[PATCH] git-tar-tree: make file contents accessible to write_header()

Browse Source 
Pass pointer to filecontents to write_header() and pass pointer
to filecontents, its size and some flags to write_exntended_header().
These parameters are not used, yet.  They are added in preparation
to symlink support.
