  Modified files:
    sys/alpha/include    mutex.h 
    sys/i386/include     mutex.h 
    sys/ia64/include     mutex.h 
    sys/kern             kern_mutex.c 
    sys/sys              mutex.h 
  Log:
  - Switch from using save/disable/restore_intr to using critical_enter/exit
    and change the u_int mtx_saveintr member of struct mtx to a critical_t
    mtx_savecrit.
  - On the alpha we no longer need a custom _get_spin_lock() macro to avoid
    an extra PAL call, so remove it.
  - Partially fix using mutexes with WITNESS in modules.  Change all the
    _mtx_{un,}lock_{spin,}_flags() macros to accept explicit file and line
    parameters and rename them to use a prefix of two underscores.  Inside
    of kern_mutex.c, generate wrapper functions for
    _mtx_{un,}lock_{spin,}_flags() (only using a prefix of one underscore)
    that are called from modules.  The macros mtx_{un,}lock_{spin,}_flags()
    are mapped to the __mtx_* macros inside of the kernel to inline the
    usual case of mutex operations and map to the internal _mtx_* functions
    in the module case so that modules will use WITNESS and KTR logging if
    the kernel is compiled with support for it.
