008d7c831f 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.

b619f0c747 Revert r267233 for now. PIE support needs to be reworked.
1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
   build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
   where it never would work anyhow, such as csu or loader. This suggests
   there may be better ways of adding support to the tree. Many of these
   cases can be fixed such that -fPIE will work but there is really no
   reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
   really building libraries but have been using bsd.prog.mk because the code
   is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
   been needed.

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

989e2c6000 In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.
This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.

Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]

Mark known build failures as NO_PIE for now.

The only known runtime failure was rtld.

the queue is not 'lpc stop'-ed.  In that situation `lpq' will

716dc0a601 The scandir(3) function expects fourth parameter, compar, be in type of:
int (*compar)(const struct dirent **, const struct dirent **)

The current code defines sortq() to accept two void *, then cast them
to const struct dirent **.  Because the code does not really need this
cast, we can eliminate the casts by changing the function prototype
to match scandir(3) expectation.

da4e70cf9a In preparation for raising NGROUPS and NGROUPS_MAX, change base
system callers of getgroups(), getgrouplist(), and setgroups() to
allocate buffers dynamically.  Specifically, allocate a buffer of size
sysconf(_SC_NGROUPS_MAX)+1 (+2 in a few cases to allow for overflow).

This (or similar gymnastics) is required for the code to actually follow
the POSIX.1-2008 specification where {NGROUPS_MAX} may differ at runtime
and where getgroups may return {NGROUPS_MAX}+1 results on systems like
FreeBSD which include the primary group.

In id(1), don't pointlessly add the primary group to the list of all
groups, it is always the first result from getgroups().  In principle
the old code was more portable, but this was only done in one of the two
places where getgroups() was called to the overall effect was pointless.

Document the actual POSIX requirements in the getgroups(2) and
setgroups(2) manpages.  We do not yet support a dynamic NGROUPS, but we
may in the future.

4b659b5a65 Changes which rewrite 'lpc topq', and which add 'lpc bottomq'. These
reflect much valuable feedback from wollman.  More details on the new
'lpc topq' are in the log message for revision 1.2 of lpc/movejobs.c.

The previous implementation of 'lpc topq' is available as 'lpc xtopq',
in case there are any problems noticed in the new implementation.  If
there are no problems with this version, a later update will remove the
'lpc xtopq' command.

075d7239bd Add a nearly complete rewrite of the lpc command 'down'. The only user-
visible change should be that more than one queue can now be specified,
if one uses the '-msg' parameter to separate the list of queues from the
status message to set.

The previous implementation of 'down' remains available as the command
'xdown', available for instant fallback if there seems to be anything
wrong with the new one.  If no one reports a problem after a few weeks,
then a later update will remove 'xdown'.

1c055fbea9 Almost complete rewrite of the lpc commands 'abort', 'enable', 'disable',
'restart', 'start', 'stop' and 'up'.  These are commands which mainly
just alter the access bits on the lock-file of a queue, and they all
now use a central routine to do that.  This reduces the amount of code
that is run as the priv userid, and eliminates a number of cases where
error messages were written while that priv uid was in effect.

As far as users are concerned, there should be no noticable difference
in the new versions.  In case there *is*, the previous implementations
are still there as 'xabort', 'xenable', etc, so they are available for
instant fallback.  If no one reports a problem after a few weeks, then
a later update will remove those x-commands.

f06e6295c8 My recent changes to add the ctl_renametf routine assumed that print job
control-files will always start with 'cfA*'.  It turns out that some
implementations of lpd (such as solaris) may send a control file which
starts with 'cfB*', or really 'cf<anyLetter>*'.  Although such filenames
are very odd, we did used to accept them.  This changes ctl_renametf to
work correctly with them, and fixes up 'lpc clean' to match.
