sys/sys : proc.h signalvar.h sysctl.h
Log message:
Use the process ps_mtx to protect the process sigacts structure.
With this cursig(), postsig() and trapsignal() become safe to be called
without KERNEL_LOCK. As a side-effect sleep with PCATCH no longer needs
the KERNEL_LOCK either. Since sending a signal can happen from interrupt
context raise the ps_mtx IPL to high.
