Propagate missing playlist context fields (playlist_count, playlist_autonumber, n_entries, __last_playlist_index)

Browse Source 
The playlist/channel processing loop now sets playlist_count,
playlist_autonumber, n_entries, and __last_playlist_index on each
video entry so that templates like %(playlist_autonumber)s,
%(playlist_count)s, and %(playlist_index&{} - |)s resolve correctly
instead of showing NA.

Also updates _compact_persisted_entry to preserve n_entries and
__last_playlist_index across restarts.

Fixes #692
