lib:util: Fix tfork return value if sigprocmask fails

2019-05-16T19:08:29+00:00

Returning a non-zero value from a function with bool as return value is
the same as returning true. Change the return value to false if
sigprocmask or pthread_sigmask fails to indicate failure.

tests util/tfork: Tests for status and event fd

2017-09-16T17:53:22+00:00

Add tests to ensure that:
- The event_fd becomes readable once the worker process has terminated
- That the event_fd is not closed by the tfork code.
  - If this is done in tevent code and the event fde has not been
    freed, "Bad talloc magic value - " errors can result.
- That the status call does not block if the parent process launches
  more than one child process.
  - The status file descriptor for a child is passed to the
    subsequent children.  These processes hold the FD open, so that
    closing the fd does not make the read end go readable, and the
    process calling status blocks.
