Incorporate fixes from Dimitry Andric:
- Use a BUFFER_GROW() macro to avoid rounding errors in capacity
calculations.
- Fix a bug introduced in [r3531].
- Fix handling of nested template parameters.
Ticket: #581
This should fix a number of assertions on elftoolchain's cxxfilt, and
allow it to correctly demangle several names that it could not handle
before.
