[READY] Use SetQuickFixList function for GoTo* subcommands
From discussion in PR #2101, we reuse the `SetQuickFixList` function for the `GoTo*` subcommands. This automatically makes the quickfix window height equal to the number of locations.
Unfortunately, there is no Vim option to change the default height (10) of the quickfix window so we can't really use the heuristic `min(number of Locations, default height)` because users would not be able to change the default height (and we don't want to add another option). However, there are still solutions to set a default height. For instance, a user could add the following line in its vimrc:
```viml
autocmd FileType qf exe "20wincmd _"
```
to set the default height to 20. This will override YCM behavior.
I didn't reproduce the `lazyredraw` boilerplate from `youcompleteme#OpenGoToList`. I guess it was used to avoid flickering but I didn't experienced any without it. In addition, it was not properly implemented because the `lazyredraw` state was not preserved if the option was already set.
I also threw away the `cclose` command. It resets the quickfix window to its default position if already opened, which I think is not a desirable behavior.
Closes#2101.

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.

The golang details in the README are different than details for other additional languages. Adding a link to the golang download page and updating the wording makes the languages look the same.

# Why this change is necessary and useful
There are a number of recent errors with unicode (most of which caused by the server, see PR https://github.com/Valloric/ycmd/pull/455. In testing I fixed a number of client-side tracebacks also.
This is by no means a comprehensive set of fixes for the client - I have simply fixed those that I came across in testing.
Summary:
- fixes for errors when typing in c-sharp files due to the completion done handler
- fixes for FixIts to apply correctly with multi-byte characters
- fixes for unicode characters in return from the omni completer

[READY] Avoid evaluating Vim globals in Python
### Problem
See the commit message and issue #2127.
### How to reproduce
Make Vim to use Python 3 for YCM by either using Vim with only Python 3 support or by editing the `s:UsingPython2` function in `autoload/youcompleteme.vim` to always return 0.
Create the following `vimrc`:
```
set nocompatible
set runtimepath+=~/.vim/bundle/YouCompleteMe
set encoding=utf8
filetype plugin indent on
let g:dummy_variable = '€'[0]
```
and start Vim with it. The following error will occur:
```
YouCompleteMe unavailable: 'utf-8' codec can't decode byte 0xe2 in position 0: unexpected end of data
```
with the traceback in `:messages`:
```python
Traceback (most recent call last):
File "<string>", line 24, in <module>
File "C:\\Users\\micbou\\.vim\\bundle\\YouCompleteMe\\autoload\..\python\ycm\setup.py", line 49, in SetUpYCM
base.LoadJsonDefaultsIntoVim()
File "C:\\Users\\micbou\\.vim\\bundle\\YouCompleteMe\\autoload\..\python\ycm\base.py", line 60, in LoadJsonDefaultsIntoVim
vimsupport.LoadDictIntoVimGlobals( vim_defaults, overwrite = False )
File "C:\\Users\\micbou\\.vim\\bundle\\YouCompleteMe\\autoload\..\python\ycm\vimsupport.py", line 305, in LoadDictIntoVimGlobals
extend_option ) )
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe2 in position 0: unexpected end of data
```
### Solution
Do not evaluate the Vim globals when loading the YCM default options into Vim and when building the options for the ycmd server.
Depending on the number of global variables and custom YCM options, this may be slower or faster than the current code but by a negligible margin (~1ms).
Fixes#2127 and #2150.

<!-- Reviewable:end -->
On Python 3, evaluating a Vim expression will raise a unicode exception
if it contains an invalid sequence of bytes for the current encoding.
We can't really do anything about it because this is the way Vim and
Python 3 interact. However, we can prevent this situation to occur by
not evaluating Vim data that we have no control over: in particular,
the Vim globals. This is done by:
- adding one by one the YCM default options instead of extending the
Vim globals with them;
- only evaluating the Vim global variable names (and not their values)
when building the YCM options for the ycmd server.
Display an error message to the user depending on the status code
returned by the ycmd server.
Remove ycm_core checks in plugin/youcompleteme.vim. These checks are
now done by the ycmd server.
Do not start a separate process to check the core version but rely on
ycmd returning a specific exit code. This slightly improves the Vim
startup time.
[READY] Fix PostComplete test
A refactoring of PostComplete tests made the `GetCompletionsUserMayHaveCompleted_ReturnEmptyIfPendingMatches_OldVim` test identical to
`GetCompletionsUserMayHaveCompleted_ReturnEmptyIfPendingMatches_NewVim`. Revert to original test.
This PR also updates the tests with small changes. See the commit message.
