The build fails with crypto backends other than builtin, the
initializers cannot be reached as they're ifdef-ed out. Move
hash_init_accel under the right condition and delete the
algorithm-specific initializers as they're used only by the hash test
and that can simply call hash_init_accel to set the implementation.
All the -m flags need to be detected at configure time and the flag used
for ifdef (HAVE_CFLAG_m*), not the actual feature defined by compiler as
the dispatcher function is not built with the -m flags.
The uname check for x86_64 must be dropped so on i386/i586 we can still
build accelerated version.

The crc32c selection has been already using the pointer-based approach
so drop the cpuid detection and use our common code for that.

Change how sha256 implementation is selected. Instead of an if-else
check in the block processing function select the best version and assign
the function pointer. This is slightly faster.
At this point the selection is not implemented properly in
hash-speedtest so all results are from the fastest version. This will
be fixed once all algorithms are converted.

Change how blake2 implementation is selected. Instead of an if-else check
inside blake2b_compress each time, select the best one and assign the
function pointer. This is slightly faster.

Prepare a single location that will detect or set accelerated versions
of hash algorithms. Right now it's the crc32c, blake2 and sha256 do
an if-else switch while crc32c sets a function pointer.

Add the GPL v2 header to files where it was missing and is not from an
external source, update to the most recent version with the address.

Add definition, crypto wrappers and support to mkfs for blake2 for
checksumming. There are 2 aliases either blake2 or blake2b.

Add the definition to the checksum types and let mkfs accept it.
