Fix trac ticket #1665.

With this option, transcoding DVB subtitles becomes possible.

The syntax of the 'glob_sequence' pattern type is explained in the image2
manual section, so there is no need to replicate it here.

Also discourage the use of such deprecated pattern type by not showing
examples employing it.

Replace the syntax explanation with an use example of the 'glob' pattern
type.

With this feature, it becomes possible to perform commonly
requested tasks, such as hardcoding bitmap subtitles.

This will be reverted once libavfilter has proper support
for subtitles. All the changes have the string "sub2video"
in them, it makes it easy to spot the parts.

Allows to disable interaction from standard input.
Useful, for example, if ffmpeg is in the background process group.
Roughly the same result can be achieved with "ffmpeg ... < /dev/null"
but it requires a shell.

It allows to send program-friendly (easy to parse)
progress information to a file or an URL.

Omitting the seconds has not worked for a long time, if ever.
Omitting the minutes too is just nonsensical for a duration
(it is indistinguishable from just seconds).

* adapt examples to new syntax
* mention that glob chars need to be enabled by a preceding % char
* note that globbing will be performed if both a printf and globbing
  pattern would be possible judging from the input pattern

Address trac ticket #1120.

Mostly useful for debugging purposes.

This allows to work around any non-monotonic time-stamp errors
by just discarding all time stamps.
This will be necessary to allow H.264 conformance tests to pass
after fixing time stamps to be passed through rawenc.
