This is implemented so that the issues like in the
following flow don't affect the behavior of operation.
```
GetObjectInfo()
.... --> Time window for mutation (no lock held)
.... --> Time window for mutation (no lock held)
GetObject()
```
This happens when two simultaneous uploads are made
to the same object the object has returned wrong
info to the client.
Another classic example is "CopyObject" API itself
which reads from a source object and copies to
destination object.

This patch brings in changes from miniobrowser repo.
- Bucket policy UI and functionality fixes by @krishnasrinivas
- Bucket policy implementation by @balamurugana
- UI changes and new functionality changing password etc. @rushenn
- UI and new functionality for sharing URLs, deleting files
@rushenn and @krishnasrinivas.
- Other misc fixes by @vadmeste@brendanashworth
This change adds more richer error response
for JSON-RPC by interpreting object layer
errors to corresponding meaningful errors
for the web browser.
```go
&json2.Error{
Message: "Bucket Name Invalid, Only lowercase letters, full stops, and numbers are allowed.",
}
```
Additionally this patch also allows PresignedGetObject()
to take expiry parameter to have variable expiry.
* Return negative values of Total and Free in StorageInfo() when we fail to get disk info
* Return consistent messages in web handlers when the server is not initialized
This change initializes rpc servers associated with disks that are
local. It makes object layer initialization on demand, namely on the
first request to the object layer.
Also adds lock RPC service vendorized minio/dsync
This API is precursor before implementing `minio lambda` and `mc` continous replication.
This new api is an extention to BucketNofication APIs.
// Request
```
GET /bucket?notificationARN=arn:minio:lambda:us-east-1:10:minio HTTP/1.1
...
...
```
// Response
```
{"Records": ...}
...
...
...
{"Records": ...}
```
Object upload from browser should save additional
incoming metadata. Additionally should also notify
through bucket notifications once they are set.
Fixes#2292
Change brings in a new signVerifyReader which provides a io.Reader
compatible reader, additionally implements Verify() function.
Verify() function validates the signature present in the incoming
request. This approach is choosen to avoid complexities involved
in using io.Pipe().
Thanks to Krishna for his inputs on this.

This is necessary for calculating the total storage
capacity from object layer. This value is also needed for
browser UI.
Buckets used to carry this information, this patch
deprecates this feature.
It is the bucket and volumes which needs to have this
value rather than the DiskInfo API itself. Eventually
this can be extended to show disk usage per
Buckets/Volumes whenever we have that functionality.
For now since buckets/volumes are thinly provisioned
this is the right approach.
