PATCH: Updated patch for strace to work with LinuxThreads programs

[Ganesan R. <rga...@my...>]

Patch attached. I've moved checking for standard signals (SIGSTOP, SIGCONT)
etc to the beginning of sigishandled() since this catches the common case
and is therefore more efficient.

Patch Summary:
/proc/pid/stat does not reflect the status of real-time signals, so strace
exits abruptly when tracing LinuxThreads programs. This patch makes strace
to read /proc/pid/status instead.
