File chmlib-c99.patch of Package chmlib

Avoid implicit function declarations, for C99 compatibility

Include <arpa/inet.h> for inet_addr, <unistd.h> for close,
write. Define _LARGEFILE64_SOURCE so that <unistd.h> defines pread64.

This avoids build failures with future compilers which do not support
implicit function declarations by default.

Submitted upstream: <https://github.com/jedwing/CHMLib/pull/17>
