Nit: OS_POSIX, for consistency with the comment and the .cc file?  Or should
this decl just go in ipc_channel_posix.h?

Done to change the macro.
ipc_channel_posix.h seems to provide an implementation of IPC::Channel internal
structure for posix?

+// On POSIX an IPC::Channel wraps a socketpair() with set some attributes
+// (such as non-blocking mode). This returns raw FD #s for the pair, which
+// allows us to pass file descriptors between processes (such as between
+// a plugin process and the browser process) before actual initialization
+// of IPC server Channel instance.
+bool SocketPair(int* fd1, int* fd2);
