fd2366536d -fno-common broke kernhist since it used commons. 
Add a KERNHIST_DEFINE which is define the kernel history.
Change UVM to deal with the new usage.

8169e46991 move and rename the uvm history code out of uvm_stat to "kernhist". 
rename "UVMHIST" option to enable the uvm histories.

TODO:
- make UVMHIST properly depend upon KERNHIST
- enable dynamic registration of histories.  this is mostly just
  allocating something in a bitmap, and is only for viewing multiple
  histories in a merged form.


tested on amd64 and sparc64.

fbae48b901 Change "inline" back to "__inline" in .h files -- C99 is still too 
new, and some apps compile things in C89 mode. C89 keywords stay.

5b4c9f2016 rearrange struct uvm_history to put the struct simplelock at the end. 
This avoids problems with the kernel grovelling vmstat -u/-U when
using LOCKDEBUG, which changes the size of struct simplelock.
Replaced the original location of the simplelock with "int unused"
so that binary compatibility will be retained with old vmstat.

f63fe467c9 Add new history grovelling function uvm_hist() that takes a bitmask of 
histories to merge in cronological order.  currently, MAPHIST and
PDHIST are defined as 1 and 2 respectively.  passing a bitmask of 0
to uvm_hist() will dump all maps.

872181c2f2 A few changes to make it possible to read UVM histories from userland: 
- Protect option headers from inclusion if ! _KERNEL or if _LKM.
- Make sure struct uvm_history is always the same size (not dependent
  on NCPU).
- Add fmtlen and fnlen members to struct uvm_history_ent, which specify
  the lengths fo the fmt and fn strings.
- Add name, namelen, and a list entry to struct uvm_history.
- When a history is initialized, place it on the global list of all histories.
