Jan Kiszka	99b5beba2f	coroutine: Fix setup of sigaltstack coroutines ... Use pthread_kill instead of process-wide kill to invoke the signal handler used for stack switching. This may fix spurious lock-ups with this backend, easily triggerable by extending the time window between kill and sigsuspend.

Alex Barcelo	3194c8ceeb	coroutine: adding sigaltstack method (.c source) ... This file is based in both coroutine-ucontext.c and pth_mctx.c (from the GNU Portable Threads library). The mechanism used to change stacks is the sigaltstack function (variant 2 of the pth library). v2: Some corrections. Moving global variables into thread storage (CoroutineThreadState).
