Auto merge of #2657 - micbou:completion-system-rewrite, r=bstaletic
[READY] Rewrite completion system There is a number of issues with the current completion system: - UI is blocked until the completions are returned by the server, the request timed out, or a key is pressed by the user. This leads to a rough experience when completions take too much time: cursor disappearing and timeout errors (see https://github.com/Valloric/YouCompleteMe/issues/2192 and https://github.com/Valloric/YouCompleteMe/issues/2574). Users even [increase the timeout by manually editing the `completion_request.py` file](https://github.com/Valloric/YouCompleteMe/blob/master/python/ycm/client/completion_request.py#L30) to avoid these errors, which exacerbate the issue and, in some cases, make the plugin unusable (see https://github.com/Valloric/YouCompleteMe/issues/2574). - no fuzzy matching from omnifunc when forcing semantic completion. See https://github.com/Valloric/YouCompleteMe/issues/961; - no fuzzy matching when deleting characters. Vim filtering is used instead:  Neovim and MacVim are not affected. - completion menu disappears after deleting a character and inserting one:  Neovim and MacVim are not affected. - ignore the start column returned by the server. See PR https://github.com/Valloric/YouCompleteMe/pull/2489. - subject to flickers. This one depends a lot on the version of Vim. Completion is almost flicker-free in Neovim and MacVim. Not too bad in console Vim (except in fast terminal like [alacritty](https://github.com/jwilm/alacritty)). Awful in gVim GTK2 (a bit better on GTK3) and gVim on Windows. This PR is an attempt at fixing all of these issues while reducing flickers as best as possible (due to how completion works in Vim, a flicker-free experience is impossible to achieve). Here's how: - poll for completions using a timer and call `completefunc` once the completions are ready. Use the start column returned by the server in `completefunc`; - immediately display the last completions on the `TextChangedI` event to prevent the popup menu disappearing while waiting for the completions. This reduces flickering; - use the `InsertCharPre` event to close the completion menu just before inserting a character. This way the `TextChangedI` event is triggered when the character is inserted (this event is not fired when the completion menu is visible). This replaces the `refresh` option set to `always` in `completefunc` and the `s:cursor_moved` hack; - remap the backspace key to close the completion menu when deleting a character and thus triggering the `TextChangedI` event; - send a request with `force_semantic` set to `True` when forcing semantic completion instead of calling the omnifunc. This fixes the issue where there is no fuzzy matching for custom omnifuncs. Here's a demo where I added a spin animation on the command line while loading the completions to show that it doesn't block the Vim UI:  Fixes #961. Fixes #1282. Fixes #1881. Fixes #2192. Fixes #2500. Fixes #2574. <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/valloric/youcompleteme/2657) <!-- Reviewable:end -->
