Here it is again - slightly modified & smaller:
  - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0)
  - README.dns is added
  - syntax is changed (now takes a third option, the env var to store
    the result in)
  - add a random port() function in net.c
  - sort Makefile in ./net/Makefile
  - dns just returns unless a env var is given
  - run through checkpatch, and clean up style issues
  - remove packet from stack
  - cleaned up some comments
  - failure returns much faster (if server responds, don't wait for
    timeout)
  - use built in functions (memcpy) rather than byte copy.

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt

According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.

This patch prepares this change and starts a 6 month transition
period as follows:

- The new "source" command has been added, which implements exactly
  the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
  new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
  have *not* been adapted yet; these will be renamed resp. removed in
  a separate patch when the support for the "autoscr" command get's
  finally dropped.

Remove command name from all command "usage" fields and update
common/command.c to display "name - usage" instead of
just "usage". Also remove newlines from command usage fields.

When CONFIG_SYS_HUSH_PARSER is defined network download
commands with 1 argument in the format 'tftp "/path/file"'
do not work as expected. The hush command parser strips
the quotes from "/path/file" which causes the network
commands to interpret "/path/file" as an address
instead of the intended filename.

The previous check for a leading quote in netboot_common()
was replaced with a check which ensures only valid
numbers are treated as addresses.

cmd_net.c command descriptions were updated to describe the optional
hostIPaddr argument.  The dhcp command help message was also updated
to more closely reflect the other commands in cmd_net.c

autoscript() routine is updated to accept second argument, which
is only used for FIT images and provides a FIT subimage unit name.

autoscript() routine callers must now pass two arguments. For
non-interactive use (like in cmd_load.c, cmd_net.c), new environment
variable 'autoscript_uname' is introduced and used as a FIT
subimage unit name source.

autoscript command accepts extended syntax of the addr argument:
addr:<subimg_uname>
