The 'hidden' option is a global option, not a buffer one. If this option is
false, we should check if the 'bufhidden' option, which is local to the buffer,
is set to 'hide'. If so, the buffer can be hidden despite the 'hidden' option
being false.
Bring fully asynchronous completion by polling for completions with a timer
then calling completefunc once the completions are ready. Use the start column
returned by the server in completefunc. Immediately display the last completion
on the TextChangedI event to prevent the popup menu disappearing while waiting
for the completions. Handle the TextChangedI event not being triggered while
the completion menu is open by closing the menu when inserting a character
through the InsertCharPre event, and when deleting a character on the <BS> and
<C-h> keys.
[READY] Use codepoint offsets in identifier functions
`CurrentIdentifierFinished` and `LastEnteredCharIsIdentifierChar` incorrectly use byte offsets with unicode lines (`CurrentColumn` returns a byte offset and `CurrentLineContents` a unicode string). This leads to weird bugs when there is a non-ASCII character on the current line:
This is fixed by converting byte offsets to codepoint ones through the `ByteOffsetToCodepointOffset` function.
This changes the behavior of these two functions when the current column position is invalid. Both functions returned false in that case. They now return as if the current column were at the end of the line. In practice, this doesn't really matter since the position of the current column should always be valid.

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

# 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.
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.
When an error occurs during completions, a message is displayed on
the status line. If this message is longer than the width of the
current window, Vim will prompt the user to press enter or type a
command to hide the message, interrupting user workflow. We prevent
that by truncating the message to window width.
Merge PostMultiLineNotice, EchoText, and EchoTextVimWidth functions
into PostVimMessage.
When columns are clamped to not be past the contents of the line for
highlighting diagnostics, we need to account for the column end not
being included in the diagnostic range.
Use the following strategy to extract identifiers from syntax
highlighting:
- ignore match and region: they mostly contain arguments,
syntax groups and regular expressions;
- ignore "nextgroup=" if first word and subsequent arguments
"skipempty", "skipwhite", and "skipnl";
- ignore "contained" argument if first word;
- add remaining words to the list of identifiers.
Fix a bug where the word "match" was extracted while not being a keyword
of the syntax language.
Do not convert strings to bytes but instead use plain strings to mimic
Vim buffers returning a list of byte objects on Python 2 and unicode
objects on Python 3.
Open the quickfix window to full width at the bottom of the screen with
its height set to fit all entries. This behavior can be overridden by
using the YcmQuickFixOpened autocommand.
Add a new section for autocommands in the documentation.
Update GoTo and ReplaceChunks tests.
On Windows and Python 2, the full exception message from IOError
in CheckFilename will contain the filepath formatted as a unicode
string. Since the filepath is already added in the RuntimeError
message, use the strerror attribute to only display the error.
Move PostComplete tests inside a class that defines setUp and tearDown
methods. Clean YCM object in tearDown method. This fixes the error
"OSError: [WinError 6] The handle is invalid" on Windows with
Python 3.5.
Python 3 is much stricter around mixing bytes with unicode (and by
"stricter," I mean it doesn't allow it at all) so we're making
vimsupport only return `unicode` objects (`str` on py3). The idea is
that YCM (and ycmd) internals only ever deal with unicode.
We simply apply the changes to each file in turn. The existing replacement
logic is unchanged, except that it now no longer implicitly assumes we are
talking about the current buffer.
If a buffer is not visible for the requested file name, we open it in
a horizontal split, make the edits, then hide the window. Because this
can cause UI flickering, and leave hidden, modified buffers around, we
issue a warning to the user stating the number of files for which we are
going to do this. We pop up the quickfix list at the end of applying
the edits to allow the user to see what we changed.
If the user opts to abort due to, say, the file being open in another
window, we simply raise an error and give up, as undoing the changes
is too complex to do programatically, but trivial to do manually in such
a rare case.
Moved File parse request handling and diagnostic extraction flow into
python to simplify flow and allow easier addition of new parse request
handlers such as semantic highlighter.
Refactored base_test to patch separate vimsupport functions instead of
the whole module, and interfering the test results afterwards.
Added new tests for diagnostic sign place/unplace and error/warning
count extraction API.
[READY] Fix issue in EventNotification tests
While I was reviewing PR #1905, I found an issue with the `EventNotification` tests. It's easy to reproduce. You just need to comment [this line in `python/ycm/youcompleteme.py`](https://github.com/Valloric/YouCompleteMe/blob/master/python/ycm/youcompleteme.py#L508) and run the tests. With this change, the `EventNotification` tests should fail since the second call of `ValidateParseRequest` re-raises the warning. However, tests are still passing because `assert_has_calls` does not check if a call was not made. For example, if `functionA` is called twice, both `assert_has_calls( [ functionA ] )` and `assert_has_calls( [ functionA, functionA ] )` are successful.
To fix this, we just need to check the number of calls using `call_count`. This is done by creating a subclass of `MagicMock` implementing the `assert_has_exact_calls` method and using it in tests.

[READY] Implement new strategy to find the Python interpreter path
See discussion in issue #1891 for details.
Implement a new strategy to find the Python interpreter path:
- if specified, use `g:ycm_path_to_python_interpreter` option.
- on UNIX platforms, use `sys.executable` as the path to Python interpreter;
- on Windows, deduce it from `os.__file__` path (it should always be in the parent folder).
In all cases, check the version (2.6 or 2.7) of the Python interpreter path by running it.
This PR may break things. It needs thorough testing.

assert_has_calls is not enough to check if a call didn't raise a
warning. We also need to check the number of calls. This is done by
creating a subclass of MagicMock implementing the
assert_has_exact_calls method.
OmniCompletionRequest is missing the RawResponse method, so any attempt to call
it calls the base class method instead. However, since the data structures of
this class and base class are different, this causes an error.
