tools/env: allow to pass NULL for environment options

If users of the library are happy with the default, e.g. config file
name. They can pass NULL as the opts pointer. This simplifies the
transition of existing library users.
FIXES a compile error. since common_args has been removed by
a previous patch

tools/env: allow config filename to be passed via command line argument

When for example generating/manipulating SD card/eMMC images which
contain U-Boot and its environment(s), it is handy to use a given
configuration file instead of the compiled-in default one.
And since the default configuration file is expected under /etc
it's hard for an usual linux user account without special permissions
to use fw_printenv/fw_setenv for this purpose.
So allow to pass an optional filename via a new '-c' command
line argument.

Example:

$ ln -s fw_printenv tools/env/fw_setenv
$ cat fw_env.config
test.img 0x20000 0x20000
test.img 0x40000 0x20000

$ tools/env/fw_printenv -c ./fw_env.config fdt_file
fdt_file=imx28-duckbill.dtb

$ tools/env/fw_setenv -c ./fw_env.config fdt_file imx28-duckbill-spi.dtb

$ tools/env/fw_printenv -c ./fw_env.config fdt_file
fdt_file=imx28-duckbill-spi.dtb

This patch fixes getenvsize(), and thus also ensures that the
environment's CRC32 checksum is calculated correctly.
