VPP-23 Re-work pager line collation

Browse Source

To better handle lines longer than the terminal width, re-work how
the pager collates lines. We still store each output line in a vector
or lines; additionally we index the start and end of displayable lines.

The index then becomes the data to work out what to display.

If the terminal is resized this index is rebuilt and the current page
redisplayed and an attempt made to keep the current top-of-screen line
in place.
