If BLK2 is empty then it's OK to continue with a warning (otherwise it may spook users into thinking
something this is wrong, but this is the expected workflow.)
If BLK2 is not empty and doesn't match then we need to fail because it won't be possible to
trust the signature.
`xQueueGenericCreateStatic` is placed into flash by the linker script to
reduce IRAM usage. This will also cause the `xRingbufferCreate` not
not callable when cache is disabled.
The SPI bus lock on SPI1 introduces two side effects:
1. The device lock for the main flash requires the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` to be selected, however this
option is disabled by default in earlier IDF versions. Some developers
may find their project cannot be built by their old sdkconfig files.
2. Usually we don't need the lock on the SPI1 bus, due to it's
restrictions. However the overhead still exists in this case, the IRAM
cost for static version of semaphore functions, and the time cost when
getting and releasing the lock.
This commit:
1. Add a CONFIG_SPI_FLASH_BYPASS_MAIN_LOCK option, which will forbid the
space cost, as well as the initialization of the main bus lock.
2. When the option is not selected, the bus lock is used, the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` will be selected explicitly.
3. Revert default value of `CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION`
to `n`.

We used to manually specify the CS id. However after the SPI bus lock is
introduced, the lock is responsible to assign the CS lines and provide
the CS id. The esp_flash driver now depends on the ID assigned by the
SPI bus lock, the configuration field is deprecated.
The issue is introduced in 571864e8aeba85b941133766601543e0decd0faf. The
esp_flash API tries to clear the QE bit when the flash is not working in
quad modes.
However this introduces a regression, compared to earlier versions and
the legacy API. When the chip is not detected, the generic chip driver
is used, which cannot 100% handle the QE bit properly for all flash
vendors. There may be some flash chips (e.g. MXIC) that can be used in
dual modes by legacy API, but output wrong data when the esp_flash API
clears the QE bit in a wrong way.
This commit reverts the QE force clearing behavior, so that it's safer
for the generic chip driver to work under dual modes.
For url redirection cases (HTTP status 301/302), internal
transport ssl connection state must be reinitialized for
successful (new) connection on updated url.

Previous implementation violated the RFC by having both the actual opcode and WS_FIN flag set for all fragments of a message.
Fixed by setting the opcode only for the first fragment and WS_FIN for the last one
