The gdb script created by coredump-reader has a fixed reset
vector address. This address only works on a subset of supported
SOF platforms and for other platforms, user has to manually fix
the reset address in the gdb script before use.
Modify the script to emit breakpoint for "_MemErrorVector"
symbol. This is not the reset vector, but the simulation will
still be trapped early. The symbol is part of the firmware
binary, so its address can be looked up at runtime.
Also add a second breakpoint for "_MemoryExceptionVector_text_start".
This will cover SOF binaries built with Zephyr as the RTOS.

Introduce a new component to perform acoustic echo cancellation
on capture path using a buffer from the playback as a reference.
1. Put the google_rtc_audio_processing at
$SOF_REPO/third_party_libraries
- libgoogle_rtc_audio_processing.a
- libgoogle_rtc_audio_processing_tuning.a
- libc++.a (Corresponding stdlibc++)
- libc++abi.a
2. Put the header in $SOF_REPO/third_party_includes
- google_rtc_audio_processing.h
3. Build firmware and tool with xcc
4. To verify it works:
- aplay some speech
- At the same time arecord the mic which uses AEC
The mic signal should not exhibit any echo from the playback.

Add support for four max98357a speaker amplifiers running in TDM mode
which format is 8 slots with 32 bit slot/sample width on ADL boards.
The only difference between this one and sof-adl-max98360a-rt5682-4ch
is the SSP port for speaker amplifiers; this one is using SSP2 while
max98360a's topology is using SSP1.

Move generated *.conf and *.tplg v1 files down from:
build_tools/topology/topology1/*.{conf,tplg}
_to:
build_tools/topology/topology1/production/*.{conf,tplg}
... then copy/"install" the production/* subdirectory two levels up.
This fixes the race condition #5067 that also copied a random number of
development/ and dsp_enhancement/ topologies, sometimes even truncating
these.
In other words, this commit REMOVES the following two copies:
build_tools/topology/development/ # randomly corrupted copy, removed
build_tools/topology/dsp_enhancement/ # randomly corrupted copy, removed
build_tools/topology/topology1/development/ # real build dir, unchanged
build_tools/topology/topology1/dsp_enhancement # real build dir, unchanged
Production topologies are copied only to help with the v1->v2
transition. That duplication makes the build directory confusing enough,
no need to extend that copy to development topologies. A single instance
of development topologies in the build directory is enough.
This removal may break some CI script(s): this is perfect because such
CI script(s) were copying randomly corrupted data.

When the firmware receives a START or RELEASE IPC message, it
immediately triggers all involved components, which starts DMA.
Then it schedules the pipeline task, but since the scheduler can be
already running at that time, the task might be scheduled when DMA
data isn't available yet or has already overflowed. To fix this
change the control flow to also trigger all components from the task
during its first run. Actual data processing then begins with the
next period. Note, that this is currently only possible with
pipelines, using timer-based scheduling. Pipelines, using DMA
interrupts for scheduling are unaffected.
