[READY] Disable Vim filtering
[Patch 8.1.1123](73655cf0ca) added a new field `equal` to completion items that disable Vim filtering. Since we are using our own filtering, we should always set that field to `1`. This should in theory speed up completion and reduce flickering but I couldn't really notice a difference.

[READY] Fix bold rendering issue in docs
The text `GoTo*` is not rendered in bold because of the asterisk. Instead of escaping the character, we change the text to something more in line with the other bullet points.
In case you are wondering about the other changes in the Vim docs, [I added support for Python 3 to the `html2vimdoc.py` script](2f763ac54f) and this required the change to not break lines on the hyphen character in order to get the same output on both versions of Python (this also has the benefit of not breaking inside a command-line flag like `--java-completer`).

[READY] Update docs to represent new use_clangd flag
After merge of Valloric/ycmd#1191, `use_clangd` option has changed to binary, this patch updates docs to represent that change.
Needs to be merged after `third_party/ycmd` is updated to contain that PR.

- ease Clangd completer initialization;

[READY] Ensure only loclist or quickfix windows are closed
Fixes#3334.
Note that `autocmd! * <buffer>` is required for location lists because we don't want to remove the autocommand in other location lists. It doesn't matter for the quickfix window since there is only one.

[READY] Allow completion in the command-line window
This implements @puremourning's suggestion from https://github.com/Valloric/YouCompleteMe/pull/1415#issuecomment-460197058 and adds an entry in the FAQ on how to override the `TAB` mapping in the command-line window. Since the `CmdwinEnter` event is triggered instead of `BufEnter` in that window, the `s:OnBufferEnter` function is called for that event too. Also, the contents of that window are empty when the filetype is set the first time so we ignore the `FileType` event in that window. Finally, the `qf` filetype is removed from the `g:ycm_filetype_blacklist` option since the quickfix window is always ignored.
This needs testing as these changes may not work well with plugins that create special buffers. We may have to blacklist the filetype of these buffers.

# Why this change is necessary and useful
- The original installation guide missed `go build` in `godef`'s directory, relating issue [here](https://github.com/Valloric/YouCompleteMe/issues/3071#issuecomment-403213723).
- The path of `gocode` and `godef` has been changed, update them in the doc.
I have tested this guide on my Manjaro laptop and it works fine, my go version is `1.11.4`.
(Since the path is too long, the vim help doc looks kind of ugly, maybe the formatting or the
path's presenting way should be changed so that it looks better. I used the `gq` command
in vim and it gave me this.)

# Why this change is necessary and useful
clangd-based completer has been introduced into ycmd for a while now. I believe it is time to let users know about it as well. We are also updating clangd's docs and it would be nice to point people using vim into YCM docs for integration. You can see the patch for that one in https://reviews.llvm.org/D56718.
Also you can have a look at the end product of the changes at https://kadircet.github.io/YouCompleteMe

[READY] Improve error message when unable to load Python
The current error when Python cannot be loaded
> YouCompleteMe unavailable: requires Vim compiled Python (2.7.1+ or 3.4+) support.
is misleading if Vim has been dynamically compiled against Python but is unable to find the library. See issue https://github.com/Valloric/YouCompleteMe/issues/3300 for instance. We should only return that error if `has( 'python_compiled' )` and `has( 'python3_compiled' )` are both false. Furthermore, we should check if Python 3 is available before Python 2 because on some platforms, only one Python library can be loaded at a time so if Python 2 is loaded first, Python 3 cannot be used.

Check explicitely that Vim is compiled with Python support.
Attempt to load Python 3 before Python 2 since only one can be loaded at
a time on some platforms. Return an appropriate error if unable to load
both.

# Why this change is necessary and useful
The issue was originally reported at https://github.com/neovim/neovim/issues/6840.
If I exit neovim immediately after it starts, there are error messages like this:
```
Error detected while processing function <SNR>96_PollServerReady[1]..<SNR>96_Pyeval[2]..provider#python3#Call:
line 18:
Invalid channel: 3
Error detected while processing function <SNR>96_PollServerReady[7]..<SNR>96_Pyeval[2]..provider#python3#Call:
line 18:
Invalid channel: 3
```
The issue is not always reproducible. Usually I get once in 5 neovim runs. With this patch I don't get these message in 20 neovim runs.
In https://github.com/neovim/neovim/issues/6840#issuecomment-309960751, @micbou mentions that
> Stopping the timers on the `VimLeave` event seems to fix that issue
So, here's my attempt!

[READY] Update sign place regex pattern for newer versions
Among other things, [Vim 8.1.0614](162b71479b) changed the output of the `sign place` command by adding the `priority` field:
```
--- Signs ---
Signs for test.cpp:
line=4 id=100000000 name=YcmError priority=10
line=5 id=100000001 name=YcmError priority=10
```
This breaks [the `GetSignsForBuffer` function](7997fc5536/python/ycm/vimsupport.py (L204-L215)) which extract the signs from the output of that command. We need to update the regex pattern used to match the lines of `sign place` for Vim 8.1.0614 or later.
