Magnus Lundin <lundin@mlu.mine.nu>, Oyvind Harboe <oyvind.harboe@zylin.com>, David Brownell <david-b@pacbell.net>: 

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.)
