Observed:
openocd: core.c:318: jtag_checks: Assertion `jtag_trst == 0' failed.
The issue was that nothing disabled background polling during calls
from the TCL shell to "jtag_reset 1 1". Fix by moving the existing
poll-disable mechanism to the JTAG layer where it belongs, and then
augmenting it to always pay attention to TRST and SRST.

- 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.

- don't needlessly export this function
- handle "case 0" debug method-of-entry better (silent by default)
The "case 0" is a valid debug entry mode so it doesn't deserve the
warning int now gets. But it probably means that OpenOCD confused
itself somehow; or that it confused the ARM9EJS target.

- ETB
* report _actual_ hardware status, not just expected status
* add a missing diagnostic on a potential ETB setup error
* prefix any diagnostics with "ETB"
- ETM
* make "etm status" show ETM hardware status too, instead of
just traceport status (which previously was fake, sigh)
- Docs
* flesh out "etm tracemode" docs a bit
* clarify "etm status" ... previously it was traceport status
* explain "etm trigger_percent" as a *traceport* option
ETM+ETB tracing still isn't behaving, but now I can see that part of
the reason is that the ETB turns itself off almost immediately after
being enabled, and before collecting any data.

- Commands were supposed to have been "arm11 memwrite ..."
not "memwrite ..."
- Get rid of obfuscatory macros
- Re-alphabetize
- Add docs for "arm11 vcr"

only expose the registers which are actually present. They
could be missing for two basic reasons:
- This version might not support them at all; e.g. ETMv1.1
doesn't have some control/status registers. (My sample of
ARM9 boards shows all with ETMv1.3 support, FWIW.)
- The configuration on this chip may not populate as many
registers as possible; e.g. only two data value comparators
instead of eight.
Includes a bugfix in the "etm info" command: only one of the
two registers is missing on older silicon, so show the first
one before bailing.
Update ETM usage docs to explain that those registers need to be
written to configure what is traced, and that some ETM configs
are not yet handled. Also, give some examples of the kinds of
constrained trace which could be arranged.

system, removes 20 non-existent registers ... but still includes
over 45 (!) ETM registers which don't even exist there ...
- Integrate the various tables to get one struct per register
- Get rid of needless per-register dynamic allocation
- Double check list of registers:
* Remove sixteen (!) non-registers for data comparators
* Remove four registers that imply newer ETM than we support
* Change some names to match current architecture specs
- Handle more register info
* some are write-only
* some are read-only
* record which versions have them, just in case
- Reorganize the registers to facilitate removing the extras
* group e.g. comparator/counter #N registers together
* add and use lookup-by-ID

- Add a header comment
- Line up the ETM context struct, pack it a bit
- Remove unused context_id (this doesn't support ETMv2 yet)
- Make most functions static
- Remove unused string table and other needless lines of code
- Correct "tracemode" helptext
Also provide and use an etm_reg_lookup() to find entries in the ETM
register cache. This will help cope with corrected contents of that
cache, which doesn't include entires for non-existent registers.

- Shrink messaging during resets, primarily by getting rid of
"nothing happened" noise that hides *useful* information.
- Improve: the "no IDCODE" message by identifying which tap only
supports BYPASS; and the TAP event strings.
Related minor code updates:
- Remove two needless tests when examining the chain: we know
we have a TAP, and that all TAPs have names.
- Clean up two loops, turning "while"s into "for"s which better
show what's actually being done.

and Tcl/external):
- Reorder so *both* paths (TCK/TMS or TRST) can enable TAPs with
ICEpick ... first C code flags TAPs that got disabled, then call
any Tcl code that might want to re-enable them.
- Always call the C/internal handlers when JTAG operations can be
issued; previously that wasn't done when TRST was used.
Plus some small cleanups (whitespace, strings, better messaging
during debug and on some errors) to reset-related code.

- update comments to say so.
- update docs to clarify that the "arm9tdmi" command prefix
is a misnomer.
- bugfix some messages that wrongly assume only ARM9TDMI
based processors use this code.

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)
