Replace hlt with halt()

There were instances of unneeded arch/hlt.h includes,
    various hlt() calls that weren't supposed to exit (but
    might have) and various forms of endless loops around
    hlt() calls.

All these are sorted out now: unnecessary includes are
    dropped, hlt() is uniformly replaced with halt() (except
    in assembly, obviously).
