Modified Files:
        src/sys/kern: kern_malloc.c
        src/sys/sys: mallocvar.h param.h
        src/usr.bin/vmstat: vmstat.c

Log Message:
Extend struct malloc_type to count the number of active allocations
per size, and make vmstat report this information under the "Memory
statistics by type" display, which is only printed when the kernel
has been compiled with KMEMSTATS defined, like this:

Memory statistics by type                                Type  Kern
           Type InUse  MemUse HighUse   Limit   Requests Limit Limit Size(s)

Since struct malloc_type is user-visible and is changed, bump kernel
revision to 5.99.26.

While it is true that malloc(9) is in general on the path of slowly
being replaced by kmem(9) (kmem_alloc/kmem_free), there remains a
lot of points of usage of malloc/free, and this could aid in finding
any leaks.  (It helped finding the leak fixed in PR#42661.)

This was discussed with and somewhat hestitantly OKed by rmind@
