The old implementation is no longer possibly due to limitations
of the new command line parser.

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This makes the code simpler and avoids mixing designated and
non-designated initializers in a potentially unsafe way in avconv.

It results in spurious errors when using the new preparser.

It splits the commandline into a more convenient internal representation
for further parsing.

This will allow e.g.
- processing global options first independently of their location on the
  commandline, eliminating ugly hacks for processing e.g. cpuflags
  first
- better options validation and error reporting. It is now possible for
  the parser to know that it's applying an input option to an output
  file or vice versa and act accordingly.

Separate the code that searches for the option to use and the code that
actually writes it. The writing code will be reused by the new options
parser.

This is required because there are some "holes" in the list for
compatibility with the fork.

The commit also removes the now unecessary check from cmdutils.

There is no point in duplicating this code in every get_buffer()
implementation.

This simplifies the condition to avoid hardcoding the systems
where the function exists. This also simplifies support for
newer Windows API subsets where this function doesn't exist,
such as Windows Phone 8 and the "metro" API subset of Windows 8.

This is an API break, but the function was introduced less than
two weeks ago.

This reverts commit 841bf0ef24.
This does not fully work as the file is used before the filename is parsed
so not all information is written in the specified file.

Filters now use null pointers to indicate having no input/output pads,

Fixes bug 352.

func2_arg is the same as func_arg, except it has one additional
parameter. Change all func_arg callbacks to take that parameter (and
ignore it).

Extract of the output:

Currently it takes a mask and value, such that options for which

Change it to take required flags and forbidden flags instead. This is
shorter and simpler to understand.

Don't require every caller to supply them.
