"env grep" - add support for regular expression matches
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.
