Hmmm... why did git miss this?

* configure.in: Simplify/fix systemd detection: move later to fix autoconf warnings; define HAVE_SYSTEMD rather than using CPPFLAGS. * server/listen.c: Use HAVE_SYSTEMD for systemd #define. * modules/arch/unix/config5.m4: Update systemd headers check.

Add support for systemd socket activation to listener sockets.

Follow on to r1393976 and r1396424: mod_systemd: Specify "all" instead of "yes" (on Unix) so that APACHE_MODULE doesn't act as if the user requested it. General: Fix APACHE_MODULE so that failed prereqs will disable a module unless the user requested it explicitly. Result: By default systemd will be enabled where it actually works and disabled otherwise, but if the user requests it and the prereqs fail then configure will halt.

Follow up r1393976: Fix typo in enablement of mod_systemd that caused it to be enabled on non-Unix

* modules/arch/unix/mod_systemd.c: New module. Submitted by: Jan Kaluza <jkaluza redhat.com>

more configure-time support for dynamically loadable MPMs: . axe --with-mpm="shared" hack, replace with --enable-mpms-shared={all|list} . replace singular MPM_NAME with access to the list of enabled MPMs . replace singular MPM_SUBDIR with list MPM_SUBDIRS . enable OS/2 MPM in same manner as others with configure support instead of hard-coding in configure.in Current state: MPMs are built as static archives (but not linked to httpd) with --enable-mpms-shared, so they still have to be built with apxs to load dynamically.

Always make mod_*.h files available where they exist, modpath by modpath

Allow building httpd without a built-in MPM by specifying --with-mpm=shared on configure. When built thusly, an MPM should be loaded via LoadModule. (Currently you need to build the MPM with apxs.)

vi broke event ;)

Prevent empty test statement.

Add a header check for priv.h to mod_privileges.

* Don't build mod_privileges by default.

Introduce mod_privileges: a platform-specific module offering enhanced security and a (limited) solution to the "perchild" problem.

* We now need mod_unixd for worker, prefork and event as well.

Add mod_unixd to build, update svn:ignore.
