Lionel Sambuc c3fc9df84a Adding ipc_ prefix to ipc primitives
* Also change _orig to _intr for clarity
 * Cleaned up {IPC,KER}VEC
 * Renamed _minix_kernel_info_struct to get_minix_kerninfo
 * Merged _senda.S into _ipc.S
 * Moved into separate files get_minix_kerninfo and _do_kernel_call
 * Adapted do_kernel_call to follow same _ convention as ipc functions
 * Drop patches in libc/net/send.c and libc/include/namespace.h
