Simplify the usage of print_otag() by making it accept a variable

number of arguments.

Delete struct htmlpair and all the PAIR_*() macros.
Delete enum htmlattr, handle that in print_otag() instead.

Minus 190 lines of code; no functional change except better ordering
of attributes (class before style) in three cases.
