* 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
