Add an apache.mk, similar to java-vm.mk and emacs.mk, that allows apache

modules that will work with more than one version of the apache web server
to not require a separate package for each version of apache.  This was
originally based on java-vm.mk
	Makefile variables added:
		PKG_APACHE_ACCEPTED : Contains the list of valid versions of apache.
		USE_APR : If set, the package required apr to run.
	User variabled added:
		PKG_APACHE_DEFAULT : The version of apache to install, if there is
		                     none yet.  Defaults to apache13
	Variables set:
		PKG_APACHE : Which version of apache is being used.

+#
+# This Makefile fragment handles Apache dependencies and make variables,
+# and is meant to be included by packages that require Apache either at
+# build-time or at run-time.  apache.mk will:
+#
+#	* set PKG_APACHE to the name of the apache web serverused
+#
+#	* add a full dependency on the apache server
+#
+#	* optionally add a full dependency on apr
+#
+# The available user variables are:
+#
+# PKG_APACHE_DEFAULT is a user-settable variable whose value is the default
+#	apache server to use.  Possible values are apache13, apache2 and apache6.
+#   If there is already a version of apache installed this will have no
+#   effect.
+#
+# The available makefile variables are:
+#
+# PKG_APACHE_ACCEPTED is a package-settable list of servers that may be used as
+#	possible dependencies for the package.  Possible values are the same as
+#   for PKG_APACHE_DEFAULT.
+#
+# USE_APR is used to note that the package requires the Apache Portable
+#   runtime to build and execute.  This is only takes effect if apache2
+#   is chosen (by this file) as the web server to use.  This adds a full
+#   dependency on apr.
