Use multiple flashproxy bridge lines
In comment:5:ticket:7153 I suggested using multiple bridge lines in the flashproxy configuration. The idea is that since flashproxy-client multiplexes multiple external connections, tor should have a hint that it can connect to the PT more than once. comment:2:ticket:10429 has the results of some tests showing slightly improved reliability with multiple bridge lines.
This patch doesn't cause flashproxy-client to make any additional external connections. It still sends just a single registration message at startup, and receives the same number of external proxy connections. The different is that the PT program will appear to tor to be more than a single bridge, so tor can connect to the PT multiple times and use more than one of the external connections.
This is the corresponding change in flashproxy upstream: https://gitweb.torproject.org/flashproxy.git/commitdiff/51bdfe59cad37a5f2ffdac3b5f40fe5e2f402a2e
