As for complementary fips.c modification. Goal is to ensure that
FIPS_signature does not end up in .bss segment, one guaranteed to
be zeroed upon program start-up. One would expect explicitly
initialized values to end up in .data segment, but it turned out
that values explicitly initialized with zeros can end up in .bss.
The modification does not affect program flow, because first byte
was the only one of significance [to FINGERPRINT_premain].

Special note about additional -pie flag in android-armv7. The initial
reason for adding it is that Android 5 refuses to execute non-PIE
binaries. But what about older systems and previously validated
platforms? It should be noted that flag is not used when compiling
object code, fipscanister.o in this context, only when linking
applications, *supplementary* fips_algvs used during validation
procedure.

Normally it would be generated from a perlasm module, but doing so
would affect existing armv4cpuid.S, which in turn would formally void
previously validated platforms. Hense separate module is generated.

This is achieved by filtering perlasm output through arm-xlate.pl. But note
that it's done only if "flavour" argument is not 'void'. As 'void' is
default value for other ARM targets, permasm output is not actually
filtered on previously validated platforms.

While ARMv7 in general is capable of unaligned access, not all instructions
actually are. And trouble is that compiler doesn't seem to differentiate
those capable and incapable of unaligned access. As result exceptions could
be observed in xts128.c and ccm128.c modules. Contemporary Linux kernels
handle such exceptions by performing requested operation and resuming
execution as is if it succeeded. While on iOS exception is fatal.
Correct solution is to let STRICT_ALIGNMENT be on all ARM platforms,
but doing so is in formal conflict with FIPS maintenance policy.

X9.31 tests need to look in files for '9.31'
RSA-PSS tests may contain additonal text as well as "salt len: n".
We now just look at the start of a filename for a match.

Separate ECDSA2 test list.

Reorder test to handle new formats: for example PQGVer for DSA2 can be
detected based on file format but if this fails revert to PQGVER.

For future debugging add a --debug-detect option which prints out more
details of the test detection including the first few lines of each
request file.
