Whitespace Character U+2632 changed to double-width with Unicode release
16 (Vim patch v9.1.736). This causes issues with the statusline like
adding wrapping.
So let's mark that character back as single width, since that is what
most underlying libraries seem to expect.

I noticed, that in some environments the default
g:airline_symbols[notexists] just does not show up, even when the same
font in the gui works. So let's at least mention a possible alternative,
that you can easily use in your vimrc:
```vim
if !exists("g:airline_symbols")
let g:airline_symbols = {}
endif
let g:airline_symbols.notexists = "\u2204"
```
Back when the colnr symbol was first introduced in
8929bc72a1 it included symbol `\ue0a3`
when powerline fonts where supposed to be used by setting
`:let g:airline_powerline_fonts=1`
However, it turns out, that those symbol, may actually not be defined in
the powerline fonts at all, only in the
[powerline-extra-symbols](https://github.com/ryanoasis/powerline-extra-symbols)
and this has caused various issues, because it either did not display at
all, or the symbol caused strange overflowing issues which made the
overall look of the status line not very appealing and already caused
various issues here in the vim-airline repository.
Therefore, fall back to the symbol `\u2105` (℅) which at least is
already defined in the Unicode specification and has therefore a higher
chance of being defined inside a powerline font at all (but it may still
be missing after all).
Also, it is more consistent, because it will now use the same symbol as
when `g:airline_powerline_fonts` is not defined and the default Unicode
symbols are selected.
So if you want to keep on using the old symbol, you need to use:
```
let g:airline_symbols.colnr="\ue0a3:"
```

coc.nvim exposes the name of the function the cursor is currently in
through b:coc_current_function.
For this to work, the key coc.preferences.currentFunctionSymbolAutoUpdate
must be set to 'true' in the coc config.
The value is only updated on CursorHold, so the value may not always be
accurate when moving around.
This is needed for Neovim, because an external UI could be attached to
the same neovim server, so it does not make sense to define highlighting
groups with either only the cterm or the guifg attribute set.
So refactor the code slightly got get rid of this variable (and since
this variable is not needed anymore, we can also get rid of the guienter
and OptionSet autocommand).

vim-airline by default already tries to load theme names, that have the
same name as the colorscheme. Therefore, it does not make sense, to add
mappings that result in the same theme name.
So drop the base16, wombat, zenburn and solarized keys
This removes the hardcoded minwidth limits for both the `hunks` and
`branch` parts. It replaces these with safe accesses to the `minwidth`
setting as done by `airline#parts#define_minwidth`.
This is an experimental feature that allows to display the statusline in
the tabline. It might still be a bit rough, but seems to work so far.
Remaining problem:
- Mode changes are not immediately detected, only after moving the
cursor
