gzip: Avoid use of u64
The gzip API uses the u64 type in it, which is not available in the host
build. This makes it impossible to include the header file.
We could make this type available, but it seems unnecessary. Limiting the
compression size to that of the 'unsigned long' type seems good enough. On
32-bit machines the limit then becomes 4GB, which likely exceeds available
RAM anyway, therefore it should be sufficient. On 64-bit machines this is
effectively u64 anyway.
Update the header file and implementation to use 'ulong' instead of 'u64'.
Add a definition of u32 for the cases that seem to need exactly that
length. This should be safe enough.
