These are the fixes that we need to add to the 0.29-amq branch to then be built for the AMQ Clients 2.5.1 release (all to be cherry-picked from master):

PROTON-2116 - python memory leak

• one checkin upstream by Cliff on Oct 4

PROTON-2140 - proton-c has very high memory footprint for links
(4 total checkins)

• 1 by Gordon - Nov 20
• 3 more by Andrew on Nov 25

PROTON-2146: reduce memory per connection

• one checkin by Cliff on Nov 25
