httpd bug fix and enhancement update

Updated httpd packages that fix several bugs and add various enhancements
are now available.

The Apache HTTP Server is a popular and freely-available Web server.

These updated httpd packages provide fixes for the following bugs:

* the removal of an upper limit on the configured LimitRequestFieldSize
setting.

* the removal of a restriction (the OPTIONS request) in the set of methods
which can be handled by a CGI script.

* the request method is escaped in the built-in HTTP error responses.

In addition, these updated packages provide the following enhancements:

* the addition of the "htcacheclean" cache storage management tool.

* support for filtering of responses based on the Content-Type in a reverse
proxy configuration

* directives such as the CacheSize directive, which are not implemented in
mod_disk_cache, now provoke warnings indicating that they are not available.

Users are advised to upgrade to these updated httpd packages, which resolve
these issues and add these enhancements.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
