Fix <fcntl.h> including <sys/stat.h> namespace pollution. POSIX allows <fcntl.h> to include <sys/stat.h>, but doesn't require it. There's little reason to do that, since they are separate headers, and <fcntl.h> just needs the mode_t constants. Fix the code accidentally relying on <fcntl.h> including <sys/stat.h>. The mode_t constants are now provided in their own kernel header <sortix/mode.h>. Additionally fix <sys/stat.h> pulling in all of <sys/types.h>, which is not allowed by POSIX, which only requires a few types to be declared. Fix the code accidentally relying on <sys/stat.h> including <sys/types.h>. Finally fix <dirent.h> pulling in <stdint.h> through <sortix/dirent.h>. The <sortix/__/dt.h> and <sortix/__/stat.h> headers are no longer required and their contents have been merged into <sortix/__/dirent.h>.

Standardize header include guards. This change makes all the standard library and kernel headers use header guards with a consistent scheme within the reserved namespace to avoid conflicts with non-standard-library-implementation code.

Implement file descriptor passing. This change refactors the Unix socket / pipe backend to have a ring buffer containing segments, where each segment has an optional leading ancillary buffer containing control messages followed by a normal data buffer. The SCM_RIGHTS control message has been implemented which transfers file descriptors to the receiving process. File descriptors are reference counted and cycles are prevented using the following restrictions: 1) Unix sockets cannot be sent on themselves (on either end). 2) Unix sockets themselves being sent cannot be sent on. 3) Unix sockets cannot send a Unix socket being sent on. This is a compatible ABI change.
