Ported disk free space checking code to work on Solaris.
On Solaris, using f_bsize provided a value that is apparently much larger
than the real block size. The solaris docs for statvfs say
f_bsize is the "preferred" file system block size, and I guess the
filesystem prefers larger blocks, but uses smaller ones or something.
The docs also say that f_frsize is the "fundamental" block size.
Switched to using f_frsize on Linux and kFreeBSD too, since I guess
f_bsize could in theory vary the same way there too. Assuming that Solaris
is not violating the posix spec, I guess the linux man page for statvfs
is not as well written and I misunderstood it.
