Jonas 'Sortie' Termansen 05282c86d7 Fix fchownat(2) system call ABI on x86.
This system call has five arguments, of which one is a 64-bit uid_t, and
another is a 64-bit gid_t, which means that 7 registers are needed. However,
x86 only has 5 registers available for system calls. Wrap the system call
with a structure like with mmap(2).

Jonas 'Sortie' Termansen 02c6316e95 Remove kernel debugger, old kernel US layout and kernel symbol code.
The debugger has fallen behind and has become a maintenance burden.  It was
the only user of the old kernel US layout system, which is good to get rid
of.  The debugger didn't work with graphical output and was likely to
conflict with the new keyboard system if used, which no longer triggered it.
The kernel symbol code was removed to simplify the kernel.

The kernel debugger was an useful debugging feature, but it needs to be done
in a better way before it can be added back.

Jonas 'Sortie' Termansen 6725972e11 Fix LinkInodeInDir return value.
The callers expected it to return an int different than 0 on failure. The
link method returns different than 0 on failure. This actually worked by
lucky coincidence. Change the return type to int and 0 on success, and -1
on failure per popular demand.

Thanks to Meisaka Yukara for spotting this.

Jonas 'Sortie' Termansen ef45218660 Add S_ISGID and S_ISUID.
I originally left them out because Sortix doesn't have setuid and setgid
executable support, but this created considerable compatibility issues and
it is better to supply them as the mode bits still exist and can be set.

Jonas 'Sortie' Termansen 76bf0eb30c Remove String::Combine kernel function.
This function has followed me through a few projects for many years. It's
time to retire it. It's not too terribly well-written and it's mostly
replaced by the standard asprintf call. It's not even used in Sortix at the
moment.
