I'm not sure if this fixes any current actual problems as using slightly
stale data is normally only a problem when lines are being deleted, but
it's easier to fix it across the board than to figure out where it is
and isn't needed, and the speed impact of batching is trivial.

If called during a macro processing or validation function when the
subtitles have a valid file name (i.e. they've been saved and are not
Untitled), this returns the name of the file, without the path. If
called at any other time, it returns nil.

Lua's built in regular expression engine is rather limited in features
compared to wx's, and operates on bytes rather than characters due to
not being unicode-aware.

The macro processing function can now return a second value, which is
the index of the line to make active, which must be one of the lines in
the selection. If it is not, or if the value is not present, then the
active line is left unchanged if it is in the new selection, or set to
the first line of the new selection if it is not.
Closes#1435.

If the second return value from the validate function exists and is a
non-empty string, replace the macro's help text with that string.
Revert r6327, as this is a better solution to the same problem.
Closes#1413.

Rather than passing a string as the second argument to
aegisub.register_macro, they can now pass a function which will be
called (with no arguments) to get a help string.

Add agi::ProgressSink and agi::BackgroundRunner interfaces to libaegisub
which represent a generic progress sink and a thing which calls funtions
that need progress sinks. Make DialogProgress implement
agi::BackgroundRunner, invoking the passed function on a worker thread
and giving it a progress sink to update the dialog with.
Rewrite Automation4::ProgressSink, LuaThreadedCall and all related
classes to be based on agi::ProgressSink. Automation now simply uses
DialogProgress (although that's merely an implementation detail) and
adds a single method to route dialog opening from the worker thread to
the GUI thread.

Kill vfr.h and vfr.cpp and use the libaegisub versions of them instead.
Rather than the globals VFR_Input and VFR_Output, everything related to
frame rate is now part of the video context. Most things which used to
use VFR_Output now call VideoContext::TimeAtFrame etc.; video providers,
rather than modifying VFR_Input directly, now have getters for their
frame rates which VideoContext calls. Read-only public access to
VFR_Input and VFR_Output are still provided (hopefully temporarily) for
a few things which were awkward to do through VideoContext.
The Avisynth provider now might correctly handle VFR MKVs which can be
opened with DirectShowSource but not DSS2.
Rework keyframe handling as well, so that it continues to match the vfr
handling in design and implementation.
