This generates error pages based on IDs. This allows to reuse errors
and add more advanced information to them.

This patch also makes Icecast send in plain text OR HTML based
on the clients Accept:-string.

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

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.

See: #2248

This works around the problem that windows ignores tailing dots.
This way you could trick Icecast2 to send a XSLT file as plain text.

Please test.

Closes: #2247

This let util_url_escape() handle NULL passed as parameter.
In case the parameter is NULL it will also return NULL.

This patch also does some cleanup of the code such as migration
away from int and thus avoiding future failtures.

This is a re-apply of 3baa4e46
as git refuses to cherry-pick.

This is a first commit to correct minor problmes reported by
Denis Denisov. There is likely another commit to correct some more
such problems.

Thank you Denis Denisov.

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.

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 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

<event> has been added and can be used within <kartoffelsalat>
both in <icecast> and <mount>.
<event> takes backend depending <option> child tags.
Currently supported backends:
 - log: send message to error log.
 - exec: executes a program or script.
 - url: delivers the event via HTTP.

within <mount> <on-connect> and <on-disconnect> has been replaced by
<event>. Config parser can on-the-fly convert old tags.
Also <authentication type="url"> within <mount> has been fixed
for those cases with <option name="mount_add" .../> and
<option name="mount_remove" .../> which are now on-the-fly converted
by the parser to corresponding <event> tags.

Please also see TAGs added as per #2098. Some include hints for
documentation updates needed after this change. Those updates
should take place before 2.4.2.
