Rename _thr_enter_cancellation_point to _thr_cancel_enter, rename

2003-12-09T02:20:56Z

_thr_leave_cancellation_point to _thr_cancel_leave, add a parameter to _thr_cancel_leave to indicate whether cancellation point should be checked, this gives us an option to not check cancallation point if a syscall successfully returns to avoid any leaks, current I have creat(), open() and fcntl(F_DUPFD) to not check cancellation point after they sucessfully returned. Replace some members in structure kse with bit flags to same some memory. Conditionally compile THR_ASSERT to nothing if _PTHREAD_INVARIANTS is not defined. Inline some small functions in thr_cancel.c. Use __predict_false in thr_kern.c for some executed only once code. Reviewd by: deischen

environment. This includes support for multiple KSEs and KSEGs. The ability to create more than 1 KSE via pthread_setconcurrency() is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads. Those should come shortly. There are still some known issues which davidxu and I are working on, but it'll make it easier for us by committing what we have. This library now passes all of the ACE tests that libc_r passes with the exception of one. It also seems to work OK with KDE including konqueror, kwrite, etc. I haven't been able to get mozilla to run due to lack of java plugin, so I'd be interested to see how it works with that.
