The hwseq_data struct remains to be a stack allocated
instance for now however it is referenced in the opaque_master
data field of the flash ctx. This allows for worker functions
that leverage hwseq_data state to derive state indirectly via
the flash ctx instead of directly upon the global state.
This allows for unblocking further work to finally dispense
with the stack allocation in favour of a heap allocation with
a defined life-time of the driver.

This is usefull for environments where the ich_descriptors_tool is not

crossystem uses flashrom to gather data on some platforms. To avoid
firmware lock deadlock, call crossystem before initialising libflashrom.
When querying hardware write protect status, provide an argument to
crossystem so that only that field is queried. This also avoids the
deadlock, and improves performance.

Write a newline after the hardware write protect prompt. Automated tests
read stdout and wait for this message, and split on newline, so write a
newline.
Also modify the function to not be recursive. Try to handle a closed
input correctly - panicing in that case. Behaviour is now to wait for
a newline instead of for 1 character.

Depend exclusive on the cmocka package provided by the build

systems. Besides that, it is suboptimal to fetch own dependencies in the
build process. Most packaging systems even forbid fetching additional
