ccfb965433 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.

79e6a2c01e watch: Do not mess up the tty modes on early error.
Record the initial state earlier, so it is always safe to restore it.

One way this happens is if watch(8) is started by a user that does not have
access to /dev/snp. The result is "staircase effect" during later commands.

2e37c8eacb Convert the snp(4) driver to use cdevpriv.
Now we have a single /dev/snp device node, which can be opened by
watch(8) multiple times. Even though snp(4) will be dead as of next
week, it's nice having this in SVN, because:

- We may want to MFC it to RELENG_7.
- By the time we fix snp(4) again, it's already there, existing watch(8)
  binaries should already work.

Just like bpf(4), I'm adding a symlink from snp0 to snp to remain binary
compatible.

868f9ca26a Allow watch(8) to use more than 10 snp* devices. This limitation was purely
due to the way watch(8) looks for available snoop devices.

f8da56fda8 By default, the watch utility will attempt to open /dev/snp0, if
another process already has /dev/snp0 open, the snp(4) will return
EBUSY, in which case watch will try to open /dev/snp1..9. Currently
watch does not check errno to see if the failure was a result of EBUSY.

This results in watch making futile attempts to open snp0..snp9 even
though devices may not exist or the caller does not have permissions
to access the device.

In addition to this, it attempts to setup the screen for snooping even
though it may not ever get an snp device.

So this patch does two things
1) Checks errno for EBUSY, if open(2) fails for another reason
   print that reason and exit.
2) setup the terminal for snooping after the snp descriptor has
   been obtained.

should ever change, watch(8) would have broke because of a

3278021b94 Remove the sentence about only root being able to run watch(8). It
was never technically true (it's snp(4) that required root, not
watch(8)), and after snp.c 1.64, isn't even effectively true, since
who can run watch(8) depends on the permissions of the snp device(s).

1995d3a484 Add an -f option which allows one to specify a snp device to use.
Previously, watch would always use the first device it could
successfully open, but this isn't always desired.  Specifically, it
may not be desired during debugging (of snp), or if a particular snp
device has different permissions (which makes since after snp.c 1.64).
