[ Upstream commit 7b3c2348d314a18f6ed84bab67023ae5d1ec6b1e ]
Some of the tests for unfused parts referenced a named member parameter,
but when the test suite was switched to call a python ctypes library they
weren't updated. Adjust them to refer to the first argument of the
process_param() call and set the data type of the signature appropriately.

[ Upstream commit 2ad01eb5fad24627ab4e196dc54a220753b2238b ]
When parameters are sent the PSP returns back it's own signature
for the application to verify the authenticity of the result.
Display this signature to the caller instead of the one the caller
sent.

[ Upstream commit 70f242c1933e9e881c13c31640bb6d56e8b7e738 ]
The sample application was taking values from ioctl() and treating
those as the error codes to present to a user.
This is incorrect when ret is non-zero, the error is stored to `errno`.
Use this value instead.

[ Upstream commit 7f71c3e033824e1da237916a1885e3c0699f86b2 ]
A local environment change was importing ioctl_opt which is required
for ioctl tests to pass. Add the missing import for it.

Interacting with dynamic boost control messages requires the caller
to supply a signature. To allow validation of individual dynamic
boost control components, introduce a set of tests that can be run.
The tests can be run in 3 distinct different environments, and so
certain tests will be skipped depending on the environment.
1. Systems that do not support DBC.
2. Production systems that support DBC but are secured silicon.
3. Pre-production systems that support DBC but are unsecured silicon.
Unsecured silicon does not validate the signature, and so this allows
testing more of the state machine and functionality.

Dynamic Boost Control commands are triggered by userspace with
an IOCTL interface that userspace will prepare proper buffers
for a request.
To allow prototyping and testing this interface, add a python3
command line script that loads the dbc_library.so for utilizing
the IOCTLs.
The signature to use and UID are passed as arguments to this script.

The directory tools/crypto and the only file under it never gets
built anywhere. This program should instead be incorporated into
one of the existing user-space projects, crconf or libkcapi.

Since now all crypto stats are on their own structures, it is now
useless to have the algorithm name in the err_cnt member.
