* src/imfs/linearfile.c, src/imfs/imfs_load_tar.c: New files.
* src/imfs/Makefile.am, src/imfs/imfs.h,
src/imfs/imfs_creat.c, src/imfs/imfs_debug.c,
src/imfs/imfs_eval.c, src/imfs/imfs_handlers_memfile.c,
src/imfs/imfs_init.c, src/imfs/imfs_initsupp.c,
src/imfs/imfs_stat.c, src/imfs/miniimfs_init.c: Added "tarfs".
This is not really a tar filesystem. It is a way to load a tar
image into the IMFS but actually leave bulky file contents in the
original tar image. It essentially adds the linear file type and
associated support and a loader routine.
