rafthttp has different requirements for connections created by the
transport for different usage, and this is hard to achieve when giving
one http.RoundTripper. Pass into pkg the data needed to build transport
now, and let rafthttp build its own transports.
I found some typos. Please let me know if you have any feedback.
Thanks,

time.AfterFunc() creates its own goroutine and calls the callback
function in the goroutine. It can cause datarace like the problem
fixed in the commit de1a16e0f107c4e1ffcc7128f7f343baf9631e30 . This
commit also fixes the potential dataraces of tests in
etcdserver/server_test.go .
We use url.ParseQuery to parse names-to-urls string, but it has side
effect that unescape the string. If the initial-cluster string has ipv6
which contains `%25`, it will unescape it to `%` and make further url
parse failed.
Fix it by modifiying the parse process.
Go1.4 doesn't support literal IPv6 address w/ zone in
URI(https://github.com/golang/go/issues/6530), so we only enable tests
in Go1.5+.
This fixes the problem that proposal cannot be applied.
When start the etcdserver.run loop, it expects to get the latest
existing snapshot. It should not attempt to request one because the loop
is the entity to create the snapshot.
1. I found a little typo (easily -> easy)
2. If you go to https://coreos.com/etcd/docs/2.0.9/proxy.html,
the proxy flag command is out of width of the web-page. Can
we have line-breaks between flags to make the command easier
to read?
Thanks for the great documentation!
One txn is treated as atomic, and might contain multiple Put/Delete/Range
operations. For now, between these operations, we might call forecCommit
to sync the change to disk, or backend may commit it in background.
Thus the snapshot state might contains an unfinished multiple objects
transaction, which is dangerous if database is restored from the snapshot.
This PR makes KV txn hold batchTx lock during the process and avoids
commit to happen.
When using Snapshot function, it is expected:
1. know the size of snapshot before writing data
2. split snapshot-ready phase and write-data phase. so we could cut
snapshot first and write data later.
Update its interface to fit the requirement of etcdserver.
Before this PR, it always prints nil because cluster info has not been
covered when print:
```
2015-10-02 14:00:24.353631 I | etcdserver: loaded cluster information
from store: <nil>
```
snapshotStore is the store of snapshot, and it supports to get latest snapshot
and save incoming snapshot.
raftStorage supports to get latest snapshot when v3demo is open.
