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.

[READY] Handle keyboard interruption when evaluating Vim expression with user input
When evaluating a Vim expression in Python that involves code expecting user input (e.g. `input()`, `inputlist()`, `complete_check()`, etc.), if this evaluation is interrupted by the user (with `CTRL-C` for instance), Vim will pass the interruption to the Python interpreter which in turn will raise a `KeyboardInterrupt` exception. We don't want these exceptions to be displayed to the user (because the way Vim handles Python exceptions is really annoying) so we catch them where appropriate.
Fixes#2289.

[READY] Do not send BufferVisit and FileReadyToParse notification events when current allowed buffer has not changed
See discussion in PR #2265 and the commit message.
Since only the `BufEnter` autocommand event is concerned, we are splitting `s:OnBufferVisit` in two functions:
- `s:OnBufferRead`, identical to current `s:OnBufferVisit`, for the `BufRead` and `FileType` autocommand events;
- `s:OnBufferEnter` for the `BufEnter` event.
We only send the `BufferVisit` and `FileReadyToParse` event notifications to `ycmd` in `s:OnBufferEnter` when the entered buffer, in which we are allowed to complete, is different from the last one.
Closes#2265.

<!-- Reviewable:end -->
When selecting candidates during completion, Vim jumps to the preview
window (if enabled) and jumps back to the actual buffer, triggering
twice the BufEnter autocommand event. This results in YCM sending
two BufferVisit and one FileReadyToParse event notifications to
ycmd, which is completely unnecessary since the current buffer
did not change. We improve this by only sending these events when the
entered buffer allowed to be completed has changed.
[READY] Avoid hit-enter prompts during completions
Being interrupted by the `Press ENTER or type command to continue` prompt while writing code is annoying. This happens when an error occurs during completion and the error message displayed on the status line is longer than the window width. We prevent that by truncating the message.
Note that the message logged to the command-line history will also be truncated.
4 functions to display messages on the status line (`PostVimMessage`, `PostMultiLineNotice`, `EchoText`, and `EchoTextVimWidth`) is a little too much. Merge them into one.

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.

[READY] Fix diagnostic highlighting at line ending
When highlighting a range of characters for a diagnostic, we make sure that the start and end positions do not go paste the line contents or the range will not be highlighted at all (don't ask, this is a Vim feature). However, we don't account for the end position not being included in the diagnostic range. So, when this position ends at line ending or after it, we move it just before the `EOL` character. Since the end position is not part of the range, this character will not be highlighted, which is not what we want. We fix this behavior by decrementing the end column before clamping it and incrementing it after.
Fixes https://github.com/Valloric/YouCompleteMe/issues/846.

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.
Since version 3.0.0, flake8 does not support Python 2.6, 3.2 and 3.3
anymore. It is still working for our Python 3.3 runs on Travis but
not for the Python 2.6 one so we only disable it for this version.
[READY] Improve extraction of keywords from syntax list
This PR is an attempt at improving the extraction of keywords from Vim syntax files. Current approach is to go through the `syntax list` output and:
- ignore lines where the first word is a reserved keyword for syntax highlighting except for `contained`;
- ignore all words used by Vim as arguments in the syntax commands;
- add remaining words to the list of identifiers.
The main issue with this approach is that syntax arguments that could be valid language keywords are always ignored. There is also a bug where the `match` keyword is extracted while not being a language keyword (see the Python, C++, and Java tests).
With the new approach, we try to ignore Vim keywords only when necessary, that is:
- ignore `syntax match` (fix the `match` keyword bug) and `syntax region` commands: they mostly contain arguments, syntax groups and regular expressions;
- ignore `nextgroup=` if in first position and subsequent arguments `skipempty`, `skipwhite`, and `skipnl`;
- ignore `contained` argument if in first position;
- add remaining words to the list of identifiers.
This strategy is based on observations of the `syntax list` output.

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.
[READY] Rewrite syntax tests
While trying to fix a bug when extracting identifiers from Vim syntax files, I found out that errors from syntax tests are not really helpful because `eq_` assertions don't tell which items are missing when comparing lists (or sets). So, we use matchers from hamcrest instead to get useful assertion errors.
Note that with these changes, we don't test anymore if the value returned by `_KeywordsFromSyntaxListOutput` is a set. I don't think it's an issue but if you feel that's important, we can probably check for it too.
