code finding logic) has the following code size change:
bare-arm: -16 -0.028%
minimal x86: -60 -0.036%

The search in these cases should include all finally handlers that are
after the current ip. If a handler starts at exactly ip then it is
considered "after" the ip. This can happen when END_FINALLY is followed
immediately by a finally handler (from a different finally).
Consider the function:
def f():
try:
return 0
finally:
print(1)
The current bytecode emitter generates the following code:
00 SETUP_FINALLY 5
02 LOAD_CONST_SMALL_INT 0
03 RETURN_VALUE
04 LOAD_CONST_NONE ****
05 LOAD_GLOBAL print
07 LOAD_CONST_SMALL_INT 1
08 CALL_FUNCTION n=1 nkw=0
10 POP_TOP
11 END_FINALLY
12 LOAD_CONST_NONE
13 RETURN_VALUE
The LOAD_CONST_NONE marked with **** is dead code because it follows a
RETURN_VALUE, and nothing jumps to this LOAD_CONST_NONE. If the emitter
could remove this this dead code it would produce:
00 SETUP_FINALLY 4
02 LOAD_CONST_SMALL_INT 0
03 RETURN_VALUE
04 LOAD_GLOBAL print
06 LOAD_CONST_SMALL_INT 1
07 CALL_FUNCTION n=1 nkw=0
09 POP_TOP
10 END_FINALLY
11 LOAD_CONST_NONE
12 RETURN_VALUE
In this case the finally block (which starts at offset 4) immediately
follows the RETURN_VALUE. When RETURN_VALUE executes ip will point to
offset 4 in the bytecode (because the dispatch of the opcode does *ip++)
and so the finally handler will only be found if a >= comparison is used.
It's a similar story for break/continue:
while True:
try:
break
finally:
print(1)
Although technically in this case the > comparison still works because the
extra byte from the UNWIND_JUMP (encoding the number of exception handlers
to unwind) doesn't have a *ip++ (just a *ip) so ip remains pointing within
the UNWIND_JUMP opcode, and not at the start of the following finally
handler. Nevertheless, the change is made to use >= for consistency with
the RETURN_VALUE change.

Rename WLAN keyword args to scan(), connect() and config() to be more
consistent across ports and WLAN drivers. This change is backwards
compatible and will support obsolete keyword args, except for positional
"essid" which is now deprecated in favor of "ssid".
The changed argument names are
- "essid" changed to "ssid"
- "auth" or "authmode" changed to "security"
- "password" changed to "key"

The CI scripts were using a PPA to get a backported version of uncrustify
on Ubuntu 20.04. However, this causes CI to intermittently fail due to
connection issues to launchpad.net or the key server.
Ubuntu 22.04 has a newer version of uncrustify removing the need for the
PPA. Ubuntu 22.04 is now in beta on GitHub actions, so it can be used.

When MICROPY_PY_MACHINE_I2C_TRANSFER_WRITE1 is enabled the port's hardware
I2C transfer functions should support the MP_MACHINE_I2C_FLAG_WRITE1
option, but software I2C will not. So add a flag to the I2C protocol
struct so each individual protocol can indicate whether it supports this
option or not.
