In order to be able to ship protocol v2 with only supporting fetch, we
need clients to not issue a request to use protocol v2 when pushing
(since the client currently doesn't know how to push using protocol v2).
This allows a client to have protocol v2 configured in
`protocol.version` and take advantage of using v2 for fetch and falling
back to using v0 when pushing while v2 for push is being designed.
We could run into issues if we didn't fall back to protocol v2 when
pushing right now. This is because currently a server will ignore a request to
use v2 when contacting the 'receive-pack' endpoint and fall back to
using v0, but when push v2 is rolled out to servers, the 'receive-pack'
endpoint will start responding using v2. So we don't want to get into a
state where a client is requesting to push with v2 before they actually
know how to push using v2.

Teach remote-curl the 'stateless-connect' command which is used to
establish a stateless connection with servers which support protocol
version 2. This allows remote-curl to act as a proxy, allowing the git
client to communicate natively with a remote end, simply using
remote-curl as a pass through to convert requests to http.

When communicating with a v2 server, perform a fetch by requesting the
'fetch' command.

Construct an argv_array of ref prefixes based on the patterns supplied
via the command line and pass them to 'transport_get_remote_refs()' to
be used when communicating protocol v2 so that the server can limit the
ref advertisement based on those prefixes.

Teach the client to be able to request a remote's refs using protocol
v2. This is done by having a client issue a 'ls-refs' request to a v2
server.
