Adds two new apodization functions that seem to perform better than
the apodization functions currently in the codebase and fixes three
existing windows as well.
Its important to note that this patch only affects the encoder stage
that evaluates various possible predictors. Audio encoded with these
new windows will still decode with existing legacy decoders.
= Theory =
These functions are used to window the audio data at the predictor
stage. These news functions enable the use of only part of the signal
to generate a predictor. This helps because short transients can
introduce noise into the predictor. The predictor becomes very good
at prediciting one part of the signal, instead of mediocre for the
whole block.

The html documentation was diff'ed to the current website pages
and all difference were merged into the page they weren't yet
incorporated. This includes lots of small fixes and
improvements.

For some reason all documentation lists the max rice partition
order to be 16, while the maximum is 15. This fixes flac -H, the
man page and the HTML source code documentation

While developing FLAC Frontend, there where several occasions where
I felt little restrained because the FLAC logo is available only in
gif. I made an SVG version and rendered a new GIF version from it.

The changelog declared "charset=ISO-8859-1", but used a UTF-8 encoded
name. Change the declaration to UTF-8 to fix this.

This commit accepts the new default channel masks for 6.1 and 7.1
surround input WAV files, and writes the corresponding masks when
decoding to WAV without a channel mask from the metadata block.
The local copy of the format spec is also updated with the new text
from the flac-website repository.

When building outside of the source tree, the Doxyfile needs to be
generated in the build tree and should point to the proper paths for
include directories and html footer.
The generated api files to install should also be taken from the build
tree instead of the source tree.

The autoreconf tool is provided by autoconf to do what custom
autogen.sh scripts in many projects used to do. Only it is more
robust and widely tested. It has been available for several years,
too. No reason to rely on custom code for this.
