Add versioning & tests, migrate db files (#1293)
We are preparing for the release of this to general public, so a few
things have been added:

1) Add versioning for bundles, and make refresh interval configurable
2) Move files to installationID so no metadata is leaked
3) Re-key using user password db

Upgrade geth 1.8.17 plus add metrics during compilation time (#1273)
This commit updates geth to 1.8.17 and adds a possibility to enable metrics during compilation time.

The cascade of issues forced us to upgrade geth to 1.8.17 in order to allow enabling metrics during compilation time. 1.8.17 introduced `NodeID` refactoring and `enode` package which affected our peers pool and integration with Discovery V5.

Add enabling/disabling of installations (#1264)
This commit adds a list new table, installations, which is used to keep
track of which installation are active for a given identity key.

In general, we limit the number of installation that we keep
synchronized to 5, to avoid excessive usage of resources.

Any installation coming from our own identity, will have to be manually
enabled, otherwise we trust the other peer has correctly paired their
devices.

We use a timestamp to decide which installations to keep synchronized as
a logical clock would have make the creation of the bundle more
complicated, but this can always be converted to a logical clock at
later stages without breaking compatibility.

Change handling of skipped/deleted keys & add version (#1261)
- Skipped keys

The purpose of limiting the number of skipped keys generated is to avoid a dos
attack whereby an attacker would send a large N, forcing the device to
compute all the keys between currentN..N .

Previously the logic for handling skipped keys was:

- If in the current receiving chain there are more than maxSkip keys,
throw an error

This is problematic as in long-lived session dropped/unreceived messages starts
piling up, eventually reaching the threshold (1000 dropped/unreceived
messages).

This logic has been changed to be more inline with signals spec, and now
it is:

- If N is > currentN + maxSkip, throw an error

The purpose of limiting the number of skipped keys stored is to avoid a dos
attack whereby an attacker would force us to store a large number of
keys, filling up our storage.

Previously the logic for handling old keys was:

- Once you have maxKeep ratchet steps, delete any key from
currentRatchet - maxKeep.

This, in combination with the maxSkip implementation, capped the number of stored keys to
maxSkip * maxKeep.

The logic has been changed to:

- Keep a maximum of MaxMessageKeysPerSession

and additionally we delete any key that has a sequence number <
currentSeqNum - maxKeep

- Version

We check now the version of the bundle so that when we get a bundle from
the same installationID with a higher version, we mark the previous
bundle as expired and use the new bundle the next time a message is sent

Make whisper tolerant to local time skews (#864)
This change adds adds an ability to use different source of time for whisper:

when envelope is created it is used to set expiry
to track when envelope needs to be expired
This time is then used to check validity of the envelope when it is received. Currently If we receive an envelope that is sent from future - peer will get disconnected. If envelope that was received has an expiry less then now it will be simply dropped, if expiry is less than now + 10*2 seconds peer will get dropped.

So, it is clear that whisper depends on time. And any time we get a skew with peers that is > 20s reliability will be grealy reduced.

In this change another source of time for whisper will be used. This time source will use ntp servers from pool.ntp.org to compute offset. When whisper queries time - this offset will be added/substracted from current time.

Query is executed every 2 mins, queries 5 different servers, cut offs min and max and the computes mean value. pool.ntp.org is resolved to different servers and according to documentation you will rarely hit the same.

Closes: #687
