commit 232b641 did unfortunately disable tagbar completely, since
exists("*func") does not autoload the function.
So this time, try explicitly calling the function once, and if it does
not exists, it should be disabled and not cause any further errors.

rename g:airline#init#async variable to g:airline#init#vim_async
because that is what it is for: showing whether vim supports async. Is
not set vor nvim, because nvim always supports jobs.
When using vim-gitgutter and fugitive:
The hunks extension and the branch extension work as expected when the
file is first loaded; both parts are added to the statusline.
Once the cursor is moved and stopped for &updatetime ms:
1. The branch extension clears b:airline_head on CursorHold
2. Somehow (?) airline#statusline gets called on CursorHold
3. The hunks extension returns '' when b:airline_head is empty, causing
the hunks to be removed from the statusline.
It doesn't make sense to clear airline_head just because the cursor
moved, and the commit message adding the line doesn't say why:
13297cee03
Commit 174b7e1962 relies on airline_head
being set.

Commmit a10d321809 introduced a small typo
spelling a previously set variable `trailing_fmt` as `trailing_fm`. This
causes Vim to report `trailing_fm` as an undefined variable. In this
change, the variable is properly referenced as `trailing_fmt`.
calling settabvar() while evaluating the 'tabline' setting apparently
causes flicker on Windows. Fall back to using `:let t:var` to store the
content in the current tabpage.
This is not as good as using `settabvar()` since we cannot store the
title for other tabs, but at least it should prevent the flicker and at
the same time at least cache the title for the current tabpage.
do not call airline#extensions#branch#head() but instead use the cached
variable b:airline_head.
Note: it looks like GitGutterGetHunkSummary() could need some cacheing
Currently, vim-airline will check untracked status for files e.g. living
in .git. So when editing .git/config it will show as being untracked.
While technically, this is correct I prefer not to see this for those
files. So skip the check for those files.
