[Port-solaris] VFS stats for AFS client

[Robert Milkowski]

Hi,

 Just to let you know - Andrew recently pushed "SOLARIS: Support VSW_STATS".
What it actually does it enables in Solaris collection of standard VFS stats
and it also makes fsinfo::: DTrace probes fire for AFS file system.

For example:

$ fsstat /ms 1
new  name   name  attr  attr lookup rddir  read read  write write
file remov  chng   get   set    ops   ops   ops bytes   ops bytes
    0     0     0 10.5K     0   173K   939 20.7K 72.8M     0     0 /ms
    0     0     0     0     0      0     0     0     0     0     0 /ms
