  -----------
  [libc] add internal string class

The scanf implementation needs a dynamically resizing string class. This
patch adds a minimal version of that class along with tests to check the
current functionality.

  Log Message:
  -----------
  [libc] add scanf float converter

This patch adds the %f/F/e/E/g/G/a/A conversions for scanf, as well as
accompanying tests. This implementation matches the definition set forth
in the standard, which may conflict with some other implementations.
