stepping over an instruction that triggered a watchpoint.
* remote-mips.c: Numerous changes to support hardware breakpoints
and watchpoints on LSI MiniRISC and TinyRISC boards.
* mips-tdep.c: Move MIPS16-related macros to config/mips/tm-mips.h.
(mips_breakpoint_from_pc): Account for different breakpoint
instructions used by PMON and IDT monitor.
* config/mips/tm-embed.h: Enable hardware breakpoints on embedded
MIPS targets.
* config/mips/tm-mips.h: Define breakpoint instructions for
PMON and IDT monitor. Move MIPS16-related macros here from
mips-tdep.c.
for all mips*-*-ecoff or elf configurations.
* configure: Regenerate using autoconf 2.4.
* config/mips/{idt*.mt,tm-idt*.h}: Rename to "idt" part of the
name to "embed". Build remote-array.o along with IDT protocols.
* remote-array.c: Nuke setting the serial port to 4800 baud.
