MINOR: stream: report the list of active filters on stream crashes

Now we very rarely catch spinning streams, and whenever we catch one it
seems a filter is involved, but we currently report no info about them.
Let's print the list of enabled filters on the stream with such a crash
to help with the reports. A typical output will now look like this:

  [ALERT] 121/165908 (1110) : A bogus STREAM [0x7fcaf4016a60] is spinning at 2 calls per second and refuses to die, aborting now! Please report this error to developers [strm=0x7fcaf4016a60 src=127.0.0.1 fe=l1 be=l1 dst=<CACHE> rqf=6dc42000 rqa=48000 rpf=a0040223 rpa=24000000 sif=EST,10008 sib=DIS,80110 af=(nil),0 csf=0x7fcaf4023c00,10c000 ab=0x7fcaf40235f0,4 csb=(nil),0 cof=0x7fcaf4016610,1300:H1(0x7fcaf4016840)/RAW((nil))/tcpv4(29) cob=(nil),0:NONE((nil))/NONE((nil))/NONE(0) filters={0x7fcaf4016fb0="cache store filter", 0x7fcaf4017080="compression filter"}]

This may be backported to 2.0.
