Summary:                    [patch] Framehooks ast_indicate_data Incorectly uses
"read" this should be "write"
Description: 
A framehook has 2 events relating to frames read/write

a frame hook on a bridged channel can look at the write events to see the
packets coming into [read] on the peer.

the problem with control frames is they are not sent across the bridge
using a ast_write but a ast_indicate_data so to see these packets framehook
events are triggered in ast_indicate_data ... these are WRITE not READ
events and causes most peculiar results ...

in addition there is no certainty a AST_FRAME_CONTROL will be sent back
perhaps a AST_FRAME_NULL or someother frame .... i add a sanity check ...

Make indicate/control frames WRITE events on framehooks.  Also, if a
framehook
returns a non-control frame, don't forward it to the channel.
