Recursive parsing is not handled anymore by accesses.

All readdir access that are used from demux directory can now be sorted like
the directory access.

Sort all p_item children of the node recursively.

Since items are already sorted by the server.

It now takes two new bool* arguments.

 - specify if the access returns items that are already sorted.
 - specify if directories can loop into themselves

The main advantage is to move the management of the input_item_node_t from all
accesses to the directory demux.

Fallback to the remote Home directory.

The JNI module is now a submodule.

Add the mc_api struct, used by Decoder to access a MediaCodec API.

Rename OpenMediaCodec to StartMediaCodec and CloseMediaCodec to StopMediaCodec.

This ensures that SIGPIPE is not emitted if the connection is closed by
the other end. Using send() is fine given that all net_Write(),
net_vaPrintf() and net_Printf() call sites use (only) sockets.

If the decompression process exits unexpectedly (or otherwise closes
the read end of the pipe), we want EPIPE, not SIGPIPE.

The mutex needs to be unlocked while the thread sleeps. Otherwise, a
deadlock may occur in case of contention for the mutex.

Signaling an event ensures that at least one thread wakes up, but it
does not warrant that all of them do.

(No functional changes)

This avoids SIGPIPE firing when writing to a remote-closed connection-
oriented socket (it is useless for datagram sockets or on Windows
though). SIGPIPE is blocked ins VLC, but not necessarily in LibVLC.

The problem remains for write() on broken pipe and sockets.

Removes singleton, fixes initialization and deletion. Renames to
AddonsWindowController.
