Improve error handling in the eqn(7) parser.
Get rid of the first fatal error, MANDOCERR_EQNSYNT.
In eqn(7), there is no need to be bug-compatible with groff, so there
is no need to abondon the whole equation in case of a syntax error.
In particular:
* Skip "back", "delim", "down", "fwd", "gfont", "gsize", "left",
"right", "size", and "up" without arguments.
* Skip "gsize" and "size" with a non-numeric argument.
* Skip closing delimiters that are not open.
* Skip "above" outside piles.
* For diacritic marks and binary operators without a left operand,
default to an empty box.
* Let piles and matrices take one argument rather than insisting
on a braced list. Let HTML output handle that, too.
* When rewinding, if the root box is guaranteed to match
the termination condition, no error handling is needed.
