zlib: Fix adler32_combine/4 and crc32_combine/4
Since our config.h is included in each source file in the zlib
directory, we must make sure that config.h is also included
every time zlib functions are called to ensure that definitions
of types are consistent.
zlib_drv.c did not include config.h, which caused problems on
a MacOS X Leopard system. What happened was that HAVE_UNISTD_H
was not defined when zlib.h was included. When unistd.h is not
known to exist, the type z_off_t will be set to a long (32 bits
on this platform). But when the zlib source files were compiled,
HAVE_UNISTD_H was defined, unistd.h would be included, and
z_off_t would be set to off_t (64 bits; defined in unistd.h).
As a result of the mismatch, calls to the adler32_combine() and
crc32_combine() would pass only 32 bits in the len2 argument when
64 bits were expected.
