Rafal Redzimski 12b056600d ipc4: update ipc_cmd_hdr to fit largest ABI header
The ipc_cmd_hdr should have size no lesser that largest
of the headers amongst all ipc protocol versions.
The use of smaller type for ipc_cmd_header is unsafe because
of casting pointers between differently sized headers followed by
accessing data through incremented pointer.

Curtis Malainey a0acad3414 CMake: require version 3.13
Without CMP0079 we cannot conditionally include libraries against SOF in
sub directories without seriously restructuring the project. This is
because the old policy requires the link target must be created in the
same folder. This does not work well from a configuration standpoint for
3P audio libraries trying to keep their config in src/audio/*. Rather
than enable the policy, lets simply upgrade since 3.13 is widely
available.

With this upgrade we can also remove the two version dependent checks at
the top of our scripts.

Curtis Malainey 758e7be0c9 oss-fuzz: fix build
looks like with the new ipc mechanisms we changed the function signature
and moved casting the message from platform code to ipc code.

Liam Girdwood 517ad95d51 ipc: split ipc headers per function.
Split IPC APIs out by feature so that the IPC layer to help future
IPC infrastructure changes support more than one IPC ABI MAJOR version.

No code changes here, only code partitioning and Doxygen comments.

Marc Herbert 288e228c67 cmake: generate the complete .config at configuration time.
Add cmake -DINIT_CONFIG= option that can point at any initial file.

"make clean" does not delete .config any more.

Note reconfiguration does NOT causes recompilation because -imacros
hides the generated .h from CMake's dependency scan. This is not a
regression, that problems exists since -imacros was introduced. At least
it's now possible to "make clean" and rebuild without losing the .config
file.

Fix for #3617

Curtis Malainey 6823206761 oss-fuzz: add seed corpus
There are simply a dump of a series of messages from the kernel of
messages sent to the firmware. This will be used by the fuzzer to infer
inputs to tests against the the firmware.

Curtis Malainey 0a7df45e87 library: add trace and shared memory region
Trace is enabled by default for library builds, but the module is not
included. This breaks the ipc handler. Therefore lets include it and
give it a mocked section of memory to write to.

The fuzzer is makings its way into a lot places where we assume hw
configs exist. Therefore a refactor is needed make it easy to fill in

Curtis Malainey 1d028ab9c1 fuzz_ipc: use calloc instead of malloc for ipc region
The memory sanitzer catches uninitialized value errors on the size check
for small data sizes. Therefore lets us calloc so we can assume the
whole region exists without having the sanitizer get upset.
