Brad Fitzpatrick 4aba86cc03 ipn/ipnserver: make Engine argument a func that tries again for each connection
So a backend in server-an-error state (as used by Windows) can try to
create a new Engine again each time somebody re-connects, relaunching
the GUI app.

(The proper fix is actually fixing Windows issues, but this makes things better
in the short term)

Implement rate limiting on log messages (#356)
Implement rate limiting on log messages

Addresses issue #317, where logs can get spammed with the same message
nonstop. Created a rate limiting closure on logging functions, which
limits the number of messages being logged per second based on format
string. To keep memory usage as constant as possible, the previous cache
purging at periodic time intervals has been replaced by an LRU that
discards the oldest string when the capacity of the cache is reached.
