MFC r312452-r312512:

r312452-r312512:

- Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

This simplifies pathing in make/displayed output

- Use .CURDIR:H instead of .CURDIR to simplify pathing in output, etc

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.

META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.

This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

META_MODE: Remove DEP_RELDIR from Makefile.depend files.

This has not been needed since r284171 in projects/bmake.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Convert libraries to use LIBADD
While here reduce a bit overlinking

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

Just disable recoding support in libsmb if built WITHOUT_ICONV.

Bump the version of all non-symbol-versioned shared libraries in
preparation for 8.0-RELEASE. Add the previous version of those
libraries to ObsoleteFiles.inc and bump __FreeBSD_Version.

Bump the shared library version number of all libraries that have not
been bumped since RELENG_5.

-O2 compile isn't quite ready for WARNS=2 yet.

libsmb is now WARNS 2 clean on 64-bit platforms.

Zap now-unused SHLIB_MINOR

Supply SMB_CFG_FILE in CFLAGS. The newly imported smbfs-1.4.2
allows us to supply our own value for this, overriding the
default /usr/local/etc/nsmb.conf, which is not appropriate for
base system configuration files.

Add bmake glue for src/contrib/smbfs and connect userland smbfs
support to the build.

The MFC reminder below is subject to <re@FreeBSD.org> approval
prior to 4.5-RELEASE.
