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.

Original commit message from CVS:
Rearranged cothread_switch a bit to move all the code for error conditions
to the end, using goto's to get there.  This has the presumed advantage of
consolidating all the normally run code into one chunk, reducing jumps
(and the associated penalties in any modern processor) and limiting cache-
line usage.  It may be instructive to look at the generated assembly for
this revision and the previous, to see if gcc is smart enough to do this
for us anyway.

If you want to turn off some of the checks (they are all checks for NULL
pointers, if you're curious) for a speed gain, disable the #define of
COTHREAD_PARANOID at the top.

Original commit message from CVS:
Added code to force the gsttypes plugin to load before gstelements, by
simply having gstelements.c request the plugin.  Solves some dependency
problems.  This is the correct method of doing this for now, though I had
a thought:

Have a static list of hard dependencies that the plugin system is responsible
for satisfying before even trying to load the plugin.  Makes plugin design
easier.

Original commit message from CVS:
Closed 22145 - gstelement.c: support hotswapping of loopfunc

Added a flag GST_ELEMENT_NEW_LOOPFUNC that's set when a new loopfunc is set,
which needs to be obeyed by the loopfuncs themselves.  The assumption is
that only a loopfunc or an element that knows what it's doing will ever
change the loopfunc pointer, so they can be responsible for exitting
the loopfunc itself appropriately.

The loopfunc_wrapper function has been changed to call the loopfunc
pointer itself in a loop.  If the loopfunc changes, the current loop is
supposed to exit, which causes the loopfunc_wrapper to start up the new
loopfunc.

instead of a single NULL->PLAYING.

Added an element flag to indicate that it cannot deal with noncontigous
buffers. If such an element is found in the pipeline, seeking is disabled
for the complete stream (avidecoder cannot deal with seeking until we convert
it to a loop based element with pull_region to fetch the indeces etc...)

Added plugin documentation. I fear we need a gstdoc implementation
that loads plugins and does introspection on them. I think we should

provide. Does anyone have enough perl knowledge to add these features? I
allready changed the C code to output the pad definitions but my perl
knowledge is too limited, for now, to implement the rest of the needed
functionality...
