* monitor.h,monitor.c:
Added monitor flags MO_NO_ECHO_ON_SETMEM (don't expect echo on
setmem command), MO_RUN_FIRST_TIME (if command to start process
running on target is different from one to continue execution),
MO_HEX_PREFIX (if addresses from monitor have a "0x" prefix).
* monitor.c,parse.c,sparc-tdep.c:
Don't require strings in the registers array. This is to allow
NULLs to be place holders in the tm-*.h file so that only minor
changes are needed when a new processor is introduced (eg, one
without floating point).
* sparc-tdep.c: Conditionally remove dependancies on floating point.
* sparclet-rom.c,config/sparc/sparclet.mt,config/sparc/tm-sparclet.h:
New files for target sparclet.
* symfile.c: Add option for 2nd parameter on load command : a load
offset added to the vma of each section.
