Stop linking to libl by specifying we do not need yywrap

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.

Sync apmd(8) with DragonflyBSD, bringing WARNS to 3

Reviewed by: ed (partial, long time ago)

The last big commit: let usr.sbin/ use WARNS=6 by default.

Mark APM manpages as i386-only.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Remove GCC'isms in CFLAGS.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

Don't forget to clean y.output. Most files generated by yacc are cleaned
automatically, but not this one.

Fixed some style bugs.

$Id$ -> $FreeBSD$

This commit was generated by cvs2svn to compensate for changes in r48730,
which included commits to RCS files with non-trunk default branches.

The apmd package provides a means of handling various APM events from
userland code. Using apmd.conf, the apmd(8) configuration file, you
can select the APM events to be handled from userland and specify the
commands for a given event, allowing APM behaviour to be configured
flexibly.

Have Fun!
