* build/config_vars.sh.in: Trim more stuff from installed config_vars.mk.

Widen strip pattern to also match MOD_XML2ENC_LDADD.

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.

* build/config_vars.sh.in: Fix error if APU_CONFIG is not defined.

Enable to configure the https port - missing pieces.

update license header text

* build/config_vars.sh.in: Check for the *-config scripts both at the DESTDIR-relocated path and at the not-relocated path, to cope with both builds with and without the bundled APR.

* build/config_vars.sh.in: Prepend DESTDIR to paths to installed apr/apu-config scripts. Submitted by: Torsten Foertsch <torsten.foertsch gmx.net>

* build/config_vars.sh.in: Expand LTFLAGS here, to fix `apxs -q LIBTOOL` again. PR: 32787 Submitted by: William Barker <william.barker wilshire.com>

* configure.in: Define MKINSTALLDIRS and INSTALL in config_vars.mk. Don't use AC_PROG_INSTALL since any system "install" command is never used anyway. * build/rules.mk.in: Remove fixed reference to install.sh and mkdir.sh in abs_srcdir. * build/config_vars.sh: Munge definitions of MKINSTALLDIRS and INSTALL to use installed scripts.

Sanitize the installed config_vars.mk to remove references to the build and source directories, and to remove variables which are internal to the httpd build system: * build/config_vars.sh.in: New file. * Makefile.in (build/config_vars.out): New target. (install-build): Install build/config_vars.out as config_vars.mk. * configure.in: Add include path for srclib/pcre to INCLUDES rather than CPPFLAGS, and use a topdir-relative not absolute path name. Generate build/config_vars.sh. Reviewed by: Paul Querna PR: 20874, 28145
