      Optionally shave time off the armv4_5 run_algorithm() code:  let
them terminate using software breakpoints, avoiding roundtrips
to manage hardware ones.

Enable this by using BKPT to terminate execution instead of "branch
to here" loops.  Then pass zero as the exit address, except when
running on an ARMv4 core.  ARM7TDMI, ARM9TDMI, and derived cores
now set a flag saying they're ARMv4.

Use that mechanism in arm_nandwrite(), for about 3% speedup on a
DaVinci ARM926 core; not huge, but it helps.  Some other algorithms
could use this too (mostly flavors of flash operation).

      David Brownell <david-b@pacbell.net> Tweak disassembly commands: · bc075606
      oharboe authored 
       For ARMv4/ARMv5:
  - better command parameter error checking
  - don't require an instruction count; default to one
  - recognize thumb function addresses
  - make function static
  - shorten some too-long lines
 For Cortex-M3:
  - don't require an instruction count; default to one

With the relevant doc updates.
---
Nyet done:  invoke the thumb2 disassembler on v4/v5,
to better handle branch instructions.

      - Work on fixing erase check. Many implementations are plain broken.
Wrote a default flash erase check fn which uses CFI's target algorithm
w/fallback to memory reads. 
- "flash info" no longer prints erase status as it is stale. 
- "flash erase_check" now prints erase status. erase check can take a 
*long* time. Work in progress
- arm7/9 with seperate srst & trst now supports reset init/halt
after a power outage. arm7/9 no longer makes any assumptions
about state of target when reset is asserted.
- fixes for srst & trst capable arm7/9 with reset init/halt
- prepare_reset_halt retired. This code needs to be inside
assert_reset anyway
- haven't been able to get stm32 write algorithm to work. Fallback
flash write does work. Haven't found a version of openocd trunk
where this works.
- added target_free_all_working_areas_restore() which can
let be of restoring backups. This is needed when asserting
reset as the target must be assumed to be an unknown state.
Added some comments to working areas API
- str9 reset script fixes
- some guidelines
- fixed dangling callbacks upon reset timeout
