This code is unused, so just remove it.

before_p is debug-only.

Add option to find and define where Ogg library resides via configure
script

Add delta encoder for index packets
based on OggIndex implementation

Both in case of functions for extracting and writing integers from/to ogg packets
return the shifted string pointer by the size of the integer.

As they are just examples how to use the library

Two new getter functions for skeleton v3.2 or later:
 * oggskel_get_segment_len: get the length of the segment
 * oggskel_get_non_header_offset: get the offset of the first non-header page

darn left out from the previous commit! :S

Fix configure.ac and add encoding functionality
It only supports 3.0 skeleton, i.e. indexing is not supported yet.

oggskel_get_keypoint_offset basically gives back the offset for
the nearest keypoint that is before a given time in the ogg container.

In previous version of skeleton specification the fisbone
headers stored the serial numbers of tracks with a 4
bytes unsigned integer. But in libogg and every other ogg
related library the serial number is stored by 4 bytes
SIGNED integer.

The skeleton specs has been updated (thnx Silvia), this
commit just follows the update.

credits to doublec

was a silly move to do that .... reverting to the previous code.

and initialise the bone and index pointers to NULL!

thnx to doublec and oggkoggk

Currently only decoding is working. The library can decode all
known skeleton headers, including index headers.

Contains only decoding part
