Move various embedded target structs to the beginnings of
their containers ... pretty much the way C++ or Obj-C
would for single inheritance.
This shrinks code that accesses those embedded structs by
letting common offsets use smaller instructions. Sample
before/after sizes (on amd64):
17181 312 0 17493 4455 arm920t.o
16810 312 0 17122 42e2 arm920t.o
Where the "after" is the smaller number, with this patch
over the ones leveraging that embedding knowledge.

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).

Unneeded exports cause confusion about the module interfaces.
Make most functions static. Add a short header comment.
The forward decls are just code clutter; remove them, by moving
their references after definitions. This is another file which
never needed even one internal forward declaration.
This saved almost 900 bytes of code on x86_32; it seems the
compiler can leverage its knowledge that these functions are
not called from the outside world...

This is minimal patch to support FA526 ARMv4 compatible core.
Since it is very similar to ARM920T I tried to reuse as much
code as possible.
CPU and board configs will follow soon.

- Replace '\([^_]\)u32' with '\1uint32_t'.
- Replace '^u32' with 'uint32_t'.

broken on big-endian targets and/or hosts
- added access to ARM920T vector catch register (via generic register mechanism)
- don't disable linefills on ARM920T cores - this lead to lockups when accessing lines already contained in cache
- read content of ARM920T cache and tlb into file (arm920t read_flash/read_mmu commands)
- memory reading improved on ARM7/9, can be further accelerated with new "arm7_9 fast_memory_access enable" command (renamed from fast_writes)
- made in_handler independent from in field (makes the handler more flexible)
- added timeout to ft2232 when using D2XX library
- fixed STR7x protection bit handling on second bank (thanks to Bernard)
- added support for using the OpenOCD on AT91RM9200 systems (thanks to Anders Larsen)
- fixed AT91SAM7 flash handling when not running from 32kHz clock (thanks to Anders Larsen)
