Enable using the statically embedded blob from the kernel, if present. The KLD
loaded DTB takes precedence, but they are both recognized and handled in the
same way.

o This is disabled by default for now, and can be enabled using WITH_FDT at
build time.
o Tested with ARM and PowerPC.

- Only non-sliced bsdlabel style partitioning is currently supported (but provisions
are made towards GPT support, which should follow soon)
- Enable storage support in loader on ARM

This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).
Only netbooting is supported at the moment.

- extend ub_dev_read() and ub_dev_recv() so that the actual len and
all error codes can be passed and processed properly; unify behaviour of
these routines
- introduce syscall general error code (API_ESYSC)
- add new diag commands: devinfo, sysinfo for U-Boot-style details about the system
configuration
- better memory info summary
- style corrections

- It is opt-out for now so as to give it maximum testing, but it may be
turned opt-in for stable branches depending on the consensus. You
can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
It is harmless to steal the knob as SSP symbols have been provided
by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
(sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
libc will be automatically downgraded to -fstack-protector because it
breaks rtld otherwise.
- This option is unavailable on ia64.
Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.
Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).
This change effectively reverts the following CVS commit:
sys/boot/common/dev_net.c
revision 1.7
date: 2000/05/13 15:40:46; author: dfr; state: Exp; lines: +2 -1
Only probe network settings on the first open of the network device.
The alpha firmware takes a seriously long time to open the network device
the first time.
Also suppress excessive output while netbooting via loader, unless debugging.
While there, make sys/boot/uboot more style(9) compliant.

o Move the API prototypes to a separate header (glue.h)
o Allow the platform to hint libuboot about where to look
for the API signature. The uboot_address variable is
expected to be defined by the platform.
