update license header text
Revert r395231 from the 2.2.x branch. This gets us back to the old place with regard to the copyright statements.
Update the last year of copyright for the 2.2.x branch
Backport the Doxygen changes to the 2.2.x branch. No functional changes, however backporting these doxygen fixes makes it significantly easier to diff trunk and the 2.2.x branch, to sort out what's what. And we might as well release with nicer doxygen markup. Submitted by: Neale Ranns <neale ranns.org> Reviewed by: Ian Holsman

Remove many unnecessary includes, incl. apr_lock.h
Make the listener thread stop accepting new connections and exit cleanly at graceful restart time. This is a basic requirement of reliable graceful restarts (the kind that won't drop connections). This allows a future fix to make worker threads hang around until they service all connections previously accepted by the listener thread. The old mechanism of doing a dummy connection to wake up the listener thread in each old child process didn't work. It didn't guarantee that (in the main thread) the byte was read from the pod and global variables were set before the listener thread grabbed the connection. It didn't guarantee that a child process in the new generation didn't get some of the dummy connections. Rather than burn extra syscalls adding a unique socket or pipe to the poll set (and breaking single listen unserialized accept in the same change), this uses a signal sent from the main thread to the listener thread to break it out of the poll or accept. (We don't worry about breaking it out of the optional mutex because the child process holding the mutex will break out of poll/accept and release the mutex, allowing a child blocked in the mutex to get it. Eventually all children blocked in the mutex will come out.) Since the listener thread now exits reliably, the main thread joins it. PR: Obtained from: Submitted by: Reviewed by:
Update our copyright for this year.
Remove all signal handling from the worker MPM's child processes. Instead, we use the pipe of death for all communication between parent and child.
