. set 'done' once initialized so 32-bit read frc works,
thanks to keesj
. make sure the software-implemented upper 32 bit of the 64-bit
"tsc" value works OK by adding an assert in one of its calls

Generalize the usage of mmc_send_cmd function to allow
it to transfer data and remove direct invocations to
mmchs_send_cmd.

Clock configuration will be needed by other/future subsystems such as i2c.
Extract the functionality from libgpio and put it into it's own library.

- setlogin() not available
- softfloat needed in -lminc for arm
- libminc: we have to set LIBCDIR for the included files,
so use that instead of LIBCSRCDIR

. always keep reading data from uart so the interrupt is
not continually asserted if data is sent but no process
reads it
. increase tx & rx fifo trigger levels -> reduces the number
of interrupts necessary
. bigger rx/tx buffers

. unpause() and revive() can race - revive() can run during
a device i/o unblock, causing two sendnb()s to occur, and the
2nd one to fail
. this can easily happen when a process is blocking on tty and
is then killed by a signal - tty cancels the i/o and then
kills the process by a signal

. the default entry for disabled ttys for getty
in /etc/ttys is "", but init crashed on handling that
string.

. ignore interrupt (stop interrupt check loop) if
interrupt bit not set; limit loop too
. mask off other bits when testing bits in the status register
. this fixes rs232 output that would otherwise never get re-triggered
as too many bits were set in the status byte to match the
possibilities.

. let the dynamic linker use a real file mmap(), reverting
most of the minix-specific changes
. except for a fallback mode for systems or filesystems that
do not support mmap() on files
. make, grep: let them use mmap() too, with fallback

. test74 for mmap functionality
. vm: add a mem_file memory type that specifies an mmap()ped
memory range, backed by a file
. add fdref, an object that keeps track of FD references within
VM per process and so knows how to de-duplicate the use of FD's
by various mmap()ped ranges; there can be many more than there can
be FD's
. turned off for now, enable with 'filemap=1' as boot option

. libc: add vfs_mmap, a way for vfs to initiate mmap()s.
This is a good special case to have as vfs is a slightly
different client from regular user processes. It doesn't do it
for itself, and has the dev & inode info already so the callback
to VFS for the lookup isn't necessary. So it has different info
to have to give to VM.
. libc: also add minix_mmap64() that accepts a 64-bit offset, even
though our off_t is still 32 bit now.
. On exec() time, try to mmap() in the executable if available.
(It is not yet available in this commit.)
. To support mmap(), add do_vm_call that allows VM to lookup
(to ino+dev), do i/o from and close FD's on behalf of other
processes.

If present a file called .settings will be sourced when
calling the arm_sdimage.sh script. This allows to configure
the build setting for arm build without the need to specify
the flags each time arm_sdimage.sh is called.
For example to configure arm_sdimage.sh to target the
beaglebone put the following content in your .settings file.

The syslogd.pid file has moved from /usr/run to /var/run. The comments
in syslog.conf direct the user to restart syslogd using the old PID
file location. This patch updates the comment to match the code.

The previous test would return EFAULT as soon as the group pointer
was NULL, while it is sensible when the count is also 0.
In that case, the SETGROUP syscall is expected to clear all the
group entries as the new set is empty.
