Check that uploaded file content matches the file extension

See merge request gitlab-org/gitlab!20697

Handle when extension is missing
Handle ambiguous file type checks
- Content of text files often don't define their type.
- A text file may be missing a file extension.
- We may encounter a file with no extension that we can't magically
type.
Optionally check integrity of specific mime types
Ensure upload integrity by file extension
Apply integrity check to AvatarUploader and FaviconUploader

Drop redundant index on ci_pipelines.project_id

See merge request gitlab-org/gitlab!22325

When an issue, MR, or epic contains a lot of user references (even to
the same user), we use the method
Banzai::ReferenceParser::BaseParser.collection_objects_for_ids to load
those users and maintain the loaded users for the current request in a
RequestStore cache.

This method calls Hash#values_at with the splatted IDs - so one argument
per ID passed in. If enough IDs are passed in, it's possible for the
arguments here to overflow the stack.

Let's say we have:

    ids = [1] * 1_000_000; ids.length
    #=> 1000000
    cache = {}
    #=> {}
    cache.values_at(*ids).compact
    # SystemStackError: stack level too deep

We could do this `cache.values_at(*ids.uniq).compact`, but that would
fail in this case:

    distinct_ids = 1.upto(1_000_000).to_a; distinct_ids.length
    #=> 1000000
    cache.values_at(*distinct_ids.uniq).compact
    # SystemStackError: stack level too deep

So the best option seems to be to just write a slower, but
non-stack-consuming, version:

    Benchmark.realtime { ids.uniq.map { |id| cache[id] }.compact }
    #=> 0.15192799968644977
    Benchmark.realtime { distinct_ids.uniq.map { |id| cache[id] }.compact }
    #=> 0.3621319998055696

To test this locally, you can replace the last issue's description with
a lot of mentions of a user (here I've created a user with the username
't'), but it takes a long time:

    problem = ('@t ' * 1_000_000)[0...1_000_000]; problem.length
    #=> 1000000
    Issue.last.update!(description: problem_string)

Visiting that issue in the UI will then overflow the stack. With this
change, it won't (although it is very slow).
