bridge: Optimize trunk port common case.

Profiling with qprof showed that bitmap_set_multiple() and bitmap_equal()
were eating up quite a bit of CPU time during bridge reconfiguration (up
to about 10% of total runtime).  This is completely avoidable in the common
case where a port trunks all VLANs, where we don't really need a bitmap at
all.  This commit implements that optimization.
