[PATCH 1/6] psql: Abstract table formatting characters used for different line types.

printTextLineFormat describes the characters used to draw vertical
lines across a horizontal rule at the left side, middle and right hand
side. These are included in the formatting for an entire table
(printTextFormat). The printTextRule enum is used as an offset into
the printTextFormat line rules (lrule), allowing specification of line
styles for the top, middle and bottom horizontal lines in a table.
The other printTextFormat members, hrule and vrule define the
formatting needed to draw horizontal and vertical rules.
