Jan Schmidt 8244a3d688 resindvd: Add faststart, and work around some multi-angle issues 
Add a 'fast-start' property to the rsndvdsrc element, that attempts to
jump directly to the DVD menu when starting. Doesn't work correctly on all
titles yet.

Add workarounds for issues with multiple angles in libdvdnav: Use a heuristic
to avoid detecting discontinuities during multiple-angle titles, it seems
caused by libdvdnav losing some NAV packets in multiangle titles. Fix
seeking in multi-angle titles by aligning our sector calculation logic
with libdvdnav's. Also, use libdvdnav's dvdnav_get_current_time() method
to determine the logical position of the current cell when it changes, as the
cell_start value in the cell_change event provides a number that doesn't
compensate for angle cell blocks.
