Optimize LDAP and add a search timeout
Related to #4282
This merge request arranges some things in `access.rb` to facilitate some optimizations in EE (to come later). It also adds a 10 second timeout to all LDAP searches so the entire worker is not blocked if some query doesn't return in a reasonable amount of time. This timeout is configurable per LDAP server.

Do not call API if there is no API URL
Fixes#5878
CE users may not be interested in the new JIRA features. In this case,
we should detect they haven't set an API URL and fallback to the
behavior pre-8.3. This patch does that very easily.
There are planned improvements to JIRA in future releases such as
gitlab-org/gitlab-ce#5541 which will make this more configurable.

Suppress e-mails on failed builds if allow_failure is set
Every time I push to GitLab, I get > 2 emails saying a spec failed when I don't care about the benchmarks and others that have `allow_failure` set to `true`.
@ayufan mentioned creating a summary e-mail to prevent getting one e-mail per build, but the latter might actually be desirable. For example, I do want to know if Rubocop errors fail right away.

Get "Merge when build succeeds" to work when commits were pushed to MR
target branch while builds were running
The Merge when build succeeds service only merges when the MR is
mergeable (open, not WIP, no conflicts).
When the target branch is updated, all affected MRs have their merge
status set to `unchecked`, and the conflicts check will only happen
when `check_if_can_be_merged` is called, which happens when the MR page
is viewed.
When someone enables the automatic merge, the target branch is updated,
no-one views the MR page again, and the build succeeds, the mergeability
check will fail and the MR will not in fact be merged.
This MR makes sure `check_if_can_be_merged` is always called when MR
mergeability is checked.

Fix project transfer e-mail sending incorrect paths in e-mail notification
The introduction of ActiveJob and `deliver_now` in 7f214cee7 caused a race
condition where the mailer would be invoked before the project was committed
to the database, causing the transfer e-mail notification to show the old
path instead of the new one.
Closes#4670

Disable --follow in `git log` to avoid loading duplicate commit data in infinite scroll
`git` doesn't work properly when `--follow` and `--skip` are specified together. We could even be **omitting commits in the Web log** as a result.
Here are the gory details. Let's say you ran:
```
git log -n=5 --skip=2 README
```
This is the working case since it omits `--follow`. This is what happens:
1. `git` starts at `HEAD` and traverses down the tree until it finds the top-most commit relevant to README.
2. Once this is found, this commit is returned via `get_revision_1()`.
3. If the `skip_count` is positive, decrement and repeat step 2. Otherwise go onto step 4.
4. `show_log()` gets called with that commit.
5. Repeat step 1 until we have all five entries.
That's exactly what we want. What happens when you use `--follow`? You have to understand how step 1 is performed:
* When you specify a pathspec on the command-line (e.g. README), a flag `prune` [gets set here](https://github.com/git/git/blob/master/revision.c#L2351).
* If the `prune` flag is active, `get_commit_action()` determines whether the commit should be [scanned for matching paths](https://github.com/git/git/blob/master/revision.c#L2989).
* In the case of `--follow`, however, `prune` is [disabled here](https://github.com/git/git/blob/master/revision.c#L2350).
* As a result, a commit is never scanned for matching paths and therefore never pruned. `HEAD` will always get returned as the first commit, even if it's not relevant to the README.
* Making matters worse, the `--skip` in the example above would actually skip a every other entry after `HEAD` N times. If README were changed in these skipped commits, we would actually miss information!
Since git uses a matching algorithm to determine whether a file was renamed, I
believe `git` needs to generate a diff of each commit to do this and traverse
each commit one-by-one to do this. I think that's the rationale for disabling
the `prune` functionality since you can't just do a simple string comparison.

Fix identity and user retrieval when special characters are used
Fixes#4023
I also added tests to make sure the user with special characters in his name is returned correctly.
@rspeicher this probably should be added to 8.3 as a patch.
