8516d8ccc5 backend: force initial mmap size to 0 for windows 
boltdb on windows allocates a file with the full mmap size even if the
db is empty. Force the initial mmap size to 0 so there's no huge initial
db file on windows.

Fixes #7910

Meant to debug #6464 and #6934

Dumps the output from the etcd/etcdctl servers and SIGQUITs to get a
golang backtrace in case of a hanged process.

f6cd4d4f5b snap, etcdserver: tighten up snapshot path handling 
Computing the snapshot file path is error prone; snapshot recovery was
constructing file paths missing a path separator so the snapshot
would never be loaded. Instead, refactor the backend path handling
to use helper functions where possible.

etcdserver: renaming db happens after snapshot persists to wal and snap files

87d99fe038 etcd-runner: remove mutex on validate() and release() in global.go 
election runner can deadlock in atomic release().

suppose election runner has two clients A and B.
if A is a leader and B is a follower, B obtains lock
for release() and waits for A to close(nextc) which signal
next round is ready. However, A can only close(nextc) if it
obtains lock for release(); hence deadlock.

this pr removes atomicity of validate() and release() in global.go
and gives the responsibility of locking to each runner.

8b7b7222dd etcdserver: renaming db happens after snapshot persists to wal and snap files 
In the case that follower recieves a snapshot from leader
and crashes before renaming xxx.snap.db to db but after
snapshot has persisted to .wal and .snap, restarting
follower results loading old db, new .wal, and new .snap.
This will causes a index mismatch between snap metadata index
and consistent index from db.

This pr forces an ordering where saving/renaming db must
happen after snapshot is persisted to wal and snap file.
this guarantees wal and snap files are newer than db.
on server restart, etcd server checks if snap index > db consistent index.
if yes, etcd server attempts to load xxx.snap.db where xxx=snap index
if there is any and panic other wise.

Trying to decouple the v2 client from SRV code. Can't move
into discovery/ since that creates a circular dependency. So,
give up and move all the SRV code into a new package.
