ARM: "armv4_5" command prefix becomes "arm"
Rename the "armv4_5" command prefix to straight "arm" so it makes
more sense for newer cores. Add a simple compatibility script.
Make sure all the commands give the same "not an ARM" diagnostic
message (and fail properly) when called against non-ARM targets.

fileio: improve API types
Use size_t instead of uint32_t when specifying file sizes. Update all
consumers up through the layers to use size_t when required. These
changes should be safe, but the higher-levels will need to be updated
further to receive the intended benefits (i.e. large file support).
Add error checking for fileio_read and file_write. Previously, all
errors were being silently ignored, so this change might cause some
problems for some people in some cases. However, it gives us the chance
to handle any errors that do occur at higher-levels, rather than burying
our heads in the sand.

ARM: standard disassembler uses Thumb2 entry
Tweak "standard" ARM disassembler diagnostics to fail if the target
is not "an ARM" (vs. not "an ARMV4/5"), so it makes more sense for
cores inheriting this as the "generic" disassembler.
Also, to use the Thumb2 entry instead of the original Thumb entry.
This makes it work better for both newer cores (which support those
added instructions) and for BL and BLX instructions on older cores.
(Those instructions are 32-bits, which requires curious state-aware
code to go through a 16-bit decode interface...)
Plus minor cleanups, notably to have fewer exit paths and to make
sure they all return failure codes.
