MFC r314655:

bin: normalize paths using SRCTOP-relative paths or :H when possible

This simplifies make logic/output

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Merge the projects/release-pkg branch to head.

This allows packaging the base system with pkg(8), including
but not limited to providing the ability to provide upstream
binary update possibilities for non-tier-1 architectures.

This merge is a requirement of the 11.0-RELEASE, and as such,
thank you to everyone that has tested the project branch.

Documentation in build(7) etc. is still somewhat sparse, but
updates to those parts will follow.

Convert sbin/ to LIBADD
Reduce overlinking

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Migrate tools/regression/sbin/ to the new tests layout.

Pretty much all that this change does is shuffles the code around and hooks
it into the regular build. The code of the old tests has not changed.

Improve growfs(8) in a few ways; unfortunately, it's somewhat hard to untangle
them and commit separately.

1. Rewrite the way growfs(8) finds the device and mount point. This makes
it possible to use e.g. "growfs /mnt"; it's also used to display more
helpful messages.

2. Be more user-friendly, using descriptive messages, like this:

OK to grow filesystem on /dev/md0, mounted on /mnt, from 9.8GB to 20GB? [Yes/No]"

3. Allow to specify the size (-s option) just like with mdconfig(8), i.e. with
postfixes ("mdconfig -s 10g").

4. Reload read-only filesystem after growing.

Switch the default WARNS level for sbin/ to 6.

Submitted by: Ulrich Spörlein

Don't define FS_DEBUG by default, as this causes growfs to write debugging
information to /tmp/growfs.debug, which is a world-writable directory.

For variables that are only checked with defined(), don't provide
any fake value.

Catch up with recent gcc changes and introduce a DIP_SET macro
to use when setting values that depend on the UFS version.
Raise WARNS again.

Downgrade WARNS level until GCC 3.4.2 warning are fixed.

It seems growfs(8) is now WARNS?=6 safe.

Tested on: alpha, i386, ia64, sparc64

Temporarily go back to WARNS=0 until I can figure out what's breaking
the {powerpc, sparc64, ia64} tinderboxes.

Sorry for the noise. :-(

Make growfs WARNS=6 clean.

Remove these MAINTAINER lines since the maintainers has had their
commit bits retired for safe keeping.

style clean.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.
