33e7269c37 typefindhelper: fix confusing debug log message
In case of a short buffer, the debug log is quite confusing.
Distinguish the two types of failure cases to make it clearer.

40187f9247 typefindhelper: Fix overflow some more
Nothing guaranteed that off+size wouldn't exceed a 2**64 value.

Instead we reverse the operation and use a subtraction.

5a72c23a54 Change some types to match their prototypes
Particularly note that the underlying integer type of the enum
GstTypeFindProbability is implementation dependent and may not match
guint.

991d6462a8 typefindhelper: Avoid using buffer_get_size in tight loops
Calling gst_buffer_get_size represented 2/3 of the cost of helper_find_peek
which was called whenever a typefindfunction wanted to peek at data.

We already know the size (from the GstMapInfo), so just use that.

461178fb59 typefind: fix prototype of helper_find_suggest
The proto for helper_find_suggest has a different argument than the actual
function in the same file has.  This causes the Sun Studio compiler to fail.

c4751ec8c1 Revert "context: use context on buffers instead of caps"
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.

8fff434835 typefind: add a new method that also uses the file extension
Add a method to perform get_range typefinding that also uses the
uri/location extension as an extra hint. It will first try to call the
typefind functions of the factories that handle the given extension. The result
is that in the common case, we only call one typefind function, which speeds up
the typefinding a lot.

5067664c09 typefind: Keep typefind factories sorted in the registry. Fixes #599147
This avoids having to do the sorting everytime we use typefind

The behaviour of gst_type_find_factory_get_list has subtlely changed
in the sense that the order was previously undefined, whereas now
it returns them sorted by rank and then by name.

Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (helper_find_peek):
Sort buffer cache list by end offsets. This makes sure that we don't
stop to search for a cached buffer that contains the requested data
too early.
Also read a minimum of 4k bytes instead of 512 bytes as this is a bit
more efficient. Fixes bug #459862.
