cmd_nvedit.c: Add env exists command

2013-11-08T14:38:24+00:00

env exists is a way to test (in hush) if an environment variable
exists.  A workaround existed using printenv but this new command
doesn't require all the stdout/stderr redirection to prevent
printing information to the screen.

Example:
$ set testexists 1
$ env exists testexists && echo "yes"
yes
$ env exists testexists || echo "no"
$ set testexists
$ env exists testexists && echo "yes"
$ env exists testexists || echo "no"
no
$

"env grep" - add support for regular expression matches

2013-05-01T20:24:00+00:00

When CONFIG_REGEX is enabled, the new option "-e" becomes available
which causes regular expression matches to be used.  This allows for
example things like these:

- print all MAC addresses:

	=> env grep -e eth.*addr
	eth1addr=00:10:ec:80:c5:15
	ethaddr=00:10:ec:00:c5:15

- print all variables that have at least 2 colons in their value:

	=> env grep -v -e :.*:
	addip=setenv bootargs ${bootargs} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
	panic=1
	eth1addr=00:10:ec:80:c5:15
	ethaddr=00:10:ec:00:c5:15
	ver=U-Boot 2013.04-rc1-00289-g497746b-dirty (Mar 22 2013 - 12:50:25)

etc.

"env grep" - add options to grep in name, value, or both.

2013-05-01T20:24:00+00:00

Add options to "env grep" command:

-n : search only the envrironment variable names
-v : search only their values
-b : search both names and values (= default)

An option "--" will stop parsing options, so to print variables that
contain the striing "- " please use:

	env grep -- "- "

Or to print all environment varioables which have a '-' in their name,
use:

	env grep -n -- -

"env grep" - reimplement command using hexport_r()

2013-05-01T20:24:00+00:00

Also drop hstrstr_r() which is not needed any more.
The new code is way more flexible.

hashtable: preparations to use hexport_r() for "env grep"

2013-05-01T20:24:00+00:00

The output of "env grep" is unsorted, and printing is done by a
private implementation to parse the hash table.  We have all the
needed code in place in hexport_r() alsready, so let's use this
instead.  Here we prepare the code for this, without any functional
changes yet.

Add getenv_hex() to return an environment variable as hex

2013-05-01T15:17:21+00:00

This conversion is required in a number of places in U-Boot. Add a
standard function to provide this feature, so we avoid all the different
variations in the way it is coded.
