t/lib-httpd: dynamically detect httpd and modules path
In order to set up the Apache httpd server, we need to locate both the
httpd binary and its default module path. This is done with a hardcoded
list of locations that we scan. While this works okayish with distros
that more-or-less follow the Filesystem Hierarchy Standard, it falls
apart on others like NixOS that don't.
While it is possible to specify these paths via `LIB_HTTPD_PATH` and
`LIB_HTTPD_MODULE_PATH`, it is not a nice experience for the developer
to figure out how to set those up. And in fact we can do better by
dynamically detecting both httpd and its module path at runtime:
- The httpd binary can be located via PATH.
- The module directory can (in many cases) be derived via the
`HTTPD_ROOT` compile-time variable.
Amend the code to do so.
Note that the new runtime-detected paths will only be used as a fallback
in case none of the hardcoded paths are usable. For the PATH lookup this
is because httpd is typically installed into "/usr/sbin", which is often
not included in the user's PATH variable. And the module path detection
relies on a configured httpd installation and may thus not work in all
cases, either.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
