The only remaining user is arm7_9 so remove it from the target API and add
it to struct arm7_9_common to support all its variants with minimal
changes. Many of the variants are likely not correct in the cache/mmu
handling when the bulk write is triggered. This patch does nothing to
change that, except for arm946e, where it was easier to do what might be
the right thing.

The File I/O remote protocol extension allows the target to use the
host's file system and console I/O to perform various system calls.
To use the function, targets need to prepare two callback functions:
* get_gdb_finish_info: to get file I/O parameters from target
* gdb_fileio_end: pass file I/O response to target
As target is halted, gdb_server will try to get file-I/O information
from target through target_get_gdb_fileio_info(). If the callback function
returns ERROR_OK, gdb_server will initiate a file-I/O request to gdb.
After gdb finishes system call, gdb will pass response of the system call
to target through target_gdb_fileio_end() and continue to run(continue or step).
To implement the function, I add a new data structure in struct target,
called struct gdb_fileio_info, to record file I/O name and parameters.
Details refer to GDB manual "File-I/O Remote Protocol Extension"

In GDB remote serial protocol, the stop reply packet could contain more
detail stop reason. The currently defined stop reasons are listed below.
* watch
* rwatch
* awatch
* library
* replaylog
This commit adds stop reason, watch/rwatch/awatch, in stop reply packet for
just hit watchpoint. As manual indicates, at most one stop reason should be present.
The function needs target to implement new hook, hit_watchpoint. The hook will fill
the hit watchpoint in second parameter. The information will assist gdb to locate
the watchpoint. If no such information, gdb needs to scan all watchpoints by itself.
Refer to GDB Manual, D.3 Stop Reply Packets

On supported targets, this may be used to start a long running algorithm in
the background so the target may be interacted with during execution and
later wait for its completion.
The most obvious use case is a double buffered flash algorithm that can
upload the next block of data while the algorithm is flashing the current.

if polling is off, then "reset run + halt" would fail
since halt incorrectly assumed the target was in the
reset state as it is the internal poll implementation
that moves the sw tracking of the target state out
of the reset state.
To reproduce:
> reset run; halt
JTAG tap: zy1000.cpu tap/device found: 0x1f0f0f0f (mfg: 0x787, part: 0xf0f0, ver: 0x1)

For some reason there are *two* schemes for interposing logic into
the run_algorithm() code path... One is a standard procedural wapper
around the target method invocation.
the other (superfluous) one hacked the method table by splicing
a second procedural wrapper into the method table. Remove it:
* Rename its slightly-more-featureful wrapper so it becomes
the standard procedural wrapper, leaving its added logic
(where it should have been in the first place.
Also add a paranoia check, to report targets that don't
support algorithms without traversing a NULL pointer, and
tweak its code structure a bit so it's easier to modify.
* Get rid of the superfluous/conusing method table hacks.
This is a net simplification, making it simpler to analyse what's
going on, and then interpose logic . ... by ensuring there's only one
natural place for it to live.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "types.h"
the following form should be used.
#include <helper/types.h>

Switch "mrc" and "mcr" commands to be toplevel ARM operations,
as they should initially have been.
Correct the usage message for both commands: it matches ARM
documentation (as one wants!) instead of reordering them to
match the funky mrc() and mcr() method usage (sigh).
For Cortex-A8: restore a line that got accidentally dropped,
so the secure monitor mode shadow registers will show again.

In target_type.h it's documented that the target must be
halted for add_breakpoint() ... and with slight ambiguity,
also for its add_watchpoint() sibling. So rather than
verifying that constraint in the CPU drivers, do it in the
target_add_{break,watch}point() routines.
Add minor paranoia on the remove_*point() paths too: save
the return value, and print it out in in the LOG_DEBUG message
in case it's nonzero.
Note that with some current cores, like all ARMv7 ones I've
looked at, there's no technical issue preventing watchpoint or
breakpoint add/remove operations on active cores. This model
seems deeply wired into OpenOCD though.
ALSO: the ARM targets were fairly "good" about enforcing that
constraint themselves. The MIPS ones were relied on other code
to catch such stuff, but it's not clear such code existed ...
keep an eye out for new issues on MIPS.

There are two names that may matter on a per-target basis.
One is a per-instance name (for example, "at91sam7s.cpu").
The other is the name of its type (for example, "arm7tdmi"),
which is shared among multiple targets.
Currently target_get_name() returns the type name, which is
misleading and is rarely appropriate for target diagnostics.
Rename that as target_type_name().

Uses chaining of command_registration structures to eliminate all
target_type register_callback routines. Exports the command_handler
registration arrays for those target types that are used by others.

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.

This patch introduced a bug preventing flash writes from working
on Cortex-M3 targets like the STM32. Moreover, it's the wrong
approach for handling no-MMU targets.
The right way to handle no-MMU targets is to provide accessors
for physical addresses, and use them everywhere; and any code
which tries to work with virtual-to-physical mappings should use
a identity mapping (which can be defaulted).
And ... we can tell if a target has an MMU by seeing if it's
got an mmu() method. No such methood means no MMU.
