Siddhesh Poyarekar 439bf404b8 Allow a single-threaded program to cancel itself 
There is nothing in the POSIX specification to disallow a
single-threaded program from cancelling itself, so we forcibly enable
multiple_threads to allow the next available cancellation point in the
thread to run.

Also added additional tests to cover various cancellation scenarios.

Ulrich Drepper 86a4c67fb9 Implement interfaces to set and get names of threads. 
At least the Linux kernel provides field where the kernel originally
stores the command which is executed by the thread.  The value can
subsequently be overwritten.  The added functions allow to do that for
threads, providing and abstraction around the syscalls or /proc file
system accesses needed.

The syscall wrappers had to save and restore the syscall parameter
values and return value when calling the functions to enable/disable
cancellation were called.  Not anymore.  The called functions are
special and don't modify any unexpected registers.

Ulrich Drepper 515a8908ce Make x86-64 pthread_cond_timedwait more robust. 
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi

the calls.
