env: allow to export only selected variables
New syntax: env export [-t | -b | -c] [-s size] addr [var ...] With this change it is possible to provide a list of variables names that shall be exported. Whenno arguments are given, the whole environment gets exported. NOTE: The new handling of the "size" argument means a change to the user API. Signed-off-by: Wolfgang Denk <wd@denx.de>
