Damien George df08c38c28 unix/modselect: Remove unix-specific implementation of select module.
The unix port has a custom select module which only works with objects that
have a file descriptor, eg files and sockets.  On the other hand, bare
metal ports use the common extmod/modselect.c implementation of the select
module that supports polling of arbitrary objects, as long as those objects
provide a MP_STREAM_POLL in their ioctl implementation (which can be done
in C or Python).

This commit removes the unix-specific code and makes unix use the common
one provided by extmod/modselect.c instead.  All objects with file
descriptors implement MP_STREAM_POLL so they continue to work.

Damien Tournoud 2dcd745434 py/gc: Speed up incremental GC cycles by tracking the last used block.
In applications that use little memory and run GC regularly, the cost of
the sweep phase quickly becomes prohibitives as the amount of RAM
increases.

On an ESP32-S3 with 2 MB of external SPIRAM, for example, a trivial GC
cycle takes a minimum of 40ms, virtually all of it in the sweep phase.

Similarly, on the UNIX port with 1 GB of heap, a trivial GC takes 47 ms,
again virtually all of it in the sweep phase.

This commit speeds up the sweep phase in the case most of the heap is empty
by keeping track of the ID of the highest block we allocated in an area
since the last GC.

The performance benchmark run on PYBV10 shows between +0 and +2%
improvement across the existing performance tests.  These tests don't
really stress the GC, so they were also run with gc.threshold(30000) and
gc.threshold(10000).  For the 30000 case, performance improved by up to
+10% with this commit.  For the 10000 case, performance improved by at
least +10% on 6 tests, and up to +25%.

Daniël van de Giessen 52dc48b2a0 esp32/machine_wdt: Allow feeding WDT from threads.
This changes the ESP32 WDT implementation to use a custom handle so that it
becomes possible to reset the WDT from a thread.

By default esp_task_wdt_add subscribes the task_id of the current task.
That means that if we're running in a different task we are unable to reset
the WDT, which prevents feeding the WDT from a thread directly, or even
from a timer (which may randomly run in a different task when there's
multiple threads).

As an added bonus, the name we set makes the error clearly specify that it
was the user-specified WDT that reset the chip.

Damien George 8ef5622b9b py/runtime: Always initialise sched_state in mp_init.
When MICROPY_SCHEDULER_STATIC_NODES is enabled, the logic is unchanged.

When MICROPY_SCHEDULER_STATIC_NODES is disable, sched_state is now always
initialised to MP_SCHED_IDLE when calling mp_init().  For example, the use
of mp_sched_vm_abort(), if it aborts a running scheduled function, can lead
to the scheduler starting off in a locked state when the runtime is
restarted, and then it stays locked.  This commit fixes that case by
resetting sched_state.

Damien George c4feb806e0 lib/uzlib: Add memory-efficient, streaming LZ77 compression support.
The compression algorithm implemented in this commit uses much less memory
compared to the standard way of implementing it using a hash table and
large look-back window.  In particular the algorithm here doesn't allocate
hash table to store indices into the history of the previously seen text.
Instead it simply does a brute-force-search of the history text to find a
match for the compressor.  This is slower (linear search vs hash table
lookup) but with a small enough history (eg 512 bytes) it's not that slow.
And a small history does not impact the compression too much.

To give some more concrete numbers comparing memory use between the
approaches:

- Standard approach: inplace compression, all text to compress must be in
  RAM (or at least memory addressable), and then an additional 16k bytes
  RAM of hash table pointers, pointing into the text

- The approach in this commit: streaming compression, only a limited amount
  of previous text must be in RAM (user selectable, defaults to 512 bytes).

To compress, say, 1k of data, the standard approach requires all that data
to be in RAM, plus an additional 16k of RAM for the hash table pointers.
With this commit, you only need the 1k of data in RAM.  Or if it's
streaming from a file (or elsewhere), you could get away with only 256
bytes of RAM for the sliding history and still get very decent compression.

In summary: because compression takes such a large amount of RAM (in the
standard algorithm) and it's not really suitable for microcontrollers, the
approach taken in this commit is to minimise RAM usage as much as possible,
and still have acceptable performance (speed and compression ratio).

Damien George cb31c0ae9c esp32: Add support for board-named pins and the Pin.board dict.
This adds named-pins support to the esp32 port, following other ports.
Since the name of esp32 CPU pins is just GPIOx, where x is an integer, the
Pin.cpu dict is not supported and CPU pins are just retrieved via their
existing integer "name" (the cost of adding Pin.cpu is about 800 bytes,
mostly due to the additional qstrs).

What this commit supports is the Pin.board dict and constructing a pin by
names given by a board.  These names are defined in a pins.csv file at the
board level.  If no such file exists then Pin.board exists but is empty.

As part of this commit, pin and pin IRQ objects are optimised to reduce
their size in flash (by removing their gpio_num_t entry).  The net change
in firmware size for this commit is about -132 bytes.

robert-hh 29e9573de7 esp32: Use always machine_pin_get_id for getting a Pin id.
This applies to all machine modules which have pins as arguments.  Since
machine_pin_get_id() calls pin_find(), these pin arguments may be at the
moment either integer objects or Pin objects.  That allows for instance to
write

    uart = UART(1, tx=Pin(4), rx=Pin(5))

instead of

    uart = UART(1, tx=4, rx=5)

which is consistent with other ports.  Since this handling is done at a
single place in the code, extending that scheme to accept strings for named
pins is easy.
