* Reorganized the kernel locking related to threads and teams. * We now discriminate correctly between process and thread signals. Signal handlers have been moved to teams. Fixes #5679. * Implemented real-time signal support, including signal queuing, SA_SIGINFO support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition of the real-time signal range. Closes #1935 and #2695. * Gave SIGBUS a separate signal number. Fixes #6704. * Implemented <time.h> clock and timer support, and fixed/completed alarm() and [set]itimer(). Closes #5682. * Implemented support for thread cancellation. Closes #5686. * Moved send_signal() from <signal.h> to <OS.h>. Fixes #7554. * Lots over smaller more or less related changes. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42116 a95241bf-73f2-0310-859d-f6bbb57e9c96
