Replace ioctl with fcntl, fix ioctlsocket calls (64-bit fix)

[GravisZro]

These take two different types of arguments but worked in the past due to long being 32-bit.

Description

The ioctl argument for UNIX systems is int* while the ioctlsocket argument for Windows is unsigned long*. On 32-bit systems theses coincided so no problems but not on 64-bit. However, the behavior of ioctl calls is non-standard which is why code should use fnctl.
