Go 1.13 was accidently added, this backs it back out.
I don't think there's really much impact from this but I would prefer it
not be in there for this release.
* Fix#406: reconnect() can be called while still connected
* Add memberMap to speed up member queries
* Fix error return value and remove deletion
* Fix GuildAdd member map initialization edge case
* Add rate limit buffering support
- Break request into requestInner
- Break LockBucket into LockBucketObject
- Change getBucket to GetBucket so it can be externally accessed
- Add RequestBuffer interface
- Add RequestBuffer pointer to Bucket struct
- Add RequestPostWithBuffer() function to Session
* Remove internal implementation, export ratelimiter instead
* Add heartbeat ACK response and error handling
- Error when sending a heartbeat now triggers a reconnection
- Op7 now triggers a reconnection
- Session now tracks the last heartbeat ACK that was recieved. If the
last ACK is more than FailedHeartbeatAcks*heartbeatinterval in the past,
this is treated as a dead connection and a reconnection is forced.
* Address @iopred comments
* Added ratelimiter
Handles the new ratelimit headers
- X-RateLimit-Remaining
- X-RateLimit-Reset
- X-RateLimit-Global
* Pad only reset time with a second
* Moved ratelimiter out of internal package
* Change for loop, move global ratelimit check inside sleep check
* Moved ratelimiter locking to getBucket
* Added global bucket
* Changed how bucket id's are done
Now each request function will need to specify the bucket id if the
endpoint contains minor variables
* Allow empty bucketID in request
* Remove some uneeded Endpoint* function calls
* Added test for global ratelimits
* Fixed a silly little mistake causing incorrect ratelimits
* Update test comments, Fixed treating a endpoint as 2 in ratelimiting
* Use date header from discord instead of relying on sys time sync
* Update all REST functions to use RequestWithBucketID
* Embed mutex into bucket
* Added webhook and reaction buckets
Also cleaned up identify sending so there's now a function that handles
it instead of duplicate code. Renamed handshake* structs to identify*
structs to make naming match up.
We now store teh sessionID of the gateway connection for later use. We
are now caching the gateway url and will use it until unable to connect
to that gateway. We're not longer smashing the VoiceConnections map
during reconnects which was causing Voice problems. Slight change to
log output format.
