404 is the expected result

This adds support to read metadata from Ogg/Opus streams:
 * Original sample rate from OpusHead,
 * number of channels from OpusHead,
 * Tags from OpusTags.

This adds spaces into the strings such as "nomatch" (-> "no match")
as returned by auth_result2str(). This is to improve readability of
resulting logfiles by most uses.

This fixes the number of arguments for ICECAST_LOG_INFO().
Why doesn't GCC warn about this?

This fixes a number of segfault happening in case config tags are
empty. This patch also adds warnings for most cases.

Please test for any regressions.
This should likely be ported to 2.4.4 as well.

Closes: #2265

libspeex reports warnings in case of oddnesses with the data to stderr.
However Icecast2 uses those functions in it's codec probeing process.
This way libspeex will write messages to a posibily reused random handle.

This is clearly a bug by package maintainers of libspeex.
See the source code of this change as well as libspeex's source code
as reference.

As proposed in #2272, this renames the mount specific
mp3-metadata-interval to icy-metadata-interval to prevent
confusion about what it does (setting the icy metadata
interval) and to make clear it's not mp3 specific but ICY
specific.

This changes the file extension check in a way that it no longer
ignores trailing characters. This significantly reduces the risk
for false positives while matching. However this invalidates old
setups with files like foo.xsl3. However I have never files like
that in the wild.

This is based on the patch privided by ePirat in ticket #2248.
