This is Darwin specific: the previous implementation was causing an integer
overflow when base.numer is very large. On PPC Darwin, the timebase info is 1000000000/33330116 and this is too large for integer arithmetic.

This file has been removed in newer MPD versions, so don't care about
it now.

Fixes gcc5 warning.

Return false on error, not nullptr.

Fixes -Winconsistent-missing-override (clang 3.6).

New in clang 3.6.

The definition of the playlist_plugin struct member of the embcue
plugin was incorrect.

Works around assertion failure due to something that appears to be a
(minor) FFmpeg bug.

Version 2.5 fixed an API oddity, however it broke API compatibility,
at least with C++.  Disable the workaround when a libavformat version
is detected that is recent enough.

The "::" to explicitly refer to the global namespace appeared like a
good idea in C++, but it breaks with C libraries that implement
standard functions using macros (e.g. musl).

Set the Error when zzip_seek()==-1 and not on success.  Fixes a crash
after seeking.

A negative uid value means it's not a "local socket" (PF_LOCAL).
uid==0 means user "root" connected.

Must return -1 on error, not 0.  0 is root.

Use the new uri_get_suffix() overload that removes the query string.
