everywhere.

We know that the core module has module_index 0. Therefore we can save
some pointer operations in ap_get_module_config(cv, &core_module) and
ap_set_module_config(cv, &core_module, val). As these are called rather often,
this may actually have some (small) measurable effect.

  and context document root (which is the file system directory that
  this URL prefix is mapped to). This generalization of the document
  root makes it easier for scripts to create self-referential URLs and
  to find their files.
- Expose CONTEXT_DOCUMENT_ROOT and CONTEXT_PREFIX as envvars, in mod_rewrite,
  and in ap_expr.
- Make mod_alias and mod_userdir set the context information.
- Allow to override the document root on a per-request basis. This allows
  mass vhosting modules to set DOCUMENT_ROOT correctly.
- Make mod_vhost_alias set the per-request document root

Remaining tasks:
- Use the context document root & prefix in mod_rewrite to make RewriteBase
  unneccessary in many cases. Do this without breaking compatibility.
- Write docs.

all of the complexities of building httpd against srclib/apr/ alone (along
with a seperate copy of srclib/expat/ owing to the removal of expat from
the apr tree).

We override exit() throughout the httpd build in order to intercept and
report our status through the service control manager.

We must include process.h prior to overriding exit().

I seem to remember that this is the reason apr.hw once included 
process.h unilaterally, to avoid this conflict over exit.

with APR 2.0.  This will allow httpd 2.3 to build against either apr-2.0
or apr+util 1.x.
