...
We still need to count parentheses in prepare_re for the current index
into "units", but the rest can ue re_nsub.

b2/: add "ignore" keyword for substitution rules
...
This allows us to decide in the project-specific rules how to indicate
DNP/NC/DNS/... parts. In the original BOOM, F1 == NC was hard-coded.

Not that we'd need giga-anything anytime soon, but since all the rest
also recognizes G, we support it here for consistency.

b2/: move all error handling from subex to subst
...
This makes checking of variables more strict: a variable can only
be used in the right -hand side of an assignment if it has been
assigned by an unconditional predecessor or if it has been matched
by a parent.
Things that wouldn't work anymore:
REF=X* {
FN=*V { X=Y }
Z=$X /* we can't be sure X=Y was taken */
}
FN=*R {
X=$REF /* no previous use of REF */
}

b2/: finish unit handling and move most of its processing to the match side
...
The ${foo#unit} syntax didn't really make sense because it created
a large number of potential error conditions on the assignment side
and didn't help with finding compatible fields.
With all this moved to the match side, an invalid syntax simply causes
a mismatch.
