Fix a SFBUF memory leak in sendfile().  We were not properly tracking
references which would lead to SFBUFs not getting freed when two or more
sendfile()'s are operating on the same file at the same time (e.g. parallel
ftp downloads of the same file).

Get rid of the sf_buf->aux1 and aux2 hacks for sendfile.

Add a sysctl to allow the number of free SFBUFs to be monitored.
