util_script.c to ensure that that file is linked into httpd. Without this,
a httpd built with only http_core and mod_so modules would be missing
all the Apache API functions defined in util_script.

equivalent, similarly for x-compress and compress.  Apache
now ignores a leading x- when comparing encodings.  It also
preserves the encoding the client requests (for example if
it requests x-gzip, then Apache will respond with x-gzip
in the Content-Encoding header).

of people have pointed out, this is probably too major a change
this late in the game. My main intent was to clean up some of
the code where read()/write() is called in buff.c. Putting these
in libap seemed the logical place, but opens a whole can of worms
I did not forsee.

SharedModule, indicates that a module should be built as a shared library.
For example:

   SharedModule modules/standard/mod_status.so

(note the change of extension).

Building Apache will then build modules/standard/mod_status.so. This should
be copied into somewhere under the server root and loaded with a directive like:

   LoadModule status_module modules/mod_status.so

The compiler and linker flags for creating shareable and shared modules will
need adding for the supported OSes. I've put some default ones in for FreeBSD
and Linux. This can also be set in the Configuration file (if set here, it will
override the defaults contained within the Configure script). If there are no
SharedModule lines none of these extra options will be used anywhere in the
build process. If the final link of httpd requires any extra libraries
(typically -ldl) this will have to be given on EXTRA_LIBS in Configuration.

The Configure variables and Configuration options are

  CFLAGS_SHLIB     Options when building .o files ready for sharing
                   (e.g. -fpic)
  LDFLAGS_SHLIB    Options when linking .o files to .so (e.g. -Bshareable,
                   -export, -assert pure-text)
  LDFLAGS_SHLIB_EXPORT
                   Options required when linking httpd so that it exports
                   its symbols for linking at runtime (e.g. -Bdynamic,
                   -rdynamic, -export-dynamic)

The options used in Configure could be placed in Configuration like this:

  CFLAGS_SHLIB=-fpic
  LDFLAGS_SHLIB=-Bshareable
  LDFLAGS_SHLIB_EXPORT=-rdynamic

We preserve all the original functionality at the expense of some extra
memory because we don't clean up subrequests.

Plus a bug is fixed -- if mod_include is not the only module using
run_sub_request() then it was possible that add_xxx_vars() wouldn't be
done, and the environment would be incorrect.
