MC: Better handling of tricky symbol and section names

Because of win32 mangling, we produce symbol and section names with
funny characters in them, most notably @ characters.

MC would choke on trying to parse its own assembly output. This patch addresses
that by:

- Making @ trigger quoting of symbol names
- Also quote section names in the same way
- Just parse section names like other identifiers (to allow for quotes)
- Don't assume @ signifies a symbol variant if it is in a string.
