Users importing from Bitbucket Cloud, Bitbucket Server, or GitHub
often complained about getting failed imports due to 422 errors.
This change ensures that project names are imported with names that
are guaranteed to pass the regular expression validation.

Fix wrong commit count in push event payload

Closes #49971

See merge request gitlab-org/gitlab-ce!21338

Due to a regression in !20608, the LDAP authenticator was not being used
unless OmniAuth was enabled. This change allows the LDAP provider to be used
if it is configured regardless of the OmniAuth setting.

Closes #50579

This fixes a regression in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20916.
We now only use the full commit count for the initial push to the default branch.
Otherwise, we rely on the number of commits that we calculated occurred in the push.

The original behavior in 11.1.4:

1. When a new branch is pushed, `@push_commits_count` was set to the total
number of refs available for the branch.
2. For other branches, `@push_commits_count` would remain `nil`.
3. `GitPushService#build_push_data` would build the push data with
`@push_commits_count`.
4. If this were `nil`, it would be set to the right value here:
https://gitlab.com/gitlab-org/gitlab-ce/blob/v11.1.4/lib/gitlab/data_builder/push.rb#L60

Broken behavior:

1. `GitPushService#push_commits_count` is always called.
2. The total number of commits is therefore always equal to the total number of refs available.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/49971

Improve system hook spec in spec/services/git_push_service_spec.rb

See merge request gitlab-org/gitlab-ce!21347

Update gitlab-svgs to 1.2.8

See merge request gitlab-org/gitlab-ce!21346

When a diff has a significant number of commits, the previous behavior would
attempt to render the Markdown on all the commit messages but only display
1000 of them. To avoid additional work, we only need to render the Markdown
on the set that is displayed.

See https://github.com/fog/fog-google/pull/409.

Relates to https://gitlab.com/gitlab-org/gitlab-ce/issues/49957

Previously `SystemHookPushWorker` would always be called after a push event,
and this would queue a Sidekiq job regardless of whether any system hooks
needed that event. Moreover, another call inside `Project#execute_hooks` would
also fire system hooks if they existed.

This change both removes the duplicate system hook calls. For installations
without system hooks for push events, this change also can save significant
amount of RAM used by Redis.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/50549
