This cleans the libcurl usage up a bit. It moves common code used
to interact with libcurl into a single new file curl.[ch].

Notes:
* It does not alter any features nor fixes any bugs.
* Thew REVIEW about strdup(self->url) in event_url.c as been processed.
  According to the manpage for curl_easy_setopt()/CURLOPT_URL
  there is no need for us to copy.
* URL Auth as well as URL triggers have sent ICECAST_VERSION_STRING
  as User-Agent:, this has be corrected to what is set in the config
  file.
* As curl.c is now a single point for setting parameters all the TLS
  parameters should be reviewed and set (based on config).

Please test!

 * Reworded many log messages for better understanding.
 * Adjusted some version targets as we won't have a 2.4.2 release.
 * Added some FIXME comments

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.

This fixes some compiler warnings. The code should be warning free
if gcc with -Wall is used but for the following:
{{{
admin.c: In function 'command_manageauth':
admin.c:790: warning: unused variable 'mountinfo'
}}}
This warning is due <role> migration. See #2123 for more details on
this warning. Please test with care. closes 2063

Added .gitignore and submodules

The default mount is a block in the config file that contains settings for
all mount points that do not have a block in configfile themself.
This is implemented by a <mount type="default">-block.
In this case the <mount>-block MUST NOT contain a <mount-name>-subblock.

issuing a TouchFreq header on rejection.

Don't add to stream directory until a minute has passed, it seems like a few sites
are triggering YP requests because they are connecting and then dropping (probably
due to timeout), so at least make sure the stream is running a little while.
