While our copy of zlib is missing upstream commit 263b1a05b04e ("Allow
deflatePrime() to insert bits in the middle of a stream.") we do have
Z_FIXED support, and so the majority of the code changes in 5c44459c3b28
("Fix a bug that can crash deflate on some input when using Z_FIXED.")
apply here directly and cleanly. As this has been assigned a CVE, lets
go and apply these changes.

Drop inclusion of crc.h in common.h and use the correct header directly
instead.
With this we can drop the conflicting definition in fw_env.h and rely on
the crc.h header, which is already included.

We often need the requirement that compressing those memory range start
from 0, but the default deflate code in zlib prevent us to do this.
Considering the special case of uboot, that it could access all memory
range, it is reasonable to be able to also take the address space from 0
into compression.
