  Log Message:
  -----------
  [libc] add scanf reader

This is the interface that will be used to read from a file or string in
scanf. This patch also adds the string and file implementations of the
reader, although the file reader is not yet complete since ungetc has
not yet been implemented.

  -----------
  [libc] add scanf string converters

This patch adds the basic conversion facilities to scanf as well as unit
tests for them. It also adds scanf_main which will be used for the
eventual scanf entrypoints.
