(apachectl graceful was broken.)

The best way to do this is to change configure to internally represent
the signal without the SIG prefix and prepend SIG before substitution
(and export a version without the SIG prefix for apachectl).

This highlights why we want to move apachectl's core functionality into
httpd.

  AFAICT, we have never created server configs of _all_ modules for _all_
  contexts, only when they come up (e.g., a directive of that particular
  module is provided) with the except that vhost containers complete the
  initialization of all modules.  I haven't stepped this, but it appears
  to be correct.

  This patch assures we can merge two incomplete directory sections
  together.  They will (obviously) need to be merged with a LHS default,
  e.g. a vhost's or main server's default dir config.  That's fine, this
  just allows either the LHS or RHS value to be null, and for merging to
  still succeed.

support it.  This defines a symbol called AP_SIG_GRACEFUL in
ap_config_auto.h which will have the appropriate signal value.  All
direct references to SIGWINCH have been replaced with AP_SIG_GRACEFUL.

On Linux 2.0, use SIGWINCH instead since SIGUSR1 is used by glibc
2.0's user-space threading library to control threads.  All later
versions of Linux/glibc don't have this problem.  (Not to mention the
security holes in older Linux versions which make it unsuitable for
use as a web server.)  If your platform doesn't have SIGUSR1, use the
appropriate mojo in configure to define what your graceful restart
signal should be.

In theory, a configure switch could be added to allow the admin to
specify the appropriate signal that should be used.  This is left
as an exercise to the reader for now.

The docs need to be updated.  Since the signal is now configurable,
just saying SIGUSR1 for graceful restart isn't completely true.  Also,
the apachectl functionality needs to be moved into httpd - this is
what Win32 does and it makes us consistent across platforms.

Roy issued a veto against use of SIGWINCH by default, so this should
resolve that veto.

providers. The old API was really based on how the FS stored properties, but
sucked for other types of providers (SQL databases, Subversion, etc). This
new code is overall much cleaner as it moves from a DBM style API to one
tuned for actual mod_dav operation; it also more flexible/clearer for future
improvements (e.g. dropping props directly to the wire rather than buffering
in memory).

This new API allows the provider to better define namespace handling during
the output of the values, how values are serialized and stored, the mapping
between elements' namespaces and the internalized namespace storage, a
clearer mechanism for naming properties (dav_prop_name), and an explicit
rollback mechanism to deal with PROPPATCH atomicity.

Updated the FS provider (fs/dbm.c) to the new API, mostly by moving code
from main/props.c. Of course, with the new semantics, some big changes in
the namespace mapping were made.

Expose some of the DAVFS' internal DBM cover functions and have the locking
