Joshua Peraza a11243e8f1 linux: add wrappers for send/recvmsg 
sendmsg() and recvmsg() are complicated to use. Refactor their usage
into functions with a simpler, tested interface and use those instead.
This also adds CreateCredentialSocketpair() to create a pair of
connected sockets with SO_PASSCRED set. This option should be set
before the possibility of any calls to sendmsg() with the socket pair
to avoid race conditions in properly setting credentials.

Also update the handler to use Strategy::kNoPtrace (which causes the
crash dump to fail without breaking the socket connection) if the
credentials were invalid, which can happen if SO_PASSCRED was set after
the call to sendmsg() or if the sending process does not exist in this
namespace.
