base: add helpers for sending/receiving file descriptors.
Almost all of the uses of cmsg(3) in our source tree are wrong in at
least one of the following ways:
- not aligning the cmsg buffer
- leaking fds if more fds are received than expected
- blindly dereferencing CMSG_DATA without checking the header
- using CMSG_SPACE instead of CMSG_LEN for .cmsg_len
- using CMSG_LEN instead of CMSG_SPACE for .msg_controllen
- using a length specified in number of fds instead of bytes
Implement wrapper functions that implement this dumpster fire of an
API correctly.
