Make geom_label(4) resize-aware.  This fixes a situation when "gpart resize"
would resize a partition, but label providers - e.g. /dev/gptid/XXX - would
stay the same size.

Don't build krping.ko, iw_cxgb.ko, and iw_cxgbe.ko, if MK_OFED=no
(the default).  They build, but are unloadable, due to missing ibcore.ko.

sh: Remove one syscall when waiting for a foreground job.

The getpgrp() call is unnecessary: if there is no job control then the
result was not used at all and if there is job control then we are not a
subshell and our process group ID is equal to our process ID (rootpid).

Improve XHCI stability. When a command timeout happens, the command
should be aborted else the command queue can stop. Refer to section
"4.6.1.2" of the XHCI specification.

Add atse(4), a driver for the Altera Triple Speed Ethernet MegaCore.

The current driver support gigabit Ethernet speeds only and works with
the MegaCore only in the internal FIFO configuration in the soon to be
open sourced BERI CPU configuration.

MFP4: 1136252

Add an option ATSE_CFI_HACK to allow memory mapped CFI devices to have
their address range allocated sharable so that atse(4) can find it's
Ethernet address in the expected location.

We intend to remove this hack once the BERI platform has a loader.
There's no need to guard pmap_extract(), it won't be called until well after
the VM has been properly initialized.

Corrects the Kirkwood dreamplug to use
the right register for power managment. It
was incorrectly using the clock register
which also caused the status to be the
opposite of what it is supposed to be.
1 - its disabled
0 - its enabled

Clearly split the logic to build ATF and plain tests apart.

This change introduces a new plain.test.mk file that provides the build
infrastructure to build test programs that don't use any framework.
Most of the code previously in bsd.test.mk moves to plain.test.mk and
atf.test.mk is extended with the missing pieces.

In doing so, this change pushes all test program building logic to the
various *.test.mk files instead of trying to reuse some tiny bits.
In fact, this attempt to reuse some definitions makes the code harder
to read and harder to extend.

The clear benefit of this is that the interface of bsd.test.mk is now
clearly delimited.

Add the automatic generation of Atffile files.

These are only used by the deprecated atf-run and atf-report tools.
Generating them is easy and provides a mechanism for people to
experiment with these tools if they wish.

But, because these tools and files are deprecated, doing this only
happens if the user has explicitly set ALLOW_DEPRECATED_ATF_TOOLS
to yes.

Add the automatic generation of Kyuafile files.

These files are generated from bsd.test.mk because kyua is able to run
test programs implemented using different libraries/frameworks.  In
order to make this possible, this change also extends the various
*.test.mk file to explicitly indicate the interface of every test
program.
