Consider the scenario:

1. The default visibility level is set to internal
2. A user attempts to create a private project within a private group

Previously this would always fail because default_value_for would
overwrite the private visibility setting, no matter what
visibility_level were specified. This was happening because
default_value_for was confused by the default value of 0 specified by
the database schema.

default_value_for attempts to assign the default value in the block by
checking whether the attribute has changed. The problem is that since
the default value by the database was 0, and the user requested 0, this
appeared as though no changes were made. As a result, default_value_for
would always overwrite the user's preference.

To fix this, we remove the use of default_value_for and only set the
visibility level to the default application setting when no preference
has been given at creation time.

In production, we've seen the rendering times of the merge request
widget increase as a result of loading commit data. BatchLoader attempts
to call replace_methods on the lazy object, but this has a significant
performance penalty for modules that have many methods. Disabling this
mode (https://github.com/exAspArk/batch-loader/pull/45) appears to cut
load times by about 50% for MergeRequestsController#show.

Process up to 100 commit messages for references when pushing to a new default branch

See merge request gitlab-org/gitlab-ce!29511

Commit messages are not processed for references to issues when
creating the default branch on push. This was expected
behavior (probably to avoid performance problems when first pushing a
repository with thousands of commits). However, this is not an issue
because we always limit the number of commits to process to 100
regardless of whether we are creating the default branch or not.
