env exists allows scripts to query whether an environment variable
exists. Enable by default as it adds only a trivial amount of code and
can be useful in scripts.

The "mtest" command is of little practical use (if any), and
experience has shown that a large number of board configurations
define useless or even dangerous start and end addresses. If not even
the board maintainers are able to figure out which memory range can be
reliably tested, how can we expect such from the end users? As this
problem comes up repeatedly, we rather do not enable this command by
default, so only people who know what they are doing will be
confronted with it.
As this changes the user interface, we allow for a grace period
before this change takes effect. For now, we make "mtest"
configurable through the CONFIG_CMD_MEMTEST variable, which is defined
in include/config_cmd_default.h; we also add an entry to
doc/feature-removal-schedule.txt which announces the removal of this
default setting in two releases from now, i. e. with v2013.07.

The editenv command can be used to edit an environment variable.
Editing an environment variable is useful when one wants to tweak an
existing variable, for example fix a typo or change the baudrate in the
'bootargs' environment variable.

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.

The CONFIG_CMD_ENV option controls enablement of the `saveenv` command
rather than a generic "env" command, or anything else related to the
environment. So, let's make sure the define is named accordingly.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

Derive three new files from cmd_confdefs.h:
config_bootp.h - Has BOOTP related config options, not commands
config_cmd_all.h - Has a CONFIG_CMD_* definition for every command
config_cmd_default.h - Has a CONFIG_CMD_* definition for default cmds.
For now, include "config_bootp.h" for compatability until all
users of it directly include it properly.
