Make bridges publish additional ORPort addresses in their descriptor
I run Tor 0.2.4.17-rc as a bridge configured with multiple IPv4 addresses and one ORPort line for each, like so:
ORPort :443 ORPort :443 ... ORPort :443
When starting tor, the log will show that only is self-tested and a bridge descriptor is published:
[notice] Now checking whether ORPort :443 is reachable... (this may take up to 20 minutes -- look for log messages indicating success) [notice] Self-testing indicates your ORPort is reachable from the outside. Excellent. Publishing server descriptor.
Tor should publish bridge descriptors for all the available addresses and the bridge authorities should probably put them into pools of different confidentiality levels.
For clarity, the documentation should explain Tor's bandwidth allocation as configured with Relay(Bandwidth|Burst)Rate (per address or total).
