Usage syntax messages have the same EBNF as the User's Guide.
Don't use "&function"; functions are like arrays, their address
is their name. Shrink some overlong lines; remove some empties.

to be more accurate (mostly they display something w/no args).

In some cases, *exactly* what the user's guide shows... e.g.
talking about "offset" not "address" for trace_image.
Don't use "&function"; functions are like arrays, their name
is their address.

Don't save that state unless its only user, an assertion,

Starting the daemon with with just a bare "openocd" I saw:
Can't find openocd.cfg
That's not an error; don't treat it as if it were. There may
be an error later -- like, "no interface set up" -- but let
messages only report real errors, not fake ones.
JTAG has only two possible JTAG ack codes for APACC and DPACC
register reads/writes. Define them, and remove empty "else"
clause in the code which now uses those codes.

I think some of these assumptions are not well-founded.
Related, that swjdp_transaction_endcheck() is a bit iffy.

The gdb_port command can be invoked during normal execution
to report the port used for gdb, whereas it was listed as
CONFIG stage only, which caused an error when excuting
it to return the reported error.
Also in line with the grander goal of making more commands
available during all "modes" (perhaps retiring config mode),
there is no particular reason to limit gdb_port to the
config stage.

Add doxyegen description for this driver.
Correct the helptext (configures *or* displays based on #params),
and usage (use the same BNF as the User's Guide).

The command processing conversion a while back lost the
"rtck" enable/disable command; restore it.
NOTE that having such a command is wrong; there's a standard
way to enable adaptive clocking ("speed 0").

Build fixes: it failed abysmally with PPDEV enabled. Swapped
a build-time error with a FIXME comment in the affected macros.
Cleanup: remove "&" before function pointers, and excess indent,
for the interface struct declaration.

Rename DAP_IR_* as JTAG_DP_* since those symbols are specifically
for JTAG-DP (or SWJ-DP in JTAG mode), and won't work with SWD.
Define the JTAG ABORT and IDCODE instructions for completeness;
add a comment about where to (someday) use ABORT.
Fix messaging which assumes everything is an SWJ-DP; say "JTAG-DP"
instead, it's at least more appropriate for all JTAG transports.

Fix: don't print the BASE address except if it's a MEM-AP;
that's an unlikely error, but there's no point getting it wrong.

Make some private functions "static". Remove their public declarations,

Instead of magic numbers, use their AP_REG_* constants. Rename
the ROM address symbol as BASE to match ARM's documentation.
Comment various other symbols in the header; add some missing ones.
Remove an unused struct. Add some doxygen for stuff including the
DAP structure and initialization.
