[READY] Fix error when filetype is a number
When the filetype is set to a number (e.g. `set filetype=42`), YCM raises the following error:
```python
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\\Users\\micbou\\projects\\YouCompleteMe\\autoload\..\python\ycm\youcompleteme.py", line 571, in HandleFileParseRequest
self.NativeFiletypeCompletionUsable() ):
File "C:\\Users\\micbou\\projects\\YouCompleteMe\\autoload\..\python\ycm\youcompleteme.py", line 362, in NativeFiletypeCompletionUsable
return ( self.CurrentFiletypeCompletionEnabled() and
File "C:\\Users\\micbou\\projects\\YouCompleteMe\\autoload\..\python\ycm\youcompleteme.py", line 674, in CurrentFiletypeCompletionEnabled
filetypes = vimsupport.CurrentFiletypes()
File "C:\\Users\\micbou\\projects\\YouCompleteMe\\autoload\..\python\ycm\vimsupport.py", line 592, in CurrentFiletypes
return VimExpressionToPythonType( "&filetype" ).split( '.' )
AttributeError: 'int' object has no attribute 'split'
```
This happens because `VimExpressionToPythonType` automatically converts a string representing a number to an integer and an integer cannot be split.
Closes https://github.com/Valloric/YouCompleteMe/pull/2762.

[READY] Only call completion function if needed
Currently, YCM calls the `completefunc` at each key press even if there are no candidates. This has the side effect of always keeping the user in completion mode while typing in insert mode, which causes the following issues:
- the `<C-U>`, `<C-N>`, `<C-P>`, and `<C-E>` keys are not working as expected in insert mode when the completion menu is not visible;
- automatic comment formatting is broken in some situations. See issue https://github.com/Valloric/YouCompleteMe/issues/2552.
This is solved by only calling the `completefunc` if suggestions are available (or if the start column is not after the current column) and by closing the completion menu otherwise.
Updates the `<C-U>` entry in the FAQ.
Fixes https://github.com/Valloric/YouCompleteMe/issues/2552.

The VimExpressionToPythonType function automatically convert a number
represented as a string to an integer. This causes an error when used to
evaluate a filetype set to a number as the result is split on the dot character
to get a list of filetypes and an integer cannot be split. Use vim.eval and
ToUnicode instead.
[READY] Change GetBufferNumberForFilename default behavior
While I was looking at PR https://github.com/Valloric/YouCompleteMe/pull/2827, I noticed that the default behavior of `GetBufferNumberForFilename` is to create a buffer for the given filename if no buffer already exists for that filename. This behavior is rather unexpected given the name of that function. In fact, `GetBufferNumberForFilename` is almost always called with the `open_file_if_needed` parameter (renamed `create_buffer_if_needed` for clarity) sets to `False`. This really suggests that the default value should be `False` instead of `True`.
In addition, that default behavior may lead to performance issues when the server returns diagnostics for a lot of files with no corresponding buffers since this will create a buffer for each one of these files.

If no buffer exists for a given filename, the GetBufferNumberForFilename
function will create a buffer for that file by default. This behavior is
unexpected given the name of that function and may lead to performance issues
when ycmd returns diagnostics for a lot of files with no corresponding buffers.
The default behavior for that function should be to not create a buffer.
Do not call user's completion function if the start column is after the current
column or if there are no candidates. This avoids keeping the user in
completion mode even if there is no completion menu.
Include the following changes:
- automatically find Rust sources through rustup;
- do not return canonical type if identical to type in C-family languages;
- improve support of system Boost and system libclang on Gentoo;
- improve Red Hat and CentOS detection;
- consider header file entries in compilation database;
- improve completion of include statements in C-family languages;
- rename completer options in installation script;
- only include one macOS toolchain.
[READY] Improve server crash notification at startup
Instead of notifying the user if the server crashed immediately after starting it (which is unlikely to work because the server process is necessarily up at this point), do it during polling.

# Why this change is necessary and useful
This is a non-code PR adding instructions to the README.md file for situations where `cmake` may be the issue. The instructions simply specify that under certain scenarios, using `cmake3` instead of `cmake` may address the compilation-issues of YCM (eg. on older systems like Ubuntu 14.04). A reference to this issue can be found under the discussion here: [link](https://github.com/Valloric/YouCompleteMe/issues/2729#issuecomment-332961003)

On Windows, the options file cannot be deleted while it is still open by
another process. Close the file before starting the server. Do not explicitly
flush the file as closing implies flushing.
[READY] Improve path to python interpreter error handling
YCM returns the cryptic error `YouCompleteMe unavailable: [Errno 2] No such file or directory` when the Python interpreter path used to start the server doesn't exist. See issues https://github.com/Valloric/YouCompleteMe/issues/2773 and https://github.com/Valloric/YouCompleteMe/issues/2775.
This PR improves that by using the `FindExecutable` and `GetExecutable` functions from ycmd to check if the Python interpreter path exists (and is an executable) and by returning a much more helpful message if it doesn't. We use `FindExecutable` instead of `GetExecutable` on the `g:ycm_server_python_interpreter` option so that the user can specify a Python path with just the executable name (e.g. `python`, `python2`, `python3`).
This also fixes a Python traceback in Vim that occurs when, after successfully starting the server, the `g:ycm_server_python_interpreter` option is set to an invalid path and the server is restarted with `:YcmRestartServer`. Steps to reproduce are:
- start Vim with a working YCM;
- type `:let g:ycm_server_python_interpreter = '/invalid/python/path'`;
- type `:YcmRestartServer`.
