Usually this function is called for appending some small files only
(like fs marks) but let's just make it more generic and capable of
handling bigger files easily. Increasing buffer to 1 KiB shouldn't hurt.

It was there in case of adding some "create" command options that should
be parsed before actually creating the output image. It seems we don't
need any at this point so let's drop this function for now.

There is no need to allocate buffer as big as the whole image in order
to calculate CRC32. It's enough to use small buffer and just read file
content block by block.

This requires changing this helper to accept initial/current CRC32
value as argument but it allows dropping duplicated (complex?) code
calculating the CRC32.

Without this the condition
if __BYTE_ORDER == __BIG_ENDIAN
was always true.
Thanks Szabolcs.

So far we got only one generic function accessing this table, but
implementing optimizations will require calculating crc32 in other code
parts as well.
