(1) renamed adler32.c -> zadler32.c, zcrc32c -> zcrc32.c

(2) zconf.h:
    - added _LP64 to make uLong a 32-bit int on 64-bit platform
    uLong -> 32-bit int

--------------------------

<
< #ifdef _LP64
< typedef unsigned int  uLong;  /* 32 bits or more */
< #else
426d394
< #endif
--------------------------

(3) updated crc32.c/crc32(), crc32_z()
   unsigned long      -> uLong

--------------------------
