target: don't implicitly include "algorithm.h"
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.

ARM11: use now-generic memory utils
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.

ARM11: fixup method table
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

ARM: memory utils aren't ARM7/ARM9 dependent
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.

target: make "examined" flag be per-target
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.

target.cfg: label ETBs correctly
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).
