Don't include "target.h" from more headers than necessary.  This
avoids needless interdependencies and duplicated include paths.

Don't needlessly include it in source files, either.

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.

Lots of files still include it, often through needless
duplicate inclusion of "log.h"; sigh.

This cleans up the inclusion graph a bunch, so there are
fewer inclusion paths, but it doesn't change much otherwise.

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.

Now the ARM11 cores can use the renamed arm_checksum_memory()
and arm_blank_check_memory() routines ... do so.

Sanity checked with "flash erase_check" of both NOR banks on an
OMAP2420 ... the algorithm code dumped four lines of of "poll"
status after each of almost 520 blocks (yes, *very* annoying) but
gave plausible results after producing that spam.

Three changes:  remove ARM11_HANDLER() in favor of normal structure
initialization syntax; fix goofy indentation in that structure; and
don't needlessly export arm11_register_commands(), it's only called
through that method table.

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.

Previously this flag was stored in "target_type", so that for example
if there were two ARM7TDMI targets in a scan chain, both would claim
to have been examined although only the first one actually had its
examine() method called.

Move this state to where it should have been in the first place, and
hide a method that didn't need exposure ... the flag is write-once.

Provide some doxygen.  The examine() method is confusing, since it
isn't separating one-time setup from the after-each-reset stuff.  And
the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug
state alone after reset ... probably more of an issue for trace setup
than for watchpoints and breakpoints.

These drivers were overlooked during the recent upgrade.  Convert them,
moving their registration routines to eliminate their declarations.

Fix an instance where my cleanup when awry.

Removes unused arm_jtag_buf_* helpers from arm_jtag.[ch].  These could
reappear if patches are provided to conver the tree to use them, but
this code should not be in the master tree until that series is ready.

Purge an unused routine from the tree and remove a layering violation.
If this code is needed, it should reappear somwhere in src/jtag/,
where struct scan_field gets defined.

Remove obsolete suffix from struct scan_field.  Somehow, these
definitions did not get updated but did not cause any errors.

This fixes an issue due to the new command handler syntax caused by the mw handler playing with the args pointer before
using the CMD_NAME macro.  Fix is to move this call above the lines changing args.

Create src/openocd.h to hold declarations previously made internally
by src/main.c and src/server/server.c.  This ensures all functions
are verified to be in-sync at compile time (rather than at link),
making it easier to track down bugs.

Changed some printf format strings..

Kick in ETM (and ETB) support for ARM11.  Tested on OMAP 2420,
so update that configuration.  (That's an ARM1136ejs, ETB,
OpenGL ES1.1, C55x DSP, etc.)

Also update the other ARM11 ETM + ETB targets in the tree
to set up these modules.  (Not tested.)

We have too many different registers, and too many version and
context dependent interpretations, for this type of bitfield
management to be scalable.

(Anyone who really wants bitfield interpretation *can* do that
in Tcl code...)

There are ... quite a few copies of the same ARM dummy registers.
There should eventually be one copy; this many is craziness.

Various cores with an ETB have its TAP misnamed ... either as a
boundary scan TAP or as the iMX "Secure JTAG Controller" (which
is, among other things, a JRC that could be used to shorten
scan chains).

Use the correct name for these TAPs, which we can recognize since
their IDs were assigned by ARM and these chips all document the
presence of an ETB.  The 0x2b900f0f is ETB11; the 0x1b900f0f
is an older module, just called "ETB".

Also shrink the ETB's IR configuration; the default IR-Capture
value is fine, and the mask can specify that all four bits are
safe to check (per ARM documentation).
