Update share/examples/* to properly install /usr/share/examples.

As result of this, a new examples package is now created.

Note, this is only effective with 'SHARED=copies' (the default),
as the 'SHARED=symlinks' mechanism will create a symlink to the
source tree version of the file(s).

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.

Rework META_TARGETS so that it automatically adds META_DEPS to the targets.

This will only be done if the target is defined, so if the target is
defined after bsd.sys.mk is included then it needs to manually add
${META_DEPS} still.

META_MODE: Simplify the META_COOKIE handling to use .USE/.USEBEFORE.

Extend it to other cases of meta mode cookies so they get the proper rm
cookie behavior when a .meta file detects it needs to rebuild and fails.

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.

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

Remove MAINTAINER= lines from individual Makefiles in favor of the
MAINTAINER file (which already had entries for sendmail).

Prevent a 'make SHARED=symlinks install' followed by 'make install' from
failing by removing the symlink before trying to install the actual files.

Drop support for COPY, -c has been the default mode of install(1)

Unbreak installworld. Revision 1.41 of src/usr.bin/xinstall/xinstall.c
made the usage here incorrect.

Note that the change to install may cause other things to break, such as
the advice in src/etc/defaults/make.conf:

# Compare before install
#INSTALL=install -C

If users actually use this, any ${INSTALL} -d invocations in an installworld
will also fail.

Do not change the directory permissions for the source area, just the
install area.

Install the sendmail cf building tools (contrib/sendmail/cf) in
/usr/share/sendmail/cf.
