The main motivation for this change is that only Loris supports
multithreading, and Loris supports dynamic thread allocation, so the
number of supported threads can be implemented as a bit flag (i.e.,
either 1 or "at least as many as VFS has"). The ABI break obviates the
need to support file system versioning at this time, and several
other aspects are better implemented as flags as well. Other changes:
- replace peek/bpeek test upon mount with FS flag as well;
- mark libsffs as 64-bit file size capable;
- remove old (3.2.1) getdents support.

- pass in file system type through mount(2), and return this type in
statvfs structures as generated by [f]statvfs(2);
- align mount flags field with NetBSD's, splitting out service flags
which are not to be passed to VFS;
- remove limitation of mount ABI to 16-byte labels, so that labels
can be made larger in the future;
- introduce new m11 message union type for mount(2) as side effect.

This is a requirement for implementing calls such as getmntinfo(3).
VFS is now responsible for filling in some of the structure's fields.

The following types are modified (old -> new):
* _BSD_USECONDS_T_ int -> unsigned int
* __socklen_t __int32_t -> __uint32_t
* blksize_t uint32_t -> int32_t
* rlim_t uint32_t -> uint64_t
On ARM:
* _BSD_CLOCK_T_ int -> unsigned int
On Intel:
* _BSD_CLOCK_T_ int -> unsigned long
bin/cat is also updated in order to fix warnings.
_BSD_TIMER_T_ has still to be aligned.

clock_t is currently a signed type, but in NetBSD this is not the
case. As we plan on aligning our types we have to change this as this
prevents negative delta from being correctly used.

Created a new directory called bsp (board support package) to hold
board or system on chip specific code. The idea is the following.

The GPIO revision check assumed the major and minor revision numbers where
located at same location in the register. This is not true.

The bug in the offset correction code for the 'shrink region from
below' case can easily case an assert(foundregion->offset == offset)
to trigger (if the blocks are touched afterwards, e.g. on fork())
as the offsets become wrong. This commit is a fix & regression test.

We currently have a few of the POSIX tests failing because filemmap
is enabled by default. The working assumption is that these program
pass a pointer to the file server that points to a not yet loaded
data segment. When the file server tries to access that data it
therefore generates a pagefault and a call to itself it can not
handle because it is unable to first return the current call.

Make the kernel server and driver binaries indentical for the different
ARM platforms. We no longer need to define the AM335X or DM37XX flags
during compilation. The remaining differences are all located in u-boot.

During startup machine.board_id is now determined. The kernel can now
at runtime determine how to configure itself and does so.

On startup determine the board_id based on the board name
passed from u-boot. This code also export "board" for use
by userland using sysenv.

Put the boot arguments in uEnv.txt and not in cmdline.txt to allow
a more dynamic configuration of the system. We now also pass the
u-boot board_name parameter to the kernel.
Replaced the wget download of u-boot by a versioned git checkout
this allows us to better manage the u-boot and MLO version we ship
while still allowing us to build ofline.
This changes replaces the BASE_URL setting by U_BOOT_BIN_DIR and
also updates to a newer build of u-boot.
Export the board variable to userland using sysenv. This
allows rc-scrips to perform device specific initialisation.
The board variable follows the following pattern
[ARCH]-[ARCHVARIANT]-[VENDOR]-[BOARD]-[BOARDVARIANT]
We currently we support the following boards:
X86-I586-GENERIC-GENERIC-GENERIC
ARM-ARMV7-TI-BBXM-GENERIC
ARM-ARMV7-TI-BB-WHITE
ARM-ARMV7-TI-BB-BLACK

Modified the machine struct in include/minix/type.h to have an
additional field called board_id. This fields can be read out
by userland and drivers at runtime to enable automatic
configuration. The board_id field contains information about
the hardware architecture / board and such.
