If a handshake was already in progress, messages were dropped.
Instead of this, it is better to queue these and send as soon
as the handshake is finished and thus the encryption key is known.

Sessions were limited to 256 for some reason.
For large scale operation it makes sense to allow more
open sessions (symmetric key sessions).

We do not need that many responses with FindNodeFast, since the
reposes can be ordered by distance

We really don't need this to be 4 seconds.
Later we should tune it better based on measurements

This is needed in cases where the response arrives before
moving to the next instruction, such as a directly connected
test.

* track nim-libp2p's unstable branch and nim-bearssl's master branch
refactor accordingly: mainly switching from `import bearssl` to
`import bearssl/rand`, `BrHmacDrbgContext` to `HmacDrbgContext`, and related
changes
* fix ambiguous identifier
* nim 1.4 is deprecated

* initial providers manager implementation
* misc license update
* spelling
* rename provider tests
* add provider tests
* reexport provider manager
* only update provider record if it changed
* small bug in getProvByKey
* pass providers to both constructors
* fix records retrieval
* disable cache during tests
* avoid redefining data
* adding back tests with cache
* use `.errorOption`
* proper err msg unpacking
Closes: #2.
Libp2p supports multiple cryptographic curves, however we have currently only implented support for secp256k1.
This needs to be run with the compiler flag `libp2p_pki_schemes` set to `secp256k1`. If running the tests, this can be run like so: `nimble test —libp2p_pki_schemes=secp256k1` to put secp as the first supported crypto scheme.
This patch adds a findNode message sending the actual
target ID as in traditional Kademlia lookup. This in
contrast to the actual findNode message that send information
about the distance only, leading to more secure but slower lookups.
Having both primitives allows us to select which to use per use case.
Current naming is findNode for the distance based message and
findNodeFast for the message added in this patch.
Previous version was very conservative about adding nodes to the
routing table, requiring a full request/response message exchange
initiated by us.
Here we also add the node as 'seen' if the whoareyou/handshake
exchange was successful.
This significantly speeds up bootstreap from 0
