add the ability to only output paths included in a spec file when creating
from a directory (-c)

Implement FreeBSD's -f spec1 -f spec2 spec comparision function. This
is more useful than -C and diff because it highlights the keys that have
changed value so for example, you can see that the size of a file has
not changed but the contents have. (brooks)

Don't depend on lubutil if we're building host tools. Fix tools build on
non-NetBSD hosts.

Complete the move of string_to_flags() and flags_to_string() from the
bin/ls sources to libutil:
o Bump libutil minor version number
o Fix uses to include <util.h> to pick up the function definitions
o Fix most uses of flags_to_string() to release the now-malloc()ed result

The "#ifdef UNUSED_BLOCK" in stat_flags.c wasn't so unused after
all -- it was used by the mtree source. So, instead do an "#ifdef
MTREE", and define that one when building mtree.

WARNS=3 seems to work for me

Now that <bsd.prog.mk> DTRT if HOSTPROG is defined (i.e, it is a no-op),
there's no need to special-case .include-ing it.

tweaks for fparseln(3) move from libutil to libc:
- remove #include <util.h> if nothing else needed it
- remove LDFLAGS+=-lutil if nothing else needed it

use NETBSDSRCDIR as appropriate

Add hooks to make mtree compilable from src/tools.

Add '-N dbdir', to specify that user & group lookups (via pwcache(3)) are to
be done from dbdir/master.passwd and dbdir/group, using simple text file
parsing routines.

with local crc.c, don't need usr.bin/cksum in .PATH any more

User interface changes from (or inspired by) FreeBSD:
- Add -L to walk the tree `logically', by following symbolic links in
the heirarchy.
- Add -P to walk the tree `physically'. This is the current behaviour,
and the default.
- Add "-X excludes-file" to give mtree the ability to exclude files and
directories from its traversal. excludes-file contains fnmatch(3)
patterns to exclude from the walk.
- Add "md5digest" synonym for "md5".
- Add "rmd160" keyword for RMD-160 message digest, and "rmd160digest" synonym.
- Add "sha1" keyword for SHA-1 message digest, and "sha1digest" synonym.
- Don't try to compare() other attributes if the type doesn't match;
it's nothing but trouble, and no use anyway.
- In -c, only emit "/set" records if something has changed since the
previous one.

User interface changes by me:
- Check a device's parameters before checking uid/gid/mode.
- If updating (-u), modify the following to match the specification:
- Device type (retaining existing ownership).
- Symlink target.

Fixes from (or inspired by) FreeBSD:
- Use p->ftslevel instead of own code to keep track of the level ourself.
The previous code got majorly confused if fts(3) couldn't descend
into a subdir, resulting in leaf nodes getting attached to the wrong
directory.
XXX: This new method is much much more robust, even though it's not 100%
perfect; it might result in a couple of following entries in the spec
to be incorrectly tagged as missing.
- Pass a useful pathname to rlink(), so that logical (-L) traversal
doesn't confuse symlink checking.
- Consistently use MAXPATHLEN+1 sized buffers for pathnames, so that
there's room for the NUL.
- Use mtree_err() and strerror(p->fts_errno) to report errors during
the fts(3) walk.

Fixes by me:
- Remove now-unused `const char *name' argument from compare().
- Change crc_total from an int to a u_int32_t, to match usr.bin/cksum/crc.c.
- Remove trailing whitespace.
- Remove unnecessary (void) casts on functions.
- Reorder entries in the getopt() switch.
- Replace strtoq() with strtoll(), and use strtoul() appropriately.
- Renumber F_ flags to be in alphabetical order.

complete WARNS=2 cleanup (with a bit of ickiness for the fts_open argv issue)

Make mtree a host tool and use it when appropriate.

Add "device" keyword, which allows the device number to be specified,
to be later checked and possibly created. Uses parsing and encoding
routines from mknod(8).

replace home-grown parser with fparseln()

code.c is no longer used, we use strsvis instead. Removed prototypes
from extern.h

Encode file names using strvis(3) when creating a specification.
Escape white space characters and `#' characters. Do the inverse
when reading specs.

This is a temporary fix until we have strzouvis(3) (or some such)
which is an improved version of strvis (taking an additional list
of characters to encode).

Fixes PR 5006 and PR 7663

add support for 4.4BSD file flags. we take a `flags=xxx' parameter,
using the same style of naming as chflags, ls & xinstall use, plus an
additional `none' to turn off a default setting.

use CPPFLAGS instead of CFLAGS

merge lite-2

Back out the .PATH.c changes. The .depend problem (and others)
will be fixed using the new .NOPATH make feature instead.

Use .PATH.c: ...

add NetBSD id's

clean up import, fix a few bugs, etc.

specify man pages the new way.

don't forget the man page. from Luke Mewburn <lm@rmit.edu.au>

fix oops

latest mtree from uunet. doesn't compile, but that'll be fixed soon.
(want to have 'pseudo-virgin' sources, for when fixed fnmatch stuff
is released...)

Add RCS identifiers.
