[JGIT PATCH 1/2] Add raw buffer fetch methods to FileHeader, HunkHeader

["Shawn O. Pearce" <spearce@spearce.org>]

These permit application level code to read back the patch
script, for example to slice it up and output parts into a
UI on a per-file or per-hunk basis.

 Two last-minute patches.  While using this code in Gerrit 2 I
 realized I forgot to add a way to get the script back after its
 been parsed by the library.  :-)
