This commit adds a workaround for the TWAI listen only mode errata which is
present on the ESP32, ESP32-S2, ESP32-S3, and ESP32-C3. twai_get_status_info()
has also been updated to account for the fact that TEC/REC are frozen in
listen only mode.
Errata Description:
When the TWAI controller is put into listen only mode, it should not influence
the TWAI bus in any way (i.e., should never send a dominant bit). However,
on the targets listed above, the TWAI controller will send dominant bits in an
error frame (i.e., active error frame), even if the controller is set to listen
only mode.
Workaround:
We can force the TWAI controller into the error passive state on startup (by
setting the REC to >= 128). Since the TEC/REC are frozen in listen only mode,
the TWAI controller will remain error passive and only send recessive bits
(i.e., passive error frames), thus will not influence the TWAI bus.

The stream buffer send-receive test preivously contained the following bugs:
- "sender" task would send 101 bytes instead of 100
- The main task would return before "sender" task sends its 101st item. Thus
the sender task would cause memory corruption when accessing "tc" structure
allocated on the main task's stack
This commit fixes and simplifies the stream buffer test.
heap: Fix erroneous value returned by heap_caps_get_allocated_size() when poisoning is enabled (backport v4.4)
See merge request espressif/esp-idf!22189
When light (or comprehensive) poisoning is enabled, the size requested by the user for allocation
is extended by a few bytes to store the canary header and footer. heap_caps_get_allocated_size() should
return the original size asked by the user (without the additional canary bytes).
test_malloc.c extended with a new test assuring that heap_caps_get_allocated_size() returns the proper size
regardless of the degree of poisoning.
When SECURE BOOT V2 is enabled and CONFIG_SECURE_BOOT_SIGNED_BINARIES
is not set, sector-pad the bootloader image, which is required for an
external PKCS#11 interface to generate a signature.
esptool_py: Update submodule to release/v3 (4bc311767b7c6df41def6f95a50f87b1c9406cbd)
When a USB does not support a particular string dsecriptor (e.g.,
manufacturer, product, and serial number), the string descriptors corresponding
index will be set to 0 in the device descriptor (e.g., iManufacturer, iProduct,
iString).
Previously, the Hub driver would always attempt to fetch the all three string
descriptors, thus leading an error in CHECK_SHORT_SER_STR_DESC if the device
did not support the descriptor.
This commit fixes the Hub drvier by skipping the enumeration stages of a
particular descriptor if its index is 0 (i.e., not supported by the device).
USB devices may support string descriptors in multiple languages. The supported
languages are stored in a LANGID table, which itself is a string descriptor at
index 0.
When fetching the LANGID table itself, the USB 2.0 specification does not
specify what LANGID to use, thus the Hub driver would use the default LANGID
"ENUM_LANGID". However, this would cause some devices to stall.
This commit fixes the issue by always requesting the LANGID table itself using
a LANGID of 0.
