Add an Override Class Index

This page pulls in directives that declare an <override> element and
groups them by class. The documentation for each class comes from
overrides.xml. Any undocumented classes are flagged with a boilerplate
fallback text (this situation is only likely to occur with a misspelling
or otherwise invalid <override> somewhere else in the documentation).

buildconf: allow configuration without APR sources

Previously we required copying the APR (and APR-util) source code into
srclib or some other location on disk in order to build httpd directly
from source. This is annoying if you're on a distribution that already
has the required files in its APR dev packages.

Practically speaking, if you're not building an official distribution
tarball, you only need the following files:

1) config.guess
2) config.sub
3) find_apr.m4
4) find_apu.m4
5) PrintPath

1 and 2 come from automake. 3 and 4 are included in some distributions'
(e.g. Debian's) development packages for APR/-util. That leaves
PrintPath, which has not changed meaningfully in over a decade and is
checked in completely here.

Passing an apr-config executable to buildconf's --with-apr option will
now enable a mode in which the above files (minus PrintPath) are copied
from their respective homes, removing the need for APR sources on disk.
Otherwise, if a sour...

core: Disallow Methods' registration at run time (.htaccess), they may be
used only if registered at init time (httpd.conf).

Calling ap_method_register() in children processes is not the right scope
since it won't be shared for all requests.

LibreSSL defines OPENSSL_VERSION_NUMBER = 2.0, but is not compatible with
all of the latest OpenSSL 1.1 API.

Address this by defining MODSSL_USE_OPENSSL_PRE_1_1_API which is true for
anything but OpenSSL >= 1.1 (for now).
