chs 33fa5ccbbf many changes for COMPAT_LINUX:
- update the linux syscall table for each platform.
 - support new-style (NPTL) linux pthreads on all platforms.
   clone() with CLONE_THREAD uses 1 process with many LWPs
   instead of separate processes.
 - move the contents of sys__lwp_setprivate() into a new
   lwp_setprivate() and use that everywhere.
 - update linux_release[] and linux32_release[] to "2.6.18".
 - adjust placement of emul fork/exec/exit hooks as needed
   and adjust other emul code to match.
 - convert all struct emul definitions to use named initializers.
 - change the pid allocator to allow multiple pids to refer to the same proc.
 - remove a few fields from struct proc that are no longer needed.
 - disable the non-functional "vdso" code in linux32/amd64,
   glibc works fine without it.
 - fix a race in the futex code where we could miss a wakeup after
   a requeue operation.
 - redo futex locking to be a little more efficient.
