f9b48c0cad Fix else working incorrectly from macros
Since the "skip ELSE blocks" variable is global, it used to get carried
over from the macro's `if` to the outer's.

ae77893021 Fix file name reporting
As noted in the function's code, this is very error-prone, but
will do the job; this needs rewriting due to #491 anyways, so, temporary.

9081feab51 Reinstate macro arg scan distance
Used to be broken, so it was removed, but doing so prevents escaping them.
So it was instead put back in, but with corrected behavior

81a77a9b88 Re-implement block copy to avoid expanding macro args
They were expanded during the capture, and there was no easy way to
avoid expanding them (believe me, after three hours and somehow an OOM, I
gave up trying).

149db9a022 Fix incorrect freeing of expansions

fed252bc49 Fix nested expansions being incorrectly handled
The biggest problem was simply that the length of children expansions was
not accounted for when skipping over the parent... this took a lot of
arduous debugging, but it finally works!

61b2fd9816 Add string expansion reporting
And fix line counting with expansion-made newlines.
This has the same bug as the old lexer (equs-newline's output does not
print the second warning as being part of the expansion).
Additionally, we regress equs-recursion, as we are no longer able to
catch this specific EQUS recursion. Simply enough, the new expansion
begins **after** the old one ends! I have found no way to handle that.

6dc4ce6599 Implement infrastructure around new lexer
The lexer itself is very much incomplete, but this is intended to be a
