[Linphone-developers] [oRTP] fix HP-UX-related #define's & build on more os-arch without warnings

[Francois-Xavier 'FiX' Kowalski]

Hello Linphone developpers,

just ckin'ed:

- drop    HOST_IS_HPUX     &    TARGET_IS_HPUXKERNEL    macros    (use
 compiler-provided __hpux & user-provided _KERNEL)
- use X/Open socklen_t rather than int, to not break 64-bits MSB-first
 processes (32-bits & 64-bits LSB are not affected by this issue)
- HP-UX link with  -lxnet (link counter-part of _XOPEN_SOURCE_EXTENDED
 compilation directive). Will allow oRTP to work on LP64/MSB-first.

Now build without warnings on:

- linux/x86/ilp32
- linux/ia64/lp64
- hpux/hppa/ilp32
- hpux/ia64/ilp32
