This reverts commit b9d08c77.

After taking MoveFileEx into use, we can replace files with renames
on windows as well.

This allows getting the normal unix semantics, where a rename
allows replacing an existing file.

Based on a suggestion by Reimar Döffinger.

This doesn't add any dependency on library internals, since this
only is a static inline function that gets built into each of the
calling functions - this is only to reduce the code duplication.

Moving line_num into FFServerConfig as parser state,
saves many passes of it aside of FFServerConfig pointer.

ffserver_save_avoption() and ffserver_opt_preset() have
redundant arguments. They can be obtained basing on media type.
This simplifies uses and reduce chance for a mistake.

  movenc: Add a flag for indicating a discontinuous fragment

This allows setting the right fragment number if doing
random-access writing of fragments, and also allows reading the
current sequence number.
Signed-off-by: NMartin Storsjö <martin@martin.st>

This allows creating a later mp4 fragment without sequentially
writing the earlier ones before (when called from a segmenter).

Normally when writing a fragmented mp4 file sequentially, the
first timestamps of a fragment are adjusted to match the
end of the previous fragment, to make sure the timestamp is the
same, even if it is calculated as the sum of previous fragment
durations. (And for the first packet in a file, the offset of
the first packet is written using an edit list.)

When writing an individual mp4 fragment discontinuously like this
(with potentially writing the earlier fragments separately later),
there's a risk of getting a gap in the timeline if the duration
field of the last packet in the previous fragment doesn't match up
with the start time of the next fragment.

Using this requires setting -avoid_negative_ts make_non_negative
(or -avoid_negative_ts 0).
