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>.

This is not sufficient. The operator new calls are dangerous right now
because they throw exceptions (not handled) on error instead of returning
NULL. This needs to be changed to operator new nothrow instead.
This cleans up constructors so fields are initialized in the same order they
are declared in. This makes it trivial to spot accidentally uninitialized
fields.
This fixes a minor argument parsing bug when the mount path isn't set, but
fortunately argv[argc] is NULL and we wanted to set it to NULL anyway.
This prevents excessively large block sizes from being used.
This improves inode value range checks in the fsmarshall code. Inode 0 is
not a valid inode. The new code for this is also simpler.
This prevents creating links with names larger than 255 bytes.
This adds a check to ensure inodes don't overflow the hardlink count.
This ensures the dirent filetype is only set if supported.
