(or any directory in fact)

It might need a review and a clean up of the qt4 code.

 The input event vout now warns about every vout creation/destruction
due to a decoder.

Forward-port [a643d7e5]

Needed for input_SendEventVout()

It's reserved by gettext. gettext("") will output the headers.

Closes #2300

Untested
Closes #2306

Closes #2308

Closes #2307

Closes #2305

A new variable intf-event has been added.
It supercedes the following variables (they are still present for the
time being):
 - intf-change
 - intf-change-vout
 - rate-change
 - stats-change
and allows to have a better knowledge of the change done.

It is documented in vlc_input.h (in progress).

It allows to avoid the inclusion of input_internal.h

It fixes a bunch of missing locks and remove unused functions.
It splits input_internal.h

It will allows proper locking of p_item.

It will allows proper locking of p_item.

There is no functionnal changes except a few missing events added.

It is a common pratice to allows it for at least TS over RTP.
I have added an error message when using a odd port.

It was preventing mouse to work properly.
