Make "install -l s[ar]" act like "ln -sfh" as intended. This fixes
installation of symbolic links where the target is a link is to an
existing directory.

Introduce six new options from NetBSD:
* -M <metalog> Log metadata in mtree format.
* -D <destdir> Log paths relative to <destdir>.
* -h <hash> Log digest of type <hash>.
* -T <tags> Specify which mtree tags to log.
* -l <linkflag> Create hard or symbolic links (allows logging).
* -U Install without root privileges (owner, group, mode,
and flags can be logged via -M

NOTE: In the interest of compatibility with NetBSD and because it is the
obvious letter, the nearly useless -M option (disable mmap) has been
repurposed.

Approved by: re (rwatson)

A little bit of anti-foot-shooting. Use utimes(2) rather than
the deprecated utime(3). utimes(2) uses timeval, but utime(3) uses
time_t's. If you do bad things (like I did) by mixing up include files
with libc, then install can do strange things if you mismatch the time_t
stuff. utime() is emulated entirely within libc.

Use the correct timestamp for the -C -p case when the comparison fails.
A garbage timestamp was used for at least installing /dev/null with -C -p
when the target doesn't already exist.

Switch over to using the new fflagstostr and strtofflags library calls.

Historically file flags (schg, uschg, etc) have been converted from
string to u_long and back using two functions, flags_to_string and
string_to_flags, which co-existed with 'ls'. As time has progressed
more and more other tools have used these private functions to
manipulate the file flags.

Recently I moved these functions from /usr/src/bin/ls to libutil,
but after some discussion with bde it's been decided that they
really ought to go in libc.

There are two already existing libc functions for manipulating file
modes: setmode and getmode. In keeping with these flags_to_string
has been renamed getflags and string_to_flags to setflags.

The manual page could probably be improved upon ;)

PR: Loosely related to bin/8252
Approved by: jkh and bde

Treat an EOPNOTSUPP from fchflags() as a non-fatal case. Only warn about
it if flags were explicitly specified on the command line. Do not warn
if we were merely trying to preserve flags or remove UF_NODUMP. NFS does
not support flags.

I'm not sure that this is ideal, but it should do for now. Installing
a plain file onto a NFS server must work, we used to silently ignore the
attempt. Doing a binary install looses the flags anyway since cpio
doens't preserve them with the cdrom/network images.
XXX make world should not use flags or chown/chgrp in the obj/tmp area.

This is based on a suggestion from Ken Merry <ken@plutotech.com>.

Converted to Lite2 mount interface - don't use numeric filesystem
types. The NetBSD compatibility cruft was more correct for -current
than FreeBSD's own code. It just used NetBSD #defines instead of
string literals for the filesystem names. NetBSD's MOUNT_UFS is
"ffs", so using a literal "ufs" gives wrong results, but this is
unimportant, especially for bootstrapping.

Fixed style bugs in trymmap().

Fixed some disordered declarations.

Change MAP_FAILED to type void *.
Typo fix.

Add an option (-M) to install to disable use of mmap(2). This is kinda
handy at the moment with -current's mmap+unlink interactions.. The
problems seem worst when using INSTALL="install -C" in /etc/make.conf.
This could well come in handy in the future too.

Allow install to build from FreeBSD source using NetBSD tools and
headers during the port of FreeBSD to a NetBSD supported architecture.
FreeBSD needs to be able to install itself from very early on.

1) Create intermediate directories with 755, not 777
2) Exit with error diagnostic if file exists but not a directory (-d)
3) Do chmod independently of chown (-d)

1) Ignore -C with -d, not fail (for $(INSTALL) macro from /etc/make.conf)
2) When uid/gid not specified, not try to set 0:0 owner, just do nothing.
It makes possible to use install -d by users without setting
their uid:gid each time.
3) Be more specific where install_dir fails

When calling strip, temporarily close the file, call strip and then
reopen it after strip has finished. This makes it work when
/usr/bin/strip replaces the file rather than doing an in-place edit
(such as the binutils-2.8 strip, which is a variation of objcopy).
This is necessary if install(1) and strip(1) are going to cooperate
on an ELF system.

Uncomment sccsid string and enclose it inside #if 0/#endif.
Cosmetic in man page.

Bootstrap aid from older releases.. 'make world' can't build xinstall
until the includes are installed, and it doesn't install the includes until
xinstall is built (the previous xinstall binary may not have -C). As a
bandaid, define MAP_FAILED ourselves if <sys/mman.h> didn't. Perhaps it
would be safer to simply disable mmap if all the prerequisites are not
there.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Sweep through the tree fixing mmap() usage:

- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.

Be more careful with mmap. If it fails, fall back to a plain compare or
copy.

Dont leave stray INS@xxxx temp files around, especially when installing
something less than 8MB and the destination runs out of space, etc.

It still doesn't clean up the temp files on SEGV or other signals etc.

accidently removed the "dont compare > 8MB files hack".
didn't rewind the files after the read()s in the non-mmap compare.

Only attempt to mmap() files from a ufs or cd9660 fs for comparing or
installing. mmap'ing stuff over a nfs mount took out my machine during
a 'make world' last night while I was asleep. I started out with a list
of fs's to avoid, when I realised that I really didn't know which ones
were safe with mmap, so I went for the ones I knew and implemented a
fallback compare.

Add a simple -v (verbose) option that allows you to see when -C actually
installs something. This is not 100% right, since it has a false hit
when install -C snaps hard links.

Also, run strip(1) from the $PATH, otherwise you need a special version
of install to install (say) elf binaries which have a different strip.
With JDP's elfkit, the layout of the path determines which binary format
you are generating.
