 * 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

Fix variable alignment if necessary.

This fixes another memory leak, which was caused by not freeing
the admin_path when a subsequent xslt file was loaded.

This fixes some memory leaks in the xslt loader,
additionally it now makes no copy of the URI if not needed.

This switches the behaviour introduced with the last commit
so that now the admin folder is only checked for includes if
in the specified path none is found.

This adds support for including xslt files that are in the admin
directory in an xslt file which is in the webroot, without having to
specify the full path.

For example:

    <xsl:include href="includes/head.xsl"/>

will look inside the admin directory (foo/bar/admin/includes/header.xsl)
and include it, if it's found. If not it will as usual look for it in
the directory where the xslt file is located. This enables us to have
common files like the header, footer, json stuff, etc. in the admin
directory, so we don't need to have an extra copy in the web folder.

Note:
The configuration value for the admin directory is requested
every time an xslt is requested (if not in the cache).
Additonally it should be noted that the includes are not cached.

Trying to make it really clear so that more users get it right.

We haven't been using VS6 to build Icecast for a while.
We won't be bringing back the management UI, as everything is now
accessible through either web-ui or start menu.

Proper Windows service handling remains on todo list for 2.5.0.

Copied by permission from the quake2world project.

This script helps package Icecast into a Windows installer.
It is used for the mingw32 builds of Icecast.

This adds the Transfer-Encoding chunked to PUT support.

Please test carefully. Will add PUT to Allow: header after testing.

Have fun.

Closes: #2088

This tries to unbreak the 100-continue thing a bit.
Proper headers are send in case of 100-continue. Also the 200 OK
was moved to the end of the stream.
The client may even be reused. But I'm not sure we only do
'End of stream' in cases we are not on an undefined state of the
client. Do we as of now support anything that give us EOS without
a fatal socket state (error or shutdown)?

At least this unbreaks 100-continue with active TLS that was broken
as hell as we sent the header in clear over the socket. Not checking
if it was transmitted completly or something. Using lowlevel socket
calls (in contrast to the connection level calls that would have
handled the TLS just fine).

While this seem sto be a huge improvement to the situation I kindly
ask you to do a lot testing on this. Both with SOURCE as well as
PUT clients.

We have answered SOURCE/PUT requests with a simple
"HTTP/1.0 200 OK\r\n\r\n" while we should answer with complet
headers. This commit corrects this.

Interoperability:
This will work for two classes of clients:
 * Super dumb ones not checking the response and will just send
   data and hope the socket is still open.
 * Those with a real parser.
 * Shoutcast clients (indepnded code path).
 * All libshout, curl, wget, ... based clients.

This *could* break:
 * Clients that check for the exact returned message. However
   as we start with the same string this should work.
   Only client that check for the string including the End-of-header
   CRLF sequense may break.

Please test careful before release.

This exposes the TLS status as <tls> tag in the <listener> tag.
The tag contains a bool ("true" or "false"). TLS mode, version and
other parameters are out of the scope of this tag and may be added
as independed tags in later commits.

This converts the <Listeners> tag to lowercase on listclients admin
command. This is to align with stats.xml which already uses lowercase.
See: #2097

This fixes a bug in 8941de32:
When passing NULL as client parameter to util_http_build_header()
there was a segfault before this change.

This announces TLS support if enabled via Upgrade:-header.
Closes: #2159

This allows the usage of RFC 2817 style upgrade commands.
This is not correctly announced yet.
Can hardly be tested as most clients do not support this.
Will be helpful with TLS support in libshout.
See: #2159, #2152

This adds the function create_client_node() taking care of
client queue node creation.

This adds to all responses:
 * "Accept-Encoding: identity"
 * "Connection: close"
 * "Allow: GET, SOURCE" or "Allow: GET" (on admin pages)

This is to generate some infrastructure for Icecast to tell futur
source clients what is supported.

"Upgrade: TLS/1.0" should be added later when upgrade support is present.

See: #2152

Added stamp-h1 to the gitignore file to prevent commiting it accidentally

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
