Limit push email diff size

Restrict the size of diffs in push emails to 30 lines / 150 KB (whichever is smaller),
following https://gitlab.com/gitlab-org/gitlab_git/merge_requests/85.

Emails on push can get very large if they contain a lot of files that sneak under the single-file limit.

Fix RangeError exceptions when referring to issues or merge requests outside of max database values

When using #XYZ in Markdown text, if XYZ exceeds the maximum value of a signed 32-bit integer, we get an exception when the Markdown render attempts to run `where(iids: XYZ)`. Introduce a method that will throw out out-of-bounds values.

Add merge request data to the progress information on Milestones pages.

## What does this MR do?

Adds data about merge requests to the Milestone show view. It previously only showed something like `3 issues: 2 open and 1 closed 20% complete`, now it shows `3 issues: 2 open and 1 closed 2 merge requests: 2 open and 0 merged 20% complete`.
