Henry de Valence 7d0a3debb6 chain: ensure impl Deserialize for Amount validates data. 
This uses serde's try_from attribute to run deserialized values through the
TryFrom impl.  Also adds a test to make sure that validation actually does
happen.

Henry de Valence b59cfc49b7 sync: create requests sequentially to respect backpressure. 
This seems like a better design on principle but also appears to give a much
nicer sawtooth pattern of queued blocks in the checkpointer and a much smoother
pattern of block requests.

Henry de Valence 4aa00ad216 Align crate versions and user-agent with NU numbers. 
We had a brief discussion on discord and it seemed like we had consensus on the
following versioning policy:

* zebrad: match major version to NU version, so we will start by releasing
  zebrad 3.0.0;

* zebra-* libraries: start by matching zebrad's version, then increment major
  versions of each library as we need to make breaking changes (potentially
  faster than the zebrad version, always respecting semver but making no
  guarantees about the longevity of major releases).

This commit sets all of the crate versions to 3.0.0-alpha.0 -- the -alpha.0
marks it as a prerelease not subject to perfect adherence to compatibility
guarantees.

Henry de Valence 49aa41544d sync: try to ignore spurious inv messages. 
Closes #697.

per  https://github.com/ZcashFoundation/zebra/issues/697#issuecomment-662742971

The response to a getblocks message is an inv message with the hashes of the
following blocks. However, inv messages are also sent unsolicited to gossip new
blocks across the network. Normally, this wouldn't be a problem, because for
every other request we filter only for the messages that are relevant to us.
But because the response to a getblocks message is an inv, the network layer
doesn't (and can't) distinguish between the response inv and the unsolicited
inv.

But there is a mitigation we can do. In our sync algorithm we have two phases:
(1) "ObtainTips" to get a set of tips to chase down, (2) repeatedly call
"ExtendTips" to extend those as far as possible. The unsolicited inv messages
have length 1, but when extending tips we expect to get more than one hash. So
we could reject responses in ExtendTips that have length 1 in order to ignore
these messages. This way we automatically ignore gossip messages during initial
block sync (while we're extending a tip) but we don't ignore length-1 responses
while trying to obtain tips (while querying the network for new tips).
