The keymaster TA has 30841 distinct coverage counters, so 0x4000 counter
slots is not enough to handle this TA. Increase maximum number of
coverage counters to 0x8000.

Add an initial corpus for the keymaster fuzzer derived from running the
keystore2 unittests.

libtrusty can be depended on by multiple thing in a fuzzer's
dependencies tree. It's no longer convenient to link to statically.
Leave tests statically linked. Test infra doesn't seem to handle shared
test libs correctly.

Fix a typo in one of the short command line options
for the Trusty application loader. The typo caused
the tool to incorrectly accept the -s short option
and ignore it, but not accept the -D option which
is the short version of --dev.

The header SecureDPU.h is moved out from the device specific folder as
it can be shared for different devices.

Trusty Keymaster will currently disconnect the client on an invalid
message. This includes the newly introduced GET_VERSION2 message.
While in the future we could change this behavior, this is a backcompat
path and so we can't assume a changed Trusty. Reconnect on failed
GET_VERSION2 before attempting version negotiation.

* changes:
trusty: Add simple fuzzer for keymaster TA
trusty: Increase limit on coverage counters
trusty: Write out sancov file when fuzzer exits
trusty: Switch to dmabuf for coverage shared memory
Adds a simple libfuzzer-based coverage guided fuzzer for keymaster.
Current coverage is low, so we'll need to improve this with an initial
corpus or a more sophisticated protocol aware fuzzer.

Keymaster has more than 4096 counters, so we need to allocate a larger
section for the libfuzzer extra counters. Increases the size of the
extra counters section to 16384.

Add emission of sancov file when CoverageRecord is destroyed. This
will occur when a fuzzer driver exits cleanly, i.e. -runs=0 with an
existing corpus.

Trusty shared memory now uses dmabuf instead of memfd. Switch the
coverage buffer allocation to use libdmabufheap.

The corpus of Confirmationui usually contains multiple data packets
to be transfered from Android side to Trusty side.
Therefore we adjust the Confirmationui fuzzer so that it can send
data to Confirmationui TA several times through a same tipc channel.

We want to add coverage statistics to the trusty-ut-ctrl tool, which is
a vendor binary. Thus we need a vendor variant of libtrusty_coverage.
Merges system libtrusty_test and vendor libtrusty into a single
vendor_available library so that we can add vendor_available to
libtrusty_coverage and make it accessible from vendor tools.
