As the code currently stands, we first check that the length of the
given command line, along with ip_str/mac_str along with an additional 1
for the NULL termination will fit within the buffer we have, and if not,
we return an error. The way this code was originally written however
left Coverity "unhappy" due to using strcat rather than strncat.
Switching this to strncat however causes clang to be unhappy that we
aren't enforcing the "1" portion within strncat. Rather than further
re-work the code to include a "- 1" in this case as well, make the
strcat code only be done within the else side of the length test. This
keeps both clang and Coverity happy.

For the initrd portion of handling our bootm arguments we do not have a
sufficiently long enough buffer for some improbable 64bit cases. Expand
this buffer to allow for a 64bit address and almost 256MB initrd to be
used. Make use of strncpy/strncat when constructing the values here
since we know what the worst case valid values are, length wise.
Similarly for bootargs themselves, we need to make use of strlen/sizeof
and strncpy/strncat to ensure that we don't overflow bootargs itself.

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.

When FIT image is used, a single image provides kernel, device
tree and optionally ramdisk. Argc and argv need to be adjusted
to support this.
Test cases:
1. Booting with legacy images
2. Booting with legacy images without initrd
3. Booting with FIT image
Test commands:
1. pxe get && pxe boot
2. sysboot

Now that they are in their own directory, we can remove this prefix.
This makes it easier to find a file since the prefix does not get in the
way.
