input_stream: use "goffset" instead of "off_t"
The "off_t" type may change when you enable or disable large file support on 32 bit platforms. This caused severe ABI problems within MPD when we enabled LFS for the first time: two sources included config.h and sys/types.h in different order, and had different off_t sizes - leading to memory corruption because of ABI incompatibility. This patch attempts to get rid of all public "off_t" uses: it removes "off_t" from the input_stream ABI/API, and switches to GLib's 64 bit "goffset" type. This may hurt 32 bit embedded platforms a tiny bit, but that's not even measurable.
