See merge request !2665

Generate valid (RFC 2111) Message-ID in email rejection mailer

Use a Message-ID that is RFC 2111 compliant. This fix is consistent with
how the Message-ID is generated in the 'notify' mailer.

Allow manual resize of js-autosize textareas

First, the autosize library was being too controlling and removed the
`resize` property from any elements to which it was attached, removing
the drag handle. We've disabled this behavior in the vendored library
and added a spec to prevent a regression during an upgrade.

Second, we detect (as best we can) when the user manually resizes an
autosize textarea, and then remove the autosize behavior from it and
increase its max-height.

This should allow for the best of both worlds.

Instead of running ClosingIssueExtractor for every commit in a merge
request we can gather all the commit messages (and the merge request
description), concatenate all this together and then run
ClosingIssueExtractor only once.

The result of this is that MergeRequest#closes_issues is now between
3.5x and 4x faster than the old setup. Using a merge request with 10
commits (each referencing a number of issues to close) this reduced the
call duration from around 200 milliseconds to around 50 milliseconds.

As a result of these changes the Jira related tests for
MergeRequest#closes_issues have been removed. These tests stubbed
Commit#closes_issues meaning that the only code that was really tested
was the call to Array#uniq to filter out duplicate issues. As this code
is no longer used (nor present) the corresponding tests were removed.

Increase LFS objects size column

Fixes #12745 

Increases the `size` column integer limit to an 8-byte integer. This allows for a max value of `9223372036854775807` which is 9,223,372,036 GB. That should do it 😃 

I tested this by first reproducing the error (push a file larger than 2.1 GB). The error was:

```
RangeError (3145728000 is out of range for ActiveRecord::ConnectionAdapters::PostgreSQL::OID::Integer with limit 4):
  lib/gitlab/lfs/response.rb:232:in `store_file'
  lib/gitlab/lfs/response.rb:170:in `render_lfs_upload_ok'
  lib/gitlab/lfs/response.rb:51:in `block in render_storage_upload_store_response'

  lib/gitlab/backend/grack_auth.rb:18:in `call_with_kerberos_support'
  lib/gitlab/backend/grack_auth.rb:8:in `call'
```

Then I ran this migration and pushed the file again. It uploaded successfully.
