Many files:
  unix.c (main): If compression is enabled on the filesystem, print a
  	warning message (for now).
  message.c: Add new compression shortcut: @c == compress
  problem.c, problem.h (PR_1_COMPR_SET): Add new error code.
  pass1.c (check_blocks): If the inode has EXT2_COMPRBLK_FL flag set,
  	check to see if the filesystem supports compression.  If it does pass
  	this information down to process_block() so it can treat the
  	compressed block flag words correctly.  If not, offer to clear the
  	flag, since it shouldn't be set.
  	(process_block): If an inode has the compressed inode flag set, allow
  	EXT2FS_COMPRESSED_BLKADDR.
  pass1b.c (process_pass1b_block, delete_file_block, clone_file_block):
  pass2.c (deallocate_inode_block): Use HOLE_BLKADDR to check to see if
  	the block can be skipped.
ChangeLog, Makefile.in:
  Makefile.in: Exclude the internationalization files from being
  	distributed.
ChangeLog, configure, configure.in:
  configure.in: Add support for --enable-compression.  This is
  	experimental code only for now, which is why it's under --enable test.
  	Once it's stable, it will always be compiled in.
