Original commit message from CVS:
* gst/gstinfo.h: (GST_DEBUG_CATEGORY_EXTERN):
Remove __declspec(dllimport) for MSVC that was copied over into core
from a plugin, obviously without ever having been tested (note the
single underscore in _declspec in the initial commit), and that doesn't
really make sense.  See #492077.

* 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.
