* sol-thread.c (GET_LWP, GET_THREAD, BUILD_LWP, BUILD_THREAD):
Change to rely on PIDGET etc.
* config/i386/nm-i386sol2.h (TARGET_HAS_WATCHPOINTS,
TARGET_CAN_USE_HARDWARE_WATCHPOINT, HAVE_CONTINUABLE_WATCHPOINT,
STOPPED_BY_WATCHPOINT, target_[insert/remove]_watchpoint):
define. Allow target to use procfs hardware watchpoints.
* config/sparc/nm-sun4sol2.h: ditto.
* config/i386/tm-i386sol2.h (PIDGET, TIDGET, MERGEPID): modify
definitions to use 16 bits for the pid, 15 bits for the tid, and
1 bit for the flag.
* config/sparc/tm-sun4sol2.h: ditto.
(SOFTWARE_SINGLE_STEP, SOFTWARE_SINGLE_STEP_P): undefine.
* testsuite/gdb.threads/pthreads.exp (all_threads_running): Allow
for more than 15 thread increments.
