Replaces the 256-byte ElG key in dests with padding.
Make all padding in dests and router identities a repeating random 32-byte pattern.

This will make gzipped dests and router identities be much smaller:
Dests: appx. 320 bytes smaller (82% reduction)
RIs: appx. 288 bytes smaller (74% reduction)

Expected to primarily benefit database store messages and streaming SYNs.
Does not rekey or affect existing destinations or router identities.
Testers running this patch may be identifiable via transient destinations.
New installs with this patch will be identifiable via router identities.

This also will significantly speed up Destination creation as
we will no longer generate an ElG keypair.

Tested for several months.
