Move the dap command handler implementations to arm_adi_v5.c,
leaving just thin wrappers in armv7m.c.  There should be no
change in functionality here.  (From Magnus.)

Minor style cleanup:  whitespace, line length, etc.  Update spec
references to use docs which are currently available.  (From Dave.)
