[READY] Fix smart matching example in documentation
The smart matching example is wrong: `o` can't match `ø` because `ø` is a letter on its own, not a `o` with a combining mark.

[READY] Resend request when extra conf is loaded or ignored
When the client sends a request to the server, if an extra conf file is found that is not already white/blacklisted, the server stops processing the request and tells the client that an unknown extra conf file has been found. The client then asks the user if that file should be loaded or not. Depending on the
user's answer, the client sends a request to the server to load or ignore the extra conf file. Finally, the server loads the file or adds it to the blacklist. However, the initial request was not processed by the server and should be sent again.
Here's a demo illustrating the current situation:
As you can see, the file is not parsed after loading the extra conf file. With the proposed changes:
Fixes#2962.

[READY] Do not return omnifunc suggestions if server crashed
We currently return unfiltered and unsorted suggestions from the omnifunc if the `filter_and_sort_candidates` request failed (generally because the server crashed). This behavior is confusing as it may let the user thinks that YCM is working (in a bad way) while in fact it doesn't. No suggestions should be returned in that case.

[READY] Check if completion is allowed on character events
We should check if completion is allowed when a character is inserted or deleted like we do with the other events.

[READY] Refactor server exception handling
Having to wrap all request calls with the `HandleServerException` function is inconvenient. Handle server exceptions directly in `BaseRequest`.

Allow users to still trigger Vim's omnifunc through C-Space when the
g:ycm_filetype_specific_completion_to_disable option is set for the current
filetype.
[READY] Fix index error when applying a chunk at the end of file
When sending a request to the server, [we add a newline to the buffer contents to match what gets saved to disk](d3381411a0/python/ycm/vimsupport.py (L117)). If the server generates a chunk containing that newline, this chunk goes past the Vim buffer contents since there is actually no new line, which raises an `IndexError` exception when applying the chunk. We fix the issue by recomputing the end position of where the chunk is applied and by removing all trailing characters in the chunk.
Steps to reproduce the issue:
- create a `Test.java` file with the following contents:
```java
package Test;$
$
```
where `$` represents an end of line;
- issue the `:YcmCompleter Format` command.
