Remove xfa/src/fxfa/src/common and xfa/src/fxfa/src

This Cl moves the code in xfa/src/fxfa/src/common to the diretory which
contains the respective implementations and removes the xfa/src/fxfa/src/common
directory. It them moves all of the code in xfa/src/fxfa/src up one level and
removes the xfa/src/fxfa/src
directory.
