Fix T87967: M2T video seeking is broken

Bug caused by integer overflow in ffmpeg_generic_seek_workaround().
Function max_ii() was used to limit int_64tvalue.

After fixing the issue there was another issue, where near-infinite loop
was caused by requested_pos being very large and stream being cut in a
way, that it was missing keyframe at beginning.
This was fixed by checking if we are reading beyond file content.

VSE: Use lines to draw waveform

Refactor and improve waveform drawing.

Drawing now can use line strips to draw waveforms instead of only
triangle strips. This makes us able to properly visualize thin waveforms
as they would not be visible before. We now also draw the RMS value of
the waveform.

The waveform drawing is now also properly aligned to the screen pixels
to avoid flickering when transforming the strip.

VSE: Fix audaspace not reading ffmpeg files with start offset correctly

The duration and start time for audio strips were not correctly read in
audaspace.

Some video files have a "lead in" section of audio that plays before the
video starts playing back. Before this patch, we would play this lead in
audio at the same time as the video started and thus the audio would not
be in sync anymore.

Now the lead in audio is cut off and the duration should be correctly
calculated with this in mind.

If the audio starts after the video, the audio strip is shifted to
account for this, but it will also lead to cut off audio which might not
be wanted. However we don't have a simple way to solve this at this
point.

VSE: Fix video strip duration calculation

The video duration was not read correctly from the video file.

It would use the global duration of the file which does in some cases
not line up with the actual duration of the video stream.
Now we take the video stream duration and start time into account when
calculating the strip duration.

Fix: instances are made real when they shouldn't be

The original assumption that the `modifyMesh` function is only
called when the modifier is applied was wrong. There are still a
couple of other places calling it through `BKE_modifier_modify_mesh`.

Now there is an extra check that makes sure instances are only
realized when the modifier is actually applied.

Fix T90737: VSE adding nested strips could have non-unique names

Caused by {rBbbb1936411a5}.

When adding strips via the new SEQ_add_XXX_strip functions, the
`Editing->seqbasep` pointer was passed around.
Following in `seq_add_generic_update` this `seqbasep` pointer was used
to ensure a unique name.
But `seqbasep` is the pointer to the current list of seq's being edited
(**which can be limited to the ones within a meta strip**).

We need unique names across all strips though (since these are used for
RNA paths, FCurves as reported), so now use the scene's `Editing-
>seqbase` (**which is the list of the top-most sequences**) instead.

Unfortunately this might have screwed files to a borked state, not sure
if this could easily be fixed...

Fix T90364: buttons (partially) behind animchannel search block search

When channels are scrolled to be (partially) behind the search bar,
their widget buttons would still be interactive, preventing the seach
buttons to be usable.

We have to make sure the events are consumed from the search and dont
reach other UI blocks.
We can do so by flagging the block `UI_BLOCK_CLIP_EVENTS` -- but also
have to make sure the bounds are calculated correctly (otherwise the
check relating `UI_BLOCK_CLIP_EVENTS` in `ui_but_find_mouse_over_ex` wont
trigger properly.
