In preparation for conditionally supporting SVE we need to be able to
have different sized reginfos. This introduces reginfo_size() to
abstract the size away to the code the actually knows. For aarch64 we
also use this while initialising the block.

Allows the backend to do more that just set a flag when it comes to
processing options.

The key variables here are: *arch_long_opts and *arch_extra_help. If
they are not NULL then we concatenate the extra options to appropriate
structure to enable the support. Adding architecture short options is
not supported.
This also includes moving the ARM specific test_fp_exc/test-fp-exc
into ARM specific code.

Move an orphan comment that describes the reginfo structure
into risu.h, and expand it a little.

The code in reginfo_init_vfp() to parse the signal frame
was mishandling the size counts:
* the size includes the bytes for the magic and size fields,
so the code to skip forward over unknown or undersize blocks
was adding 4 more than it should
* the size is in bytes but the "is this block too small"
test was checking against an expected size in words
This didn't cause any problems because the kernel happens
to generate signal frames with the VFP section first.

This is pretty much a mechanical change where I ran:
indent -kr
Across all the files and then fixed up all but a few violations of:
../../qemu.git/scripts/checkpatch.pl -f *.c *.h > checkpatch.out
Along with heavy use of M-x untabify to make everything consistent.

put the struct reginfo and its methods in a separate module.
This also addresses the problem with the memcmp
being used directly on the struct without the memset 0.
