* gstinfo.h: debugging functions
Changes made to the DEBUG system. New header file gstdebug.h holds the stuff to keep it out of gst.h's hair. DEBUG ... 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.

* GstDebugLevel:
* @GST_LEVEL_NONE: No debugging level specified or desired. Used to deactivate
* debugging output.
* @GST_LEVEL_ERROR: Error messages are to be used only when an error occured
* that stops the application from keeping working correctly.
* An examples is gst_element_error, which outputs a message with this priority.
* It does not mean that the application is terminating as with g_errror.
* @GST_LEVEL_WARNING: Warning messages are to inform about abnormal behaviour
* that could lead to problems or weird behaviour later on. An example of this
* would be clocking issues ("your computer is pretty slow") or broken input
* data ("Can't synchronize to stream.")
* @GST_LEVEL_INFO: Informational messages should be used to keep the developer
* updated about what is happening.
* Examples where this should be used are when a typefind function has
* successfully determined the type of the stream or when an mp3 plugin detects
* the format to be used. ("This file has mono sound.")
* @GST_LEVEL_DEBUG: Debugging messages should be used when something common
* happens that is not the expected default behavior.
* An example would be notifications about state changes or receiving/sending of
* events.
* @GST_LEVEL_LOG: Log messages are messages that are very common but might be
* useful to know. As a rule of thumb a pipeline that is iterating as expected
* should never output anzthing else but LOG messages.
* Examples for this are referencing/dereferencing of objects or cothread switches.
* @GST_LEVEL_COUNT: The number of defined debugging levels.
*
* The level defines the importance of a debugging message. The more important a
* message is, the greater the probability that the debugging system outputs it.
