Untested. Please test.
See #2063

This allows <resource> (former <alias>) to have only one of the
attribues source and destination. In that case other parameters
will be applied to the client but uri is not mapped.

See #2097

Add '?omode=legacy' to any URI or <resource ... omode="legacy" />.
Please test.
closes #2097

Old-style <authentication> within <mount> didn't work for type="url"
as well as some other parameters due to confusion between "node"
and "child" variable.

Thanks for trilliot for pointing out! Should work now.
closes #2039

Renamed event_config_read() into config_reread_config() and moved
it into cfgfile.c. This allowed to delete event.[ch].
event.[ch] will later be used to implement <event>.

Added .gitignore and submodules
Changed paths to match new location of things

This patch *replaces* the authentication system completly.

What is new:
 - <authentication> in mount section is now a container object.
 - <authentication> in root and mount section may hold any number of <role>-Tags.
 - <role> tags:
   Those tags define a 'role' and it's ACL rules.
   A role is a instance of an authentication module (see below).
   <role> takes the following options. All but type are optional.
   - authentication related:
     - type: Type of the authentication module (values: anonymous, static, legacy-password, url or htpasswd;
             symbolic constants in auth.h)
     - name: Name for the role. For later matching. (values: any string; default: (none))
     - method: This rule is only active on the given list of HTTP methods.
               (list of enum values: methods as recognized by httpp/ (e.g: get,post); default: *)
   - ACL related:
     - allow-method: Allowed HTTP methods.
       (list of enum values: methods as recognized by httpp/ (e.g: get,post); default: get)
     - deny-method: Rejected HTTP methods.
       (list of enum values: methods as recognized by httpp/ (e.g: get,post); default: *)
     - allow-admin: Allowed admin commands. (list of enum values: admin command; default: buildm3u)
     - deny-admin: Rejected admin commands. (list of enum values: admin command; default: *)
     - allow-web: Allowed web pages. (values: empty or *; default: *)
     - deny-web: Rejected web pages. (values: empty or *; default: (empty))
     - connections-per-user: maximum number of simultaneous connections per role and username.
       This is only active on active sources.  (values: unlimited or number of connections; default: unlimited)
     - connection-duration: maximum time of a connection. This is only active on active sources.
       (values: unlimited or number of secounds; default: unlimited)
   <role> takes <option> child tags. <option> tags contain a name and a value option.
   Meaning of <option> tags is up to the authentication module.
 - <role>s are considered to build a stack. If a role returns with AUTH_NOMATCH the next one will be tried.
 - <role>s are tested in this order: mount specific, default mount specific, global, internal fallback.
   Internal fallback is set to allow web/ access via GET, POST and HEAD (only GET supported by this time)
   and rejects all other requests.
 - New authentication module: anonymous
   This module matches all requests. No options taken.
 - New authentication module: static
   This module matches with a static username and password.
   It takes two <option>s. One with name="username" and one with name="password" to set username and password.
   This replaces old style <*-username> and <*-password> tags.
 - New authentication module: legacy-password
   This module matches with a statich password.
   It takes one <option> with name="password" to set password.
   This replaces old ICE and ICY (shoutcast compat mode) authentication.
 - Parsing <authentication> in <mount> with a type set in a special way to allow 100% backward compatibility.
 - Parsing of <source-password>, <admin-password>, <admin-user>, <relay-password> and <relay-user> in global
   <authentication> for 100% backward compatibility.
 - <alias> is now proccessed very early. This enables them to be used for all kinds of requests.

To Do List & What does not yet work:
 - type="url" auth: mount_add and mount_remove.
   This should be replaced by an unique feature I would call '<event>'.
 - Admin commands manageauth and manageauth.xsl are disabled as they need more review:
   This code needs to be ported to support multiple <role>s per <mount>.
 - url authentication module can not yet return AUTH_NOMATCH.
   This needs to be reviewed and discussed on how to handle this case best way.
 - Default config files needs to be updated to reflect the changes.
   As this is quite some political act it should be done in dicussion with the whole team
   and permission of the release manager.
 - Docs need to be updated to reflect the changes.

How does it work:
 Code has been changed so that authentification is done early for all clients.
 This allows accessing the ACL data (client->acl) from nearly everywhere in the code.

 After accept() and initial client setup the request is parsed. In the next step
 all <alias>es are resolved. After this the client is passed for authentication.
 After authentication it is passed to the corresponding subsystem depending on kind of request.

 All authentication instances have a thread running for doing the authentication.
 This thread works on a queue of clients.

Hints for testers:
 - Test with default config.
 - Test with diffrent authentication modules in <mount>.
 - Test shoutcast compatibility mode.
 - Test with new style <authentication> and any amount of <role> (zero to quite some).
 - Test <alias> lookup on all kinds of objects.
 - Test source level credential login into the admin interface.
 - Test shoucast style meta data updates.
 - Test playlist generation.

Thank you for reading this long commit message. Have fun reading the full patch!

In case of SOURCE we are lenient and thus quite some source clients
don't send a proper content-type, especially if they only support mp3.

This was meant to be introduced in 2.4.0 already, sadly we missed it.

All source clients MUST send proper content-type after migrating to 
Icecast HTTP PUT protocol.

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.

We are handling it the same as we would handle a SOURCE request.
Due to legacy code, sender MUST send proper content-type header,
if content type is not audio/mpeg!
Can be tested using real-time encoded output and piping it into
| curl -u username:password -H "Content-type: application/ogg" -T - http://localhost:8000/mountname.ogg
Note that this example has ZERO timing, so a simple 'cat *.ogg' will fail.
Whatever feeds the pipe must do it at proper timing for real-time playback!
