There's no reason to read which interrupts are enabled from
the NVIC; that state isn't used. Plus, it's highly dynamic
since firmware can change it at any time; remove the support
for those state records.
Remove duplicate definition of DWT_CTRL address; shrink a line.

Fix the watchpoint error checks, and do them in add(), not later
in set() when it's mostly too late. Support the full range of
watchpoint sizes (1 to 32K bytes each), and check alignments.
Minor cleanup of DWT access: shrink lines, use "+" for address
calculations, comment a few issues. Add debug message reporting
DWT capabilities, matching the message for FBP, and some minor
code and spec review comments.

Add Doxygen for the exported ARMv7-M interfaces.

Add comment about a small speedup that the run_algorithm()
logic could use. Shrink a few too-long lines.

improve default target->read/write_phys_memory, produce
more sensible error messages if the mmu interface
functions have not been implemented yet vs. will
not be implemented(e.g. cortex m3).

The quit entry point was not being invoked. Just a source
of confusion at this point. XScale ran 100x reset upon
quit, but that code made no sense, wasn't commented
and never invoke.

Config for Intel's "Lubbock" PXA255 development board. Even more
so than the PXA255 itself, this is obsolete. AFAIK this was the
first generally available development platform for PXA255. Intel
stopped providing these after other devel boards became available.
One interesting thing about this board from the OpenOCD perspective
is probably its flash configuration. Each bank is 32 bits wide,
built from two 16-bit StrataFlash chips wired in parallel. This
doubles throughput ... it reads/writes 32 bits in the time a single
chip takes to write just 16 bits.
This conf mostly works, given XScale bugfixes, but has some issues
(notably: no access to the on-board SDRAM) flagged by FIXMEs.

We currently do something unusual: version codes in config.in get
updated after the release, which means that "git describe" won't
match up to development version labels. Comment that trouble spot.
We can fix this by switching away from the major/minor/micro type
release numbering, as various other projects have done. The major
numbers basically don't tend to change, and doing a good job with
micro versions is so annoying that they rarely change either.

Contrast releases to git snapshot tarballs. Mention that
releases have some quality-improvement focus, with special
non-"dev" version IDs. Explain more about version IDs,
using "openocd -v" to see them, etc;
Make release milestone info be less specific about timing,
and presume we have both a merge window and an RC stage.
Rework the release process information to match reality a
bit more closely. Reference the version.sh script (in one
place the wrong script was referenced). Bugfix branches
get special treatment, while non-bugfix releases are more
or less what *defines* being the mainline branch.

The "source" command isn't accepted by ASH; easy to fix.
Failures with "-e" are harder to fix. Remove the "-e"
(for now) and force bash, for safety.
Un-obfuscate the release steps, by using names instead
of numbers. Comment the version-number manipulation.

Fixed bug: if virtual address for working memory was not specified
and MMU was enabled, then address 0 would be used.
Require working address to be specified for both MMU enabled
and disabled case.
For some completely inexplicable reason this fixes the regression
in svn 2646 for flash write in arm926ejs target. The logs showed
that MMU was disabled in the case below:

For some reason, all the interals are documented by default.
This is wrong for two basic reasons:
- We need to focus on public interfaces, since those are
the architectural interfaces and relationships.
- Since virtually nothing has doxygen support yet, this
maximizes the noise, and minimizes the usefulness of
doxygen output.
So don't expose so much by default.

Implement XSVF support for detailed state path transitions,
by collecting sequences of XSTATE transitions into paths
and then calling pathmove().
It seems that the Xilinx tools want to force state-by-state
transitions instead of relying on the standardized SVF paths.
Like maybe there are XSVF tools not implementing SVF paths,
which are all that we support using svf_statemove().
So from IRPAUSE, instead of just issuing "XSTATE DRPAUSE"
they will issue XSTATES for each intermediate state: first
IREXIT2, then IRUPDATE, DRSELECT, DRCAPTURE, DREXIT1, and
finally DRPAUSE. This works now.
Handling of paths that go *through* reset is a trifle dodgey,
but it should be safe.

Only the Feroceon code builds on this, so only routines it
reuses should be public.. Make most remaining functions
static, and fix some of the line-too-long issues.

The Hex parser uses a fixed number of sections. When the
number of sections in the file is greater than that, the
stack get corrupted and a CHECKSUM ERROR is detected
which is very confusing.
This checks the number of sections read, and increases
IMAGE_MAX_SECTIONS so it works on my file.

A '.*' rule prevents the 'git submodule add' from correctly adding the
first submodule, because it creates the .gitmodule file. This file will
not be added (without -f) result in incomplete submodule commits.
The new rules mask the specific files present in my own build tree, but
additional rules may be needed to hide other types of temporary files.
