musl/include/sys/shm.h
Rich Felker 07e865cc5a numerous fixes to sysv ipc
some of these definitions were just plain wrong, others based on
outdated ancient "non-64" versions of the kernel interface.

as much as possible has now been moved out of bits/*

these changes break abi (the old abi for these functions was wrong),
but since they were not working anyway it can hardly matter.
