the matching SID. This is our username used for privsep then.

Support profiling of multi-threaded apps. This patch set modifies Cygwin's profiling support to sample PC values of all an app's threads, not just the main thread. There is no change to how profiling is requested: just compile and link the app with "-pg" as usual. The profiling info is dumped into file gmon.out as always. A new facility enabled via the environment variable GMON_OUT_PREFIX. This facility is intended to match an undocumented Linux glibc feature. Exporting the variable with a non-empty value such as "foo" causes the profiling info to go to a file named foo.$pid instead of the default. With that, both resulting processes of a fork() can have their profiling data captured in separate files. gprof already knows how to accumulate data from multiple files if they all pertain to the same app. There is no change to the normal Cygwin execution paths if profiling is not enabled. And when it is enabled, only the one profiling thread per profiled app is doing more work than it used to. * include/sys/cygwin.h: Add CW_CYGHEAP_PROFTHR_ALL. * cygheap.cc (cygheap_profthr_all): New C-callable function that runs cygheap's threadlist handing each pthread's thread handle in turn to profthr_byhandle(). * external.cc (cygwin_internal): Add case CW_CYGHEAP_PROFTHR_ALL. * gmon.c (_mcleanup): Add support for multiple simultaneous gmon.out* files named via environment variable GMON_OUT_PREFIX. * gmon.h (struct gmonparam): Make state decl volatile. * mcount.c (_MCOUNT_DECL): Change stores into gmonparam.state to use Interlocked operations. Add #include "winsup.h", update commentary. * profil.c (profthr_byhandle): New function abstracting out the updating of profile counters based on a thread handle. (profthr_func): Update to call profthr_byhandle() to sample the main thread then call cygheap_profthr_all() indirectly through cygwin_internal(CW_CYGHEAP_PROFTHR_ALL) to sample all other threads. (profile_off): Zero targthr to indicate profiling was turned off. (profile_on): Fix handle leak on failure path. (profile_child): New callback func to restart profiling in child process after a fork if the parent was being profiled. (profile_ctl): Call pthread_atfork() to set profile_child callback.
