FreeBSD — vendor/atf/dist configure Makefile.in, vendor/atf/dist/admin ltmain.sh install-sh

Import atf-0.21:

Released on October 23rd, 2014.

* Restored the atf(7) manual page to serve as a reference to all the other
  manual pages shipped by ATF.

* Added the -s flag to atf-sh to support specifying the shell interpreter
  to be used.

* Removed ATF_WORKDIR.  The only remaining consumers have been converted to
  use the standard TMPDIR environment variable.  As a benefit, and because
  Kyua forces the TMPDIR to live within the test case's work directory,
  any stale files left behind by ATF will be automatically cleaned up.

* Documented the environment variables recognized by each component in the
  relevant manual pages.  This information was lost with the atf-config(1)
  removal.

* Added a new "require.diskspace" metadata property to test cases so that
  they can specify the minimum amount of disk space required for the test
  to run.

* Renamed the atf-{c,c++,sh}-api(3) manual pages to atf-{c,c++,sh}(3) for
  discoverability purposes.  Symbolic links are provided for the time

FreeBSD — head/sbin/fsck_msdosfs dosfs.h boot.c, head/sys/boot/amd64/boot1.efi boot1.c

Make UEFI booting of 4Kn disks work:
      -        convert boot1.efi to corrrectly calculate the lba for what the
        media reports and convert the size based on what FreeBSD uses.
        The existing code would use the 512 byte lba and convert the
        size using 4K byte size.
      -        make fsck_msdosfs read the boot block as 4K so the read doesn't
        fail on a 4Kn drive since FreeBSD will error out parition reads
        of a block.  Make the bpbBytesPerSec check a multiple of 512 since
        it can be 512 or 4K depending on the disk.  This allows fsck to
        pass checking the EFI partition on a 4Kn disk.

To create the EFI file system I used:
        newfs_msdos -F 32 -S 4096 -c 1 -m 0xf8 <partition>
This works for booting 512 and 4Kn disks.

Caveat is that loader.efi cannot read the 4Kn EFI partition.  This isn't
critical right now since boot1.efi will read loader.efi from the ufs
partition.  It looks like loader.efi can be fixed via making some of the
512 bytes reads more flexible.  loader.efi doesn't have trouble reading
the ufs partition.  This is probably a simple fix.

I now have FreeBSD installed on a system with 4Kn drives and tested the
same code works on 512.

Port the TTM AGP backend to the FreeBSD agp driver and enable AGP support

Note: In PCI mode virtual addresses on the graphics card that map to system
RAM are translated to physical addresses by the graphics card itself.   In
AGP mode address translation is done by the AGP chipset so fictitious
addresses appear on the system bus.  For the CPU cache management to work
correctly when the CPU accesses this memory it needs to use the same
fictitious addresses (and let the chipset translate them) instead of using
the physical addresses directly.

Fix mbuf leak in IPv6 multicast code.
When multicast capable interface goes away, it leaves multicast groups,
this leads to generate MLD reports, but MLD code does deffered send and
MLD reports are queued in the in6_multi's in6m_scq ifq. The problem is
that in6_multi structures are freed when interface leaves multicast groups
and thread that does deffered send will not take these queued packets.
