This commit cleanups codestyle a bit, yet there is still some work to be done

This sends the <admin> field to yp servers. It is thought be useful
to allow reaching the admins more easily in case of any yp problem.

Closes: #2146

This (hopefully) fixes a memory leak that caused active and
pending ypdata_t objects to be not freed up on server shutdown
or config reload.

To testers: please enable yp submission and restart and SIGHUP
your instance several times with loglevel set to warning or higher.
Each time after shutdown or SIGHUP check your log for one of the
following two warnings:
 * 'active ypdata not freed up'
 * 'pending ypdata not freed up'

Those warnings must not be in the log. If you spot one please report.

Corrected link pointing to http://www.icecast.org/svn.php to
point to http://www.icecast.org/download/ as this is what the
webserver now redirects to.

This adds info to the blocks about their size.
Also added two more blocks:
* for experimental features such as in private branches or
  or feature branches. This is for command IDs that are going to
  be merged with master some day. At merge they need to be changed
  and put into the regular position.
* for private features that are not going to be merged into master.
  e.g. specific features for a very specific user that are not
  useful for general audiance.

This should help keeping stuff sorted and largey reducing the risk
of command ID collissions on merges of branches.
Also this should make the merger's job a little bit more easy as
there are less likely any conflicts on merge if someone else got
a number closeby and those change is within the diff's context lines.

This re-adds a link to the config reload to the stats.xsl, the
admin interface.

This avoids a endless loop in a spin lock that has not been inited
yet if fserve engine was not started up by the time it was sent to
go down. This happened if icecast couldn't read the config because
the file was corrupted or non-existent.
Closes: #2144

This sets the on_demand parameter of the source correctly on
creation of a on-demand relay.

Closes: #2054

All Auth backends had just one prototype in auth_*.h. Those
got merged into auth.h to avoid to have many small files around.

No change to the license, just an updated copy.
This will make RPMLINT and debian complain less.

Correcting that the unordered list for authentication was wrapped in a table,
which is invalid.

git log 1a3fd18c..38dbb3a6

For the future we might want to consider if we still want to maintain
this and in which format.

This adds a little bit nicer display of <metadata> to the stats.xsl
page and avoids broken display of <metadata> and <authentication>.

This adds support to list global and per mount roles on stats.xsl.
This isn't nicest formated but works.
This also adds <source>-like <authentication> with <role>s to
root node.
Closes: #2133
