* context: fixed documentation to be more specific about ContextKeyConn being the key for a gossh.ServerConn

* Remote forwarding (#87)
* Update generateSigner key size to 2048 (#62)
Fixes#58
* Add syntax highlighting to readme (#67)
* small api updates (#69)
These updates make it easier to implement and pass custom Session and
Context implementations
No compatibilty breaking, all tests pass
* Move channelHandlers to avoid data race (#59)
* Update tests to work with go 1.10+ (#73)
Fixes#72
* Update shutdown to use a WaitGroup rather than sleeping (#74)
* Fix race condition in TestServerClose (#75)
In test server close, 3 things need to happen in order:
- Client session start
- Server.Close
- Client session exit (With io.EOF)
This fix ensures the client won't do anything until after the call to
close which ensure's we'll get io.EOF rather than a different error.
* Update circleci config to test multiple go versions
* Update CircleCI config to test 1.9 and the latest
The x/crypto/ssh library dropped support go < 1.9 as that's the first
version to have the math/bits library.

* Wait for connections to finish when shutting down
PR #74 introduced a WaitGroup for listeners, but it doesn't wait for
open connections before closing the server. This patch waits until all
conns are closed before returning from Shutdown.
* Support port forwarding of literal IPv6 addresses (#85)
* Support port forwarding of literal IPv6 addresses
To disambiguate between colons as host:port separators and as IPv6 address separators, literal IPv6 addresses use square brackets around the address (https://en.wikipedia.org/wiki/IPv6_address#Literal_IPv6_addresses_in_network_resource_identifiers). So host ::1, port 22 is written as [::1]:22, and therefore a simple concatenation of host, colon, and port doesn't work. Fortunately net.JoinHostPort already implements this functionality, so with a bit of type gymnastics we can generate dest in an IPv6-safe way.

* agent: added agent forwarding support with an example
* context: encode session id to hex string
* agent: ensure conn doesn't change in closure as loop iterates
* tests: use HostKeyCallback in ClientConfig
* README: noting examples in _example
* agent: documented exported names, added constants for temp file creation
