The default is the same as before: MICROPY_PY_USELECT=0 and
MICROPY_PY_USELECT_POSIX=1. But now this can be easily overridden at the
make command-line using, eg:
make VARIANT=dev CFLAGS_EXTRA=-DMICROPY_PY_USELECT=1

For STM32L072 and similar, very low end targets.
The other perf_bench tests run out of memory, crash, or fail on

When tested, this reduces default MP binary sizes by approx 2-2.5%, and
very marginally increases performance in benchmarks. Build times seem very
similar to non-LTO when using gcc 12.
See #8733 for further discussion.

Prerequisite for enabling Link Time Optimisation.
The _bl_state address is the same as _estack, but _estack is referred to as
a uint32_t elsewhere in the code. LTO doesn't like it when the same symbol
has two different types.

Add .attr attribute which forwards to self->fun.
A closure is intended to wrap around a function object, so forward any
requested attributes to the wrapped function object.

Replaces preprocessor macro for SDRAM option from #ifdef to #if in order to
allow always setting the define `MICROPY_HW_SDRAM_AVAIL` just with the
appropriate value 0/1. This eliminates one `if` in the Makefile.
The main aim of this change is to reduce the number of heap allocations
when writing data to a stream. This is done in two ways:
1. Eliminate appending of data when .write() is called multiple times
before calling .drain(). With this commit, the data is written out
immediately if the underlying stream is not blocked, so there is no
accumulation of the data in a temporary buffer.
2. Eliminate copying of non-bytes objects passed to .write(). Prior to
this commit, passing a bytearray or memoryview to .write() would always
result in a copy of it being made and turned into a bytes object. That
won't happen now if the underlying stream is not blocked.
Also, this change makes .write () more closely implement the CPython
documented semantics: "The method attempts to write the data to the
underlying socket immediately. If that fails, the data is queued in an
internal write buffer until it can be sent."
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.
Addresses #8778.
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.
Addresses issue #8748.

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.

dead-code finding logic) has the following code size change:
