Adds an emulation of Vim buffer object and moves change tracking into python.
Now diagnostics are stored per buffer, which effectively solves #2165 .

coverage.py 4.4 removed the path from the filename attribute in its reports.
This leads to incorrect coverage from codecov as it relies on this attribute to
find the source file. Require coverage.py older than version 4.4.

[READY] Clean C# inserting namespace code
Now that we require at least Vim 7.4.1578, we can remove the code that automatically insert namespaces in C# for Vim versions prior to 7.4.774.

[READY] Display diagnostics and parse initial buffer asynchronously using timers
Currently, we wait for an autocommand to trigger to display diagnostics. This is not ideal as users have to do some actions like moving the cursor or editing the buffer to see them. We can improve that by using [the timers feature introduced in Vim 7.4.1578](975b5271ee) to display diagnostics asynchronously. Here's a demo:
By displaying diagnostics asynchronously, we can drop the `CursorHold` and `CursorHoldI` autocommands as well as [the `g:ycm_allow_changing_updatetime` option](5a806dcb30/README.md (the-gycm_allow_changing_updatetime-option)). In addition, we can now parse the current buffer and display diagnostics on the `TextChanged` event instead of the `CursorMoved` one. Note that we still need to check `b:changed_tick` for the `InsertLeave` event.
Given that our policy is to support the latest version of Ubuntu LTS which is 16.04, and that version [bundles Vim 7.4.1689](http://packages.ubuntu.com/xenial/vim), we can increase our Vim version requirement to 7.4.1578.
Next steps will be to use timers for parsing the buffer when the server becomes ready and for completions.
Fixes https://github.com/Valloric/YouCompleteMe/issues/2165.

Use the timers feature to display diagnostics asynchronously instead of waiting
for an autocommand to trigger.
Increase Vim version requirement to 7.4.1578.
Drop the CursorHold and CursorHoldI autocommands.
Parse buffer on the TextChanged autocommand instead of CursorMoved.
[READY] Improve reparse requirement on BufEnter event
When opening a file, Vim triggers the `BufRead` event then the `BufEnter` one. By setting the `s:previous_allowed_buffer_number` variable in `s:AllowedToCompleteInBuffer`, we avoid a reparse on `BufEnter` after parsing the buffer on `BufRead`. This reduces the number of `BufferVisit` and `FileReadyToParse` requests sent to the server by one when opening a file.

[READY] Drop BufRead event
Since [we don't parse the buffer if no filetype is set](ad00f4c3f4/autoload/youcompleteme.vim (L334)), calling `s:OnBufferRead` on the `BufRead` event is only useful if the buffer filetype is set. But if that's the case, this means that the `FileType` event was fired before the `BufRead` one and thus the `s:OnBufferRead` function is already called. So, there is no point in calling `s:OnBufferRead` on the `BufRead` event. In fact, this costs us a `BufferVisit` and a `FileReadyToParse` request for nothing.

Considering that a buffer won't be parsed if no filetype is set and that it's
already parsed if the filetype is set when reading a buffer, there is no point
in parsing a buffer on the BufRead event.
[READY] Update autocommands examples in documentation
I am not aware of a Vim option to not switch to the location list (or quickfix) window when calling `lopen` (respectively `copen`) so I think it's a good idea to give an example in the docs on how to achieve this using the `YcmLocationOpened` and `YcmQuickFixOpened` autocommands.
Also, the `execute` calls are not needed.

[READY] Force parsing on buffer visit
When visiting a buffer that was previously parsed, its last parse may be outdated because of changes from other buffers. We need to force a new parse.
This partially fixes issue https://github.com/Valloric/YouCompleteMe/issues/2165 in the sense that you don't have to edit the buffer (or call `:YcmForceCompileAndDiagnostics`) anymore to refresh diagnostics but you still have to wait for the `CursorHold` event. This can be further improved by displaying diagnostics asynchronously using timers.

[READY] Refactor b:ycm_changedtick variable
Since we only use the `b:ycm_changedtick` variable to track the last time we parsed the buffer, we can change it to store a number instead of a dictionary.

[READY] Fix diagnostic highlighting with invalid location extent
ycmd may return a location extent with a starting column of zero (see the test for an example) which is not a valid column (columns are 1-indexed). We should use the location in this case. Also, when the location extent is not valid, we should call `AddDiagnosticSyntaxMatch` with the `is_error` parameter to highlight warnings as such and not as errors (`is_error` is `True` by default).

[READY] Do not cache Python interpreter path
Once YCM is installed through a plugin manager in Vim (e.g. using the `:PluginInstall` command with Vundle), it picks a Python interpreter (most likely the one used to run YCM inside Vim), caches it, and starts the server with it. This fails since the `ycm_core` library is not yet compiled and the following message is displayed on the status line:
```
The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). YCM core library not detected; you need to compile YCM before using it. Follow the instructions in the documentation.
```
After reading the documentation, the user may then build the library directly from Vim:
```
:!/path/to/YCM/install.py
```
or by opening a new terminal and calling the `install.py` script without leaving Vim. Once the compilation is done, he will restart the server with the `:YcmRestartServer` command. However, since the Python interpreter used to start the server is already cached, YCM will not pick the one from the `PYTHON_USED_DURING_BUILDING` file generated by the `install.py` script. If these Pythons are different (e.g. Python 2 versus Python 3), YCM will fail to start the server again. This doesn't happen if we don't cache the Python interpreter path.
I suspect this is the issue experienced in #2431 and often reported by users on Ubuntu 16.04 where Vim is compiled with Python 3 support but default Python is Python 2. See https://github.com/Valloric/YouCompleteMe/pull/2140#issuecomment-273495342 and https://github.com/Valloric/YouCompleteMe/issues/35#issuecomment-290877053.
Fixes#2431.
