5d6fec5b63 Disable and lobotomize the kvm image reading swapinfo code, the kernel 
layout is about to change.

The sysctl based method still returns correct information.

5243b6799b Retire the SWIF_DUMP_TREE code, this is in the way for a rework of 
the swap_pager layout.

57e6d29b1e Remove all use of the LOG2() macro/inline, undoing some non-optimal cruft 
that crept in recently.  GCC will optimize the divides and multiplies for us.

42c43e6031 Make struct swblock kernel only, to make vm/swap_pager.h userland includable. 
Move struct swdevt from sys/conf.h to the more appropriate vm/swap_pager.h.
Adjust #include use in libkvm and pstat(8) to match.

e04a7c4ae5 Change this to support the new way swap device information is exported 
via sysctl, and clean up some style and (size_t != int) issues.

ae3a37ad44 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.

c4a7cdb3b6 Use kldsym(2) to lookup symbol values. This avoids the kvm_mkdb juggling 
and is module aware.  Yes, this means that kvm_nlist(3) will find symbols
in loaded modules.  The emulation of the nlist struct is pretty crude but
seems to work well enough for all the users in the tree that I found.

bd54ec1edf From rev. 1.12 of usr.sbin/pstat/pstat.c by phk: 
Reflect the fact that we do not swap on the first <dmmax> blocks of a
swapdev, to protect disklabels and other such magic stuff.
