Makefiles are evaluated without building things. In a normal build,
the prerequisites would be built, and CC would be an actual thing. In
an INDEX build, though, they don't exists. Redirect stderr to get rid
of annoying messages, and assume that the compiler version is 0 if the
actual compiler can't tell us. Do this in preference to guessing based
on numbers because gcc410 might be 4.10, or 4.1.0 and without
carefully crafted special knowledge we differentiate between them
easily (also ming-gcc has no clues at all). Elsewhere, don't trust
the compiler version if it is 0.
The CUSE library is a wrapper for the devfs kernel functionality which
is exposed through /dev/cuse . In order to function the CUSE kernel
code must either be enabled in the kernel configuration file or loaded
separately as a module. Currently none of the committed items are
connected to the default builds, except for installing the needed
header files. The CUSE code will be connected to the default world and
kernel builds in a follow-up commit.
The CUSE module was written by Hans Petter Selasky, somewhat inspired
by similar functionality found in FUSE. The CUSE library can be used
for many purposes. Currently CUSE is used when running Linux kernel
drivers in user-space, which need to create a character device node to
communicate with its applications. CUSE has full support for almost
all devfs functionality found in the kernel:
- kevents
- read
- write
- ioctl
- poll
- open
- close
- mmap
- private per file handle data

the UART FIFO.
The emulation is constrained in a number of ways: 64-bit only, doesn't check
for all exception conditions, limited to i/o ports emulated in userspace.
Some of these constraints will be relaxed in followup commits.

the proper ICWx initialization sequence. It assumes, probably correctly, that
the boot firmware has done the 8259 initialization.
Since grub-bhyve does not initialize the 8259 this write to the mask register
takes a code path in which 'error' remains uninitialized (ready=0,icw_num=0).
Fix this by initializing 'error' at the start of the function.
problem with broken in-tree builds (which are used far more
pervasively than I'd known outside the tree). However, weird results
may now happen if at any point in the tree above you there happens to
be a directory that has subdirectory of share/mk, as unpredictable
results will follow. This was considered the lessor of the two evils,
at least for now. In the future this will be removed again when the
underlying issues are resolved.
shared flag is set on normal-memory mappings made via pmap_kenter() for SMP.
The "shared flag" part of this change isn't obvious from the diff, here's
the deal... by using the array of preformatted page table entry templates
instead of constructing the PTE from scratch, we automatically get the
right attribute bits set for both caching and shared.

an embedded newline appearing within the options string surrounded by
double-quotes. Rework the logic that goes into setting dataset options on
the root pool dataset while we're here -- added two new variables (which
can be altered via scripting) ZFSBOOT_POOL_CREATE_OPTIONS and also
ZFSBOOT_BOOT_POOL_CREATE_OPTIONS for setting pool/dataset attributes at
the time of pool creation. The former is for setting options on the root
pool (zroot) and the latter is for setting options on the optional separate
boot pool (bootpool) implicitly enabled when using either GELI or MBR. The
default value for the root pool variable (ZFSBOOT_POOL_CREATE_OPTIONS) is
"-O compress=lz4 -O atime=off" and the default value for separate boot pool
variable (ZFSBOOT_BOOT_POOL_CREATE_OPTIONS) is NULL (no additional options
for the separate boot pool dataset).

- Use ASSUME_ALWAYS_YES=YES instead of ASSUME_ALWAYS_YES=1
since pkg-1.3 expects "yes" or "true" values.
- Before exporting PKG_ABI, strip extra characters from what
is parsed from 'pkg -vv'. This causes problems further down
when creating the packages directory for inclusion on the
dvd1.iso. Previously PKG_ABI would be 'freebsd:9:x86:64',
but now is '"freebsd:9:x86:64";' in pkg-1.3
