It is likely due to the multiple heap setup on ESP32. An allocation
fails into one heap because the size is too large but caused an
assertion instead of failing over to the next heap.
Fixes#9026
The original implementation couldn't allocate to a region that was
just freed even though the freed region was the same size as the
new request. This was due to allocation sizes being rounded up
during search but not when marking the region in use.

- add tuh_event_hook_cb() in SRAM, required when updated to latest tinyusb
- bump up pico-pio-usb to latest
- bump up tinyusb to latest for new tuh_hid_receive_abort(), and all endpoint abort when

the mbedtls version is a bit different so there are some new #ifdefs
needed.
Tested with the ssl test from https://github.com/adafruit/circuitpython/issues/8910
on Adafruit MatrixPortal S3 (no pico w testing done)
The new ones handle resource tracking for us. They also do a
better job running when the flash cache is disabled, which is the
source of bugs when interacting with flash over USB.
Fixes#6998 and fixes#8379
This simplifies allocating outside of the VM because the VM doesn't
take up all remaining memory by default.
On ESP we delegate to the IDF for allocations. For all other ports,
we use TLSF to manage an outer "port" heap. The IDF uses TLSF
internally and we use their fork for the other ports.
This also removes the dynamic C stack sizing. It wasn't often used
and is not possible with a fixed outer heap.
Fixes#8512. Fixes#7334.
The primary purpose of this commit is to make decompress default to
wbits=15 when the format is gzip (or auto format with gzip detected). The
idea is that someone decompressing a gzip stream should be able to use the
default `deflate.DeflateIO(f)` and it will "just work" for any input
stream, even though it uses a lot of memory.
This is done by making uzlib report gzip files as having wbits set to 15
in their header (where it previously only set the wbits out parameter for
zlib files), and then fixing up the logic in `deflateio_init_read`.
Updates the documentation to match.
