We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.
Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

There are a number of places where U-Boot intentionally and legally
accesses physical address 0x0000, for example when installing
exception vectors on systems where these are located in low memory.
Add "cppcheck-suppress nullPointer" comments to silence cppcheck
where this is intentional and legal.

Curent U-Boot can boot zImage by use the "go" command.
But this is not right method. And this method can not set command-line
to linux kernel.
zimageboot sets command-line in environment of u-boot in linux kernel,
and provides function to boot it.
