e1619d123e Only print the errno string in case sysctl(3) does not file with ENOENT 
This reduces the noise in error reporing from sysctl(8):

Before:
$ sysctl bla=something
sysctl: unknown oid 'bla': No such file or directory

After:
$ sysctl bla=something
sysctl: unknown oid 'bla'

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.

89871cdeb6 - Add a new structure type for the ACPI 3.0 SMAP entry that includes the 
optional attributes field.
- Add a 'machdep.smap' sysctl that exports the SMAP table of the running
  system as an array of the ACPI 3.0 structure.  (On older systems, the
  attributes are given a value of zero.)  Note that the sysctl only
  exports the SMAP table if it is available via the metadata passed from
  the loader to the kernel.  If an SMAP is not available, an empty array
  is returned.
- Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8)
  binary to format the SMAP structures in a readable format similar to
  the format found in boot messages.

9ecd2e32cd Allow sysctl to filter boot and runtime tunables. 
Add the following flags to sysctl:
 -W  - show only writable sysctls
 -T  - show only tuneable sysctls

This can be used to create a /var/run/sysctl.boot to
compare set tunables versus booted tunables.

f8e4b4ef49 sysctl(8) should use the CTLTYPE to determine the type of data when 
reading.  (This was already done for writing to a sysctl).  This
requires all SYSCTL setups to specify a type.  Most of them are now
checked at compile-time.

Remove SYSCTL_*X* sysctl additions as the print being in hex should be
controlled by the -x flag to sysctl(8).
