It is useless to read the stream data when flushing.

It should fix win32 build.

It is done by using __attribute__((__packed__)) when available.

 It has been replaced by generic timeshift at es_out level.
The only regressions I see is:
 - it is not (yet) possible to timeshift module that (wrongly) advertize
 pace control.
 - the new timeshift still uses too much memory (~20Mbytes per hour for DVB-T).

There are some problems:
- The data are stored in memory.
- Only pause/unpause are supported.
- Data are sent too fast to the next es_out.

It is not yet functionnal.

- x11-event option is renamed vout-event and become global
(libvlc-module.c)
- var_CreateGetInteger is called once at x11 initialization

The printf functions on Windows don't support the z length modifier,
which can shift field arguments, and causes an unconditional crash in
modules.c on start-up. For now, strip it on Windows and have vlc work
again, until a better solution is found and applied.

Default is not QAM_AUTO because ATSC is mainly using VSB_8 for non-cable operations.
Patch by Charles Hordis

Add a configure switch to allow disabling libsysfs support instead of letting it check what is on the build host and enable it accordingly. The default behavior is unchanged.
