User's Guide updates

Capture various bits of useful information that have come up on the
list but haven't yet gotten into the documentation:

 - Watchdog timers firing during JTAG debug need attention;

 - Some chips have special registers to help JTAG debug;

 - Cortex-M3 stepping example with IRQs and maskisr;

 - Clarifications re adaptive clocking:  not all ARMs do it, and
   explain it a bit better.

NOR: add optional "flash erase_address" sector padding

Add a NOR flash mechanism where erase_address ranges can be padded
out to sector boundaries, triggering a diagnostic:

  > flash erase_address 0x0001f980 16
  address range 0x0001f980 .. 0x0001f98f is not sector-aligned
  Command handler execution failed
  in procedure 'flash' called at file "command.c", line 647
  called at file "command.c", line 361
  >

  > flash erase_address pad 0x0001f980 16
  Adding extra erase range, 0x0001f800 to 0x0001f97f
  Adding extra erase range, 0x0001f990 to 0x0001fbff
  erased address 0x0001f980 (length 16) in 0.095975s (0.163 kb/s)
  >

This addresses what would otherwise be something of a functional
regression.  An earlier version of the interface had a dangerous
problem:  it would silently erase data outside the range it was
told to erase.  Fixing that bug turned up some folk who relied on
that unsafe behavior.  (The classic problem with interface bugs!)
Now they can get that behavior again.  If they really need it,
just specify "pad".

Cortex-M3: improved core exception handling

This updates three aspects of debugger/exception interactions:

 - Save the user's "vector_catch" setting, and restore it after reset.
   Previously, it was obliterated (rather annoyingly) each time.

 - Don't catch BusFault and HardFault exceptions unless the user says
   to do so.  Target firmware may need to handle them.

 - Don't modify SHCSR to prevent escalating BusFault to HardFault.
   Target firmware may expect to handle it as a HardFault.

Those simplifications fix several bugs.  In one annoying case, OpenOCD
would cause the target to lock up on ome faults which triggered after
the debugger disconnected.

NOTE:  a known remaining issue is that OpenOCD can still leave DEMCR
set after an otherwise-clean OpenOCD shutdown.
