* breakpoint.c (update_watchpoint): Change between software and
hardware watchpoint for all kinds of watchpoints, not just
read/write ones. Determine b->exact value here instead of
in watch_command_1. Error out if there are not enough resources
for a read or access hardware watchpoint.
(watch_command_1): Remove logic of checking whether there are
enough resources available, since update_watchpoint will do that
work now. Don't set b->exact here. Catch exceptions thrown by
update_watchpoint and delete the watchpoint.
(can_use_hardware_watchpoint): Remove exact_watchpoints argument.
Use target_exact_watchpoints instead.
(delete_breakpoint): Notify observers only if deleted watchpoint
has a breakpoint number assigned to it.

It turns out that this change is not correct, and it causes a crash
on sparc-solaris while trying to load ld.so. This is because the
memory is actually still referenced after elf_symtab_read completes.
gdb/ChangeLog:
* elfread.c (elf_symtab_read): Revert the previous change
that tried to stop a memory leak.

@value{GDBN} should be used in place of GDB, so this patch fixes it.

This change removes the dedication of the manual to Fred Fish.
