There was an error how URIs were handled in our custom XSL loader
that rewrites include URIs to point to admin dir if the include
is not found in the current dir.

The check for the file would not work if the path contains chars
that are usually escaped in URIs, like a space (%20), as we get
a already encoded version of that URI in the loader and did not
decode it before checking the existence of the file.

(Fix #2249)

The autoreconf tool does the same tool detection the older
shell script does, and is now sufficiently widely deployed
to depend on. The new script is what is currently used in
other Xiph.Org projects.

Note this is a change to the new pattern of needing to
invoke ./configure separately after running ./autogen.sh.

(Fix #2254)

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 moved the <mime-types> setting into <paths>. The code still
supports reading it from the root element but will warn the user
about this.

Also there seems to be no documentation about this setting.

Closes: #2164

This adds support for allow-deny kind of rules with the matchfile API.

See: #2119

ban and allow file support has been moved into a generic implementation
that can be re-used by later code such as proxy matching or other
blacklisting.
See: #1959

When unset no default is used but the feature is disabled.
(The Shoutcast listen socket is not opened at all.)

Thanks to Jeremiah Rogers for pointing out.

This fixes a bug that could cause the global listener count of Icecast to
be negative. This was caused due to wrong handling of errors in the
format_prepare_headers function.

Fixes: #2199

Thanks a lot to Simeon Völkel (0xBD4E031CDB4043C9) for reporting
and investigating the bug.

This fixes some possible segfaults that could happen if the header
(re)allocation fails.

Also adjust formatting a bit, kill some trailing spaces.

Fixes: #2198

If there is a single "-" or it is only accompanied by whitespace, then
it wouldn't get escaped as it was detected as as a number. This would
produce invalid JSON.
This makes the numbers part ignore such and thus ensures it gets escaped
as text.

There might be other corner cases related to number parsing, this should be investigated.

https://github.com/doekman/xml2json-xslt/pull/20

 Some numeric values would not get formatted to valid JSON. This
 incorporates the suggestions from issue #15.

Also fixed whitespace of original patch.
Additional fix for related issue will follow.

This (hopefully) corrects the usage of realloc() as free().
This patch is part of the series based on Denis Denisov's input.

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.
