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.
