The pre_mpm hook creates server-lifetime objects (or at least, for the
  generations across graceful restarts.)  They should use the process pool.

  When restarting [always graceful on Win32], we don't repeat pre_mpm
  (Unix doesn't, we shouldn't either.)  [Ryan Bloom]

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.

it is still trying to create worker threads

previously, after a non-graceful restart followed by a terminate
you could see a bunch of log messages showing the parent repeatedly
sending SIGTERM and finally SIGKILL to one or more children...
with this change, the sequence of messages should stop very soon

now that it has an RFC. At the same time, I revamped a good chunk of
the name <-> number mapping code in http_protocol.c

* add M_FOO constants for the new RFC 3253 (DeltaV) methods. label
  where each of the builtin methods comes from.

* moved METHOD_NUMBER_FIRST/LAST from http_protocol.h into
  http_protocol.c since they weren't used anywhere else and they
  weren't namespace-protected.

* create register_one_method() and use it to insert all builtin
  methods (at _init() time) and extended methods into the registry.

* add a lookup_builtin_method() to quickly map a method name to a
  builtin method number.

* rebuild ap_method_number_of() to use the new lookup function.

* revamp ap_method_name_of() to use the registry to locate the name
  for any method number. add a pool argument (no callers in the core
  code needed to be updated)

* revamp make_allow() to deal with the new method numbers and all
  extended methods.

* in mod_dav, use the new method numbers rather than registering the
  DeltaV methods.

in the situation where MaxClients is very high but
much fewer servers are actually started at the time of the
restart.

The way we notify an entire generation to die at once is
changed so that we don't have to use the pod (and deal with
the ease of filling the kernel pipe buffer).
