  Modified files:
    lib/libkvm           kvm_getswapinfo.c 
  Log:
  Adapt libkvm_getswapinfo() to make use of recently committed vm and swap
  sysctls exporting swap information.  When running on a live kernel,
  the sysctl's will now be used instead of kvm_read, allowing consumers of
  this interface to run without privilege (setgid kmem).  Retain the
  ability to run on coredumps, or on a kernel using kmem if explicitly
  pointed at one.
  
  A side effect of this change is that kvm_getswapinfo() is faster now in
  the general case. If the SWIF_DUMP_TREE flag is given (pstat -ss does
  this), the radix tree walker, which still uses kvm_read in any case, is
  invoked, and therefore does require privilege.
