Original commit message from CVS:
More massive changes to the scheduling system.  Moved the scheduling code
to gstscheduler.[ch], so an child bin can replace the scheduler.
Introduced the concept of chains, which are subsets of the list of managed
elements for a given manager bin, which get scheduled as separate entities.
gst_bin_iterate_func should be pretty much fixed now, the scheduling code
gets to do all the hard work.

Cothreaded case work in the couple tests I've tried, chained is next.

Original commit message from CVS:
Cleanup in gsttypes.c:
removed the crazy GList of GHashTables, since the autoplugger will
use the GstCaps and elementfactories instead of the type system.
We don't maintain a list anymore of the elements for the specific
removed unused code in XML loading/saving.

Cleanup in gstelementfactory:
removed the register/unregister methods, register is now implicit when
gst_elementfactory_new is called. _unregister is now _destroy.
Removed logic to register/unregister the types in gsttypes.
added methods to query if the factory can src/sink a GstCaps
Make sure the elementfactory is set in the element_class when a new
element is registered with gst_elementfactory_new.

gst.c: properly register the basic bins
gst_pipeline: use new gstautoplug (next checkin)
gstprops: fixed an error in compatibility check
registry test program changes
plugins: misc changes for the new caps system.

Original commit message from CVS:
Header cleanup: try to include as little as possible; this will probably
speed up compilation a bit.
changed the .c files to use #include "..."
Fix for the 'plugins are loaded twice' bug.
Fix 22186: GstObject flags are now used everywhere. Added *_FLAG_LAST so
elements do not use the same flags. Added some padding in the flag enum
for future expansion.

Original commit message from CVS:
First attempt at rebuilding the type/plugin system
- make sure caps/props are saved in the registry
autoplugging is completely broken.
removed the typefactories and typeids from all the pads in the plugins
XML load/save is ok (be sure to rerun gstreamer-register)

Original commit message from CVS:
Changes made to the DEBUG system.  New header file gstdebug.h holds the
stuff to keep it out of gst.h's hair.  DEBUG prints out the process id,
cothread id, source filename and line number.  Two new macros DEBUG_ENTER
and DEBUG_LEAVE are used to show the entry and exit of a given function.
This eventually might be used to construct call trace graphs, even taking
cothreads into account.  This would be quite useful in visualizing the
scheduling mechanism.

Minor changes to various debug messages.

Also sitting in gstdebug.h is a prototypical DEBUG_ENTER that's capable of
performing DEBUG_LEAVE automatically.  It does this by utilizing a
little-known GCC extension that allows one to call a function with the
same parameters as the current function.  The macro uses this to basically
call itself.  A boolean is used to ensure that when it calls itself it
actually runs the body of the function.  In the meantime it prints stuff
out before and after the real function, as well as constructing a
debugging string.  This can be used eventually to provide call-wide data
on the DEBUG lines, instead of having to replicate data on each call to
DEBUG.  More research is needed into how this would most cleanly be fit
into some other chunk of code, like GStreamer (I think of this DEBUG trick
as a separate project, sorta).

Unfortunately, the aforementioned DEBUG trick interacts quite poorly with
cothreads.  Almost any time it's used in a function that has anything
remotely to do with a cothread context (as in, it runs in one), a segfault
results from the __builtin_apply call, which is the heart of the whole
thing.  If someone who really knows assembly could analyze the resulting
code to see what's really going on, we might find a way to fix either the
macro or the cothreads (I'm thinking that there's something we missed in
constructing the cothreads themselves) so this works in all cases.

In the meantime, please insert both DEBUG_ENTER and DEBUG_LEAVE in your
functions.  Be sure to put DEBUG_ENTER after your variable declarations
and before any functional code, not to put the function name in any DEBUG
strings (it's already there, trust me), and put a DEBUG_LEAVE if you care
enough.

Changes are going to happen in the way DEBUGs and other printouts occur,
so stay tuned.

more complex autoplugging. Update docs too.
Simplified the pipeline autoplugging code.
Changed the cothread case: One iteration is now a push from the src
element. The disk source does not change its state anymore on eof.
Better type setting for the ac3 parser/decoder and mpeg2parse.

Original commit message from CVS:
Fix on x86 architectures - was just checking for 386, D'oh.
Fix autogen to run autoheader _before_ autoconf, since it generates a
required file (config.h.in, which I just removed from CVS since its an
autogenerated one).  Also fix messed up variables in gst/Makefile.am

Original commit message from CVS:
Begun to add support for non i386 architectures, with the help of Chris
Emerson.  Added bits to configure to figure out architecture, and added
some alternatives for PPC.  Should cause no problems on i386, but I'll
check after this commit, but doesn't yet work on PPC by a fair way...

Original commit message from CVS:
Due to popular demand :-), I added a vorbis decoder.
The encoder is not yet functional.
Small cosmetic changes to gstcpu.c

Beware:
You *need* to install libvorbis.a from the main vorbis CVS.
you *have* to change the line in libtool to
deplibs_check_method="pass_all"
because else the plugin shared library refuses to link against the
static libvorbis.a library. This is a hack. I have no intention in
including libvorbis into the gstreamer CVS tree and making it
libtool compatible.
