Subject: Fix the generation of the build-outputs.mk file. That file must
 remain platform independent since it gets included with the tarball, and the
 tarball is targeted for all platforms.

In this new scheme, the build-outputs.mk includes symbols named
OBJECTS_<plat> which specifies the necessary object files for each platform.
The apr_rules.mk(.in) file then pulls in the right symbol for the configured
platform. Since apr-util directly uses apr_rules.mk, then it picks up the
same logic with no change.

The build.conf was altered to include a set of platform-independent files,
and subdirectories which contain per-platform subdirectories. This was
needed to help out the logic which selects object files based on whether a
platform is present in each source subdir. (and if a platform subdir is not
present, then "parent" gets used instead; e.g. use 'unix' if 'beos' is not
in the subdir)

Lastly, configure.in was updated to select the appropriate set of objects
for the build.

* build.conf:
  (paths): remove per-platform symbols
  (platform_dirs): new option to list the dirs which have platform subdirs

* configure.in:
  - define and substitute OBJECTS_PLATFORM to reference the platform
    specific set of objects, which get defined in build-outputs.mk

* build/apr_rules.mk.in:
  - define OBJECTS in terms of the substituted OBJECTS_PLATFORM symbol

* build/gen-build.py:
  (PLATFORMS): the various platforms found in APR. unused, actually.
  (MAKE_PLATFORMS): the platforms which use a Makefile, and what default
    platform should be used if SUBDIR/<platform> is not present.
  (main): update logic to generate multiple OBJECTS_* symbols. this now
    includes logic to deal with subdirs which may not have a platform subdir
    for the platform in question, thus needing to default to another.
  (write_objects): some code factored out of main() to process a list of
    source files into dependencies lines in the makefile.
  (get_files): no more need to substitute for {platform}, and simplified
    some of the .split() stuff.
  (get_platform): no longer required. we generate for all platforms.
