Vim automatically adds a space between strings when concatenating them
without the dot operator. This is not obvious so we always use the dot
operator.
Minor coding style changes when writing statements on multiple lines to
be more consistent.

[READY] Fix exception when response future is not set
An `AttributeError` exception is raised when `Done` is called before `Start` in the `CompletionRequest` and `EventNotification` classes because the `_response_future` attribute is not yet defined.
Fixes#2461.

[READY] Catch and log all server exceptions
A lot of different errors may occur when sending a request to ycmd and receiving its response:
- [any exception from the requests module](http://docs.python-requests.org/en/master/_modules/requests/exceptions/);
- exceptions from ycmd: `ServerError` and `UnknownExtraConf`;
- `RuntimeError` exception from invalid HMAC;
- and possibly others.
Thanks to PR #2430, we can now catch and log these exceptions.
I am marking this PR as WIP because I'd like to add tests but I am not sure on how to implement them. Should we use actual code for these tests or mock the response from the ycmd server?
Fixes#2216.
Fixes#2272.

This is another attempt at:
https://github.com/Valloric/YouCompleteMe/pull/2473
Which removed the apparently flawed attempt at "lazy" loading of YCM.
While it fails to get the load out of the critical startup path, it
*does* serve the useful purpose when starting up gvim of avoiding a
deadlock situation in gvim.
So, this time, we keep VimEnter, but only for the gui-starting case. We
update the comment to explain what is actually happening. And we can
keep the docs about how to defer loading.
[READY] Do not use BufReadPre autocommand
This autocommand has a bug that makes the cursor goes to the first line of the current buffer when opening the preview window with `:pedit`. Since the `BufRead` autocommand is always called after, we can drop it by moving the `s:OnBufferReadPre` logic into the `s:OnBufferRead` function.
Fixes#2466.

As discussed in https://github.com/Valloric/YouCompleteMe/pull/2454,
this code doesn't do what it claims to do on the surface, so we should
delete it.
I'll follow up with a commit to explain in the README how to actually
defer loading of the plug-in.
[READY] Remove outdated Syntastic option
The `ycm_register_as_syntastic_checker` option was introduced a long time ago in commit 16b6f877c6 and became obsolete when [Syntastic support was replaced](6c01881e1a). Since then, it doesn't serve any purpose except being an alias to the `ycm_show_diagnostics_ui` option which can be an issue (see #2455) so we remove it.
Fixes#2455.

[READY] Add client logfile
We have a lot of issue reports with Python exceptions that interrupt user workflow or even worse make the editor unusable and force users to restart it (e.g. issue https://github.com/Valloric/YouCompleteMe/issues/2192). We really want to avoid that but at the same time we can't just silence these exceptions because they are useful to debug the issue. Logging them to Vim `:messages` is not practical because we can't write to it without displaying messages in the status line which, in addition to distract users, may lead to various issues like the infamous `Press ENTER or type command to continue` message. This is why a logfile is needed.
For now, only server crashes are logged but more logging will be added: connection issues with the server (`ConnectTimeout`, `ReadTimeout`, etc. exceptions), UltiSnips unavailability, requests sent to the server, etc.
The behavior of the `:YcmToggleLogs` command is changed to accept multiple arguments where each argument is a logfile name. Each of these files is opened in a separate window or closed if already open. When no argument is given, the list of available logfiles is displayed to the user. Example:
```
Available logfiles are:
ycm_pz83u7.log
ycmd_23830_stderr_gf6j3i.log
ycmd_23830_stdout_gmpa_k.log
```
With this change and PR #2342, we will add the completers logfiles to the list of files that can be opened with the `:YcmToggleLogs` command.
A bunch of tests are added that cover almost all changes introduced by this PR.

[READY] Fix flake8 error
This fixes a new error detected by the last version of `pycodestyle` (2.2.0), which is a dependency of `flake8`:

# Why this change is necessary and useful
[Please explain **in detail** why the changes in this PR are needed.]
See pull request: [#2072](https://github.com/Valloric/YouCompleteMe/pull/2072)
Unfortunately I was not able to reproduce the original author's results. I tried using a clean .vim and .vimrc. The only plugins I used were YCM and ctrlfs.vim, just as the original author mentioned. The .vimrc looks like this:
```VimL
syntax on
set history=500
set nocp
filetype plugin indent on
set encoding=GBK
```
Whatever I tried to do with configuration, I couldn't get a start without an error, but it is already known that YCM doesn't work properly with any file not using UTF encoding.
The error I was getting on vim start up:
```
Error detected while processing function youcompleteme#Enable[67]..<SNR>36_OnBufferRead[6]..<SNR>36_AllowedToCompleteInCurrentBuffer[1]..<SNR>36_AllowedToCompleteInBuffer:
line 15:

line 15:

Press ENTER or type command to continue
```
Error I was having after almost every key press:
```

# Why this change is necessary and useful
Auto-inserting namespace imports in C# is broken because the `ReplaceChunk()` call is missing an argument
[cont]: https://github.com/Valloric/YouCompleteMe/blob/master/CONTRIBUTING.md
[code]: https://github.com/Valloric/YouCompleteMe/blob/master/CODE_OF_CONDUCT.md
ReplaceChunk must have changed to require the buffer at some point
No test is included because it's a one-line change; the method is theoretically covered, so I'm not sure why the missing argument error was not caught (not familiar with these tests). Happy to add one if needed (and I can get pointed in the right direction).
