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.

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.
Second, we detect 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.
Closes#12832
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.

Background process note logic for #3948
Quick and dirty way to get *most* of the note processing out of band and into the background. Seeing some pretty nice speed bumps. Keep in mind that doing this in process results in slower and slower responses as more notes are added and more participants exist.
```
without background processing
Completed 200 OK in 627ms (Views: 0.5ms | ActiveRecord: 32.3ms)
Completed 200 OK in 478ms (Views: 0.8ms | ActiveRecord: 28.3ms)
Completed 200 OK in 1107ms (Views: 0.6ms | ActiveRecord: 36.6ms)
with background processing
Completed 200 OK in 108ms (Views: 0.6ms | ActiveRecord: 4.7ms)
Completed 200 OK in 78ms (Views: 0.5ms | ActiveRecord: 4.5ms)
Completed 200 OK in 164ms (Views: 0.5ms | ActiveRecord: 8.3ms)
```
As you can see, speeds are consistent when doing the harder work out of process. I'm not sure the number of sql queries we're saving, but based on the logs alone it's a pretty good amount.
@dzaporozhets @yorickpeterse I would love some input on this.

fix syntax error on 2.1 and rubocop on 2.2
Background:
Hashes `{:'key': 'value'}` are not valid in 2.1 but are recommended by Rubocop on 2.2. We only use those when we have a key such as `weird-key`, `weird.key`, etc...
We could disable Rubocop but it wouldn't warn us about the recommended syntax since `Ruby 1.9`: `{key: 'value'}`, which is valid for `Ruby 1.9+`.
Workaround 1 could be disabling `Style/HashSyntax:` in `rubocop.yml`.
Workaround 2 (tried in this MR) is to trick Rubocop using `.to_sym` which is effectively the same as adding the `:`. This would allow to keep the warning in place.
