Remove extern keywords from function prototypes and wrap long lines.

Use target_to_armv7a() etc, replacing needless pointer traversals.
Stop using X->arch_info scheme in most ARMv7-A and Cortex-A8 code.

Provide a cleaner way to handle single inheritance of targets
in C, using the same model Linux does: structs containing other
structs, un-nested via calls to a "container_of()" macro that
are packaged in typesafe inline functions.
Targets already use this containment idiom, but make it much
more complicated because they un-nest using embedded "void *"
pointers ... in chains of up to five per target, which is all
pure needless complication. (Example: arm92x core, arm9tdmi,
arm7_9, armv4_5 ... on top of the base "target" class.)
Applying this scheme consistently simplifies things, and gets
rid of many error-prone untyped pointers. It won't change any
part of the type model though -- it just simplifies things.
(And facilitates more cleanup later on.)
Rule of thumb: where there's an X->arch_info void* pointer,
access to that pointer can and should be removed. It may be
convenient to set up pointers to some of the embedded structs;
and shrink their current "*_common" names (annoyingly long).

previous
nonfunctional cortex_a8 code with something that at least basically
works (for halt/step/resume, without MMU) even if it is incomplete.
(With tweaks from Øyvind, and cleanup from Dave.)
This code has mainly been developed and tested against R1606, it has
been built and tested against R2294 where it runs but step and resume
commands are broken due to regression (which should be fixed now).
This code is really written for OMAP3530. It doesn't identify debug
resources using generic DAP calls to scan the ROM table, or perform
topology detection. The OMAP3530 DAP exposes two memory access ports:
- Port #0 is connected to L3 interconnect (the main bus) with
passthrough to the L4 EMU bus ... so it will be used for most
memory accesses.
- Port #1 is connected to a dedicated debug bus (L4 EMU), with
access to L4 Wakeup, and holds the ROM table ... so it must
be used for most debug and control operations.
The are some defines to handle this in cortex_a8.c, which should be
replaced with more general code. Having access to another Cortex-A8
implementation would help get that right.
