to expressions when parsing source files matches the expected format.

This makes the error handling more robust. We saw the assumption
about the format of the tags being violated on one build system, and
it obscured the view on the underlying problem.

Rewrite all our macros using 'define-macro'. Use the new control flow
mechanism 'finally', or 'dynamic-wind' where appropriate. Make sure
the macros are hygienic. Reduce code duplication.

data structure is inspired by MIT/GNU Scheme.
