near where we read the pc to avoid erroneously setting
random_signal for multi-threaded support.

outside of #ifdef conditionals. Don't trash the wait status
if we get a signal and the current instruction is nullified.
Fixes long standing problem on the PA (spurious SIGTRAPs)..
* breakpoint.c (breakpoint_re_set_one): Keep temporary
breakpoints bp_until, bp_finish, bp_watchpoint_cope, bp_call_dummy
and bp_step_resume in case breakpoint_re_set_one is called due

inferior in BPSTAT_WHAT_CHECK_SHLIBS case.
* infrun.c (wait_for_inferior): Remove breakpoints and
switch terminal settings before calling SOLIB_ADD.
* solib.c (enable_break, SVR4 variant): Don't map in symbols
for the dynamic linker, the namespace pollution causes real
problems.
All references changed.
* breakpoint.c (bpstat_what): Add shlib_event to the class types.
Update state table. Reformat so that it's still readable.
When we hit the shlib_event breakpoint, set the calss of shlib_event.

to a shared library event.
(_initialize_infrun): Add new set/show variable "stop_on-solib-events"
to control whether or not gdb continues the inferior or stops it when
a shared library event occurs.
* minsyms.c (lookup_minimal_symbol_solib_trampoline): New function.
* somsolib.c (TODO list): Update.
(som_solib_create_inferior_hook): Arrange for gdb to be notified
when significant shared library events occur.
* hppa-tdep.c (find_unwind_entry): No longer static.
First cut at the machine independent changes for 7363. Also includes
