.Split TTY in order to support both x86 and ARM.
.Add support for the TI 16750 UARTs on OMAP35x.
.Various other improvements:
.Kernel messages are printed using generic terminal write
functions. That is, they are no longer directly displayed
on the console.
.The console can now be displayed on any terminal. This
is configured by the "console={tty00,tty01,ttyc2,ttyc3,ttyc4}"
boot variable -- basically any valid /dev/tty* terminal.
.Cutify kernel messages with colors. Configured by
"kernelclr={1,2,3,4,5,6,7}" boot variable.
* Removing commands/tar
* Updated external/bsd/libarchive
* Adding external/bsd/libarchive/bin/tar compiled bsdtar instead
of just tar
* (tar is taken care of through the pax utility)

Add primary cache management feature to libminixfs as mfs and ext2
currently do separately, remove cache code from mfs and ext2, and make
them use the libminixfs interface. This makes all fields of the buf
struct private to libminixfs and FS clients aren't supposed to access
them at all. Only the opaque 'void *data' field (the FS block contents,
used to be called bp) is to be accessed by the FS client.
The main purpose is to implement the interface to the 2ndary vm cache
just once, get rid of some code duplication, and add a little
abstraction to reduce the code inertia of the whole caching business.
Some minor sanity checking and prohibition done by mfs in this code
as removed from the generic primary cache code as a result:
- checking all inodes are not in use when allocating/resizing
the cache
- checking readonly filesystems aren't written to
- checking the superblock isn't written to on mounted filesystems
The minixfslib code relies on fs_blockstats() in the client filesystem to
return some FS usage information.
* Add dummy driver to allow independent testing of mmcblk.
* Always build the mmc driver to prevent breakage.
* Allow to specify the mmc driver to be used at load time.

This is a security measure. We may want to bring back user access to
mounting and formatting media in the future, but this should be done
only once we are sure that this is safe from a security perspective.
As of this patch, df(1) no longer performs raw disk access; it
operates exclusively on mounted file systems. This also means
that df no longer needs to be setuid.
We have actually had lseek64 for quite a while now, so it's no longer
necessary to do horrible things to the partition table just to be able
to access large offsets into a device.
Also fix the compiler warnings in these commands.
- inherit a predefined set of system environment variables
(the current set of inherited variables is: ahci; acpi; no_apic);
- auto-adjust the default menu option when lines are auto-removed;
- add variable substitution support for /etc/boot.cfg.local;
- make default menu options in boot.cfg.local relative to itself,
allowing one to set the default to a menu option from this file.
. Removed the usage of 64 bit functions in top.c. Compiles successfully.
. Scaling 64 bit values to 32 bit is removed.
. Retain make64 instead of using | with shift.
. Add order cycling display
Introduce explicit abstractions for different mapping types,
handling the instantiation, forking, pagefaults and freeing of
anonymous memory, direct physical mappings, shared memory and
physically contiguous anonymous memory as separate types, making
region.c more generic.
Also some other genericification like merging the 3 munmap cases
into one.
COW and SMAP safemap code is still implicit in region.c.
- add "edit" menu option, to edit menu commands before executing them;
- add "menu" boot command, to return to the menu from the prompt;
- provide more line editing features when getting input;
- fix a few potential buffer overflows as a side effect.
The check_bsf() macro uses assert(mutex_trylock(&bsf_lock)) and
assumes bsf_lock is locked afterwards. This breaks when compiling
with NOASSERTS="yes". Also: macro to function transition.
