[READY] Move client tests to the main tests folder
This makes it possible to configure all tests at a package level by implementing the `setUpPackage` and `tearDownPackage` functions in `python/ycm/tests/__init__.py` file.

# Why this change is necessary and useful
See issue #2021. This is a partial implementation based on the syntastic option referenced, supporting the `!` flag and filters of type `regex` and `level`. Also supports filetype specific filters using `ycm_<ft>_quiet_messages`, but I couldn't think of a great way to fall back to syntastic configs for this one.
In terms of usefulness: I've been playing with C# recently, which has a bunch of style warnings that I don't want to follow, and prefer to only have the gutter showing if there are actually errors, or warnings that I *do* want to follow.

We eagerly compile all the filters up front, then gather the
compiled filters into a DiagnosticFilter lazily, caching the
result to avoid garbage lists.
[READY] Move test_utils.py file to tests folder
We don't want `test_utils.py` to appear in the coverage reports. Instead of blacklisting it in `.coveragerc`, we move it to the tests folder.
This will decrease coverage.

[READY] Refactor tests using a YouCompleteMe instance
This PR adds a decorator function, similar to the `IsolatedYcmd` and `SharedYcmd` decorators from ycmd, that passes a YouCompleteMe object to tests. Its options can be customized with the parameter of the decorator. I need this to write new tests.
There is one thing annoying with this change is that Vim does not highlight a decorator function with no character between the parentheses so `@YouCompleteMeInstance()` will not be highlighted. I've contacted the maintainer of the Python syntax file about this bug. Anyway, that's not a good reason to not make this change.

[READY] Add coverage support
There should not have anything to configure on codecov website.
I updated the `run_tests` script to behave exactly like the one in ycmd repository: when passing tests as arguments, you need to specify the path from the root project, not the `python` folder. For instance:
```
./run_tests.py --skip-build -- python/ycm/tests/event_notification_test.py
```
instead of
```
./run_tests.py --skip-build -- ycm/tests/event_notification_test.py
```
This way, you can now complete the path to the test.

[READY] Use deleted buffer instead of current buffer when sending BufferUnload event notification
When deleting a buffer, we use the current buffer to send the `BufferUnload` event notification request to ycmd instead of the buffer being deleted. This is an issue when the current buffer is not of the same filetype as the deleted one. In this case, three different scenarios may occur:
- the current buffer filetype is not allowed: no request is sent to the ycmd server. The `OnBufferUnload` method from the completer corresponding to the filetype of the deleted buffer is not called. If the filetype is a C-family language, the translation unit is not destroyed. If it is TypeScript, we don't tell TSServer to close the file (not really an issue unless the file is modified elsewhere);
- the current buffer filetype has no semantic support in ycmd: the request is sent to the ycmd server but no semantic completer is used. Same result;
- the current buffer filetype has semantic support in ycmd: the `OnBufferUnload` method from the wrong completer is called in ycmd. LibClang and TSServer are able to cope with that and ignore the file. Same result in definitive.
The solution is obvious: build the request for the deleted buffer in this case. However, this involves more changes than expected because the code was written with the assumption that requests are always for the current buffer.
The `include_buffer_data` parameter from `BuildRequestData` was removed as it is always used with its default value.
This fix may alleviate issue https://github.com/Valloric/YouCompleteMe/issues/2232 in the sense that it now gives a reliable way to limit memory usage by deleting buffers in the case of multiple TUs.
Next step is to update PR https://github.com/Valloric/ycmd/pull/542 by removing the `unloaded_buffer` parameter from ycmd API then remove it from the `BufferUnload` request in YCM.

Send the request as the unloaded buffer instead of the current buffer
for the BufferUnload event notification. This fixes the issue where
the filetype of the current buffer is not the same as the unloaded
buffer one, making the ycmd server uses the wrong completer when
handling the request.
Use JoinLinesAsUnicode in GetUnsavedAndCurrentBufferData().

# Why this change is necessary and useful
GetUnsavedAndCurrentBufferData() is invoked on every kepress. On a large file (15+k loc), using this new function takes kepress latency down to <10ms from ~100ms.
The function used here is added to ycmd in https://github.com/Valloric/ycmd/pull/617. I will update this PR to include a ycmd submodule update if and when that PR is merged.

# Why this change is necessary and useful
Updates ycmd submodule to latest (see below), and updates the subcommand documentation to cover `GetDocImprecise` and the new `GetTypeImprecise`.
Other user-visible changes being included (Release notes):
- PR 590: Enable KeepGoing option when creating translation units in Clang completer
- PR 595: Fix default include paths for macOS Sierra
- PR 596: Fix javascript subcommand errors for relative paths.
- Fix for #607
- PR 609: Support GetTypeQuick completer subcommand in clang completer
- PR 615: Rename GetDocQuick subcommand to GetDocImprecise
Text in the subcommand documentation is deliberately almost identical to `GoToImprecise`

[READY] Bumps required Vim to 7.4.143 and adopts TextChangedI.
Long and personal experience, when TextChangedI gets used, YCM seems
to perform better, diagnostics will trigger much less frequently at
inappropriate occasions, even less with whitespace agnostic triggers,
if I recall correctly...
There's a previous discussion at #1337. At the time this change was bundled in
a single pull request with other changes.
It has gone through the test of the time, sole issue I've stumbled upon was reported
by @puremourning at https://github.com/oblitum/YouCompleteMe/issues/10. This
is what me and other users of my fork use daily.
