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.

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.
