Avoid common symbols for fsck_lfs.

Add used-by comments on source files that are .PATH'd in from elsewhere.

global variables should be declared extern.

Support symlinks to a block device to resolve the name of the
corresponding raw device.

factor out rawname() from dump, fsck, savecore.

use getfsspecname()

share more code.

Centralize time printing and deal with ctime possibly returning NULL.

Make vmsg non-static, so it can be used directly by fsck_lfs.

use MAXPATHLEN instead of 32 as the size of the rawbuf

convert to use getprogname()

Cast pointer diffs to int for use in printf format width specifiers.
