Add the first batch of mandoc(1) regression tests, testing for a few bugs

fixed in 1.9.9 and some older, rather subtle issues in list displays.

Directory layout and naming scheme was chosen such that later inclusion
of tests for -man and -Thtml will not force us to rename everything,
even though the layout might still seem a bit sparse right now.
More tests will slowly be added while investigating and fixing issues.
