Create a generic register_cache_invalidate(), and use it to
replace three all-but-identical core-specific routines:
- armv4_5_invalidate_core_regs()
- armv7m_invalidate_core_regs
- mips32_invalidate_core_regs() too.
Make cache->num_regs be unsigned, avoiding various errors.
Net code shrink and simplification.

Removing the fast command eliminates the fast_and_dangerous global,
which was used only by arm7_9_common as an initializer. The command
is not called in the tree; instead, more explicit commands are used.
The jim_global_long function was not used anywhere in the tree.
Updates all command parsing of simple "enable" and "disable" arguments.
A few case in the tree use a tri-state or extended arguments, which
cannot use this simple macro.
Simlifies the xscale icache/dcache command handler logic.
Add a new is_arm_mode() predicate, and use it to replace almost
all calls to current armv4_5_mode_to_number().
Eventually those internal mode numbers should vanish... along
with their siblings in the armv7a.c file.
Remove a handful of superfluous checks ... e.g. the mode number
was just initialized, or (debug entry methods) already validated.
Move one of the macros using internal mode numbers into the only
file which uses that macro. Make the tables manipulated with
those numbers be read-only and, where possible, static so they're
not confused with part of the generic ARM interface.

Add and use arm_mode_name() to map from PSR bits to user
meaningful names. It uses a new table which, later, can
be used to hold other mode-coupled data.
Add definitions for the "Secure Monitor" mode, as seen on
some ARM11 cores (like ARM1176) and on Cortex-A8. The
previous mode name scheme didn't understand that mode.
Remove the old mechanism ... there were two copies, caused
by Cortex-A8 needing to add "Secure Monitor" mode support.

Don't include it in more headers than necessary; just
use it in the few files that actually need it.

Same deal: "register.h" got needlessly included all over the
place because of being in a few widely included headers.
So take it out of the header files which included it, and put
it in files which use it ... reduce needless interdependencies.
Also, don't need that extra "types.h" inclusion.

Most files in the tree seem to have ended up including this,
and *quite* needlessly ... only code implementing or using
downloadable algorithms actually needs these declarations.
So take it out of the header files which included it, and put
it in files which use it ... reduce needless interdependencies.
Also: "algorithm.h" doesn't need to include "types.h" again;
it already comes from a different header.

The arm7_9_checksum_memory() and arm7_9_blank_check_memory()
routines are not actually specific to the ARM7 and ARM9 core
generations ... they can work for any core which can run
algorithms using basic ARM (not Thumb) instructions.
Rename them; move the declarations to a more generic site;
likewise move the code (and tidy it a bit in the process).
NOTE: the blank_check() method falsely returned a success
status (0) on one error path, when the algorithm failed.
Fixed this bug.

No point in having two identical examine methods for the
ARM7TDMI and ARM9TDMI drivers; move, rename, shrink, share.
Add a bit of doxygen; stop needlessly exporting a method.

Remove the last external user of arm7_9_get_arch_pointers(), and
that annoying downcast utility. Add an is_arm7_9() predicate.
Stop returning specious success codes on various failure paths
in the ARM7/ARM9 commands which used that downcast utility.

Various cleanups of ETM related code.
- Saner error return paths
- Simplify arm7_9 init ... no need for extra zeroing!
- Shrink some lines
- Tweak some diagnostics
- Use shorter name for ETM struct type.
- Don't exit()
and similar. The diagnostics look forward to having
this ETM code work with more than just ARM7/ARM9.

It's been about a year since these were deprecated and, in most
cases, removed. There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever. (Or a few remnants of obsolete code...)
Removed a few obsolete uses of "jtag_speed":
- The Calao stuff hasn't worked since July 2008. (Those Atmel
targets need to work with a 32KHz core clock after reset until
board-specific init-reset code sets up the PLL and enables a
faster JTAg clock.)
- Parport speed controls don't actually work (tops out at about
1 MHz on typical HW).
- In general, speed controls need to live in board.cfg files (or
sometimes target.cfg files), not interface.cfg ...

- revert to previous default: don't talk JTAG during SRST
- add "srst_nogates" flag, the converse of "srst_gates_jtag"
- with no args, display the current configuration
And update the User's Guide text with bullet lists to be a bit more clear.

Cleanup some the downloaded ARM target algorithm code:
- Provide more complete disassembly of the DCC bulk write code
- Make code blocks "static const", in case GCC doesn't
- Fix some tabbing/layout issues
- Make some arm7_9_common.h flags be "bool" not "int"; and compact
the layout a bit (group most bools together)
