Add 'arduino' filetype to list of C-like languages. This is needed in
order to avoid mix-indent-file warnings when using hard tabs for
indentation in Arduino source files (*.ino, *.pde) containing top level
block comments with leading space before a '*'.

for some reasons, calling async functions might cause an error, if a
SourcePre command has been defined. So explicitly call the functions
using `:noa` modifier to prevent triggering the SourcePre autocommand.

- Make sure to always call the term extension on TermOpen autocommands
- consistently use the airline_term highlighting group
- hard code the airline_term highlighting group, because by the time the
function airline#themes#patch() is called the highlighting group
airline_c would no be defined, so we cannot dynamically get those
attributes
- In the documentation, mention how the g:airline_mode_map can be set
including the terminal section
The default formatter uses a hand-build regexp for shortening the path
in the tabline. However, since it uses the \w regex atom, this won't
match e.g. cyrillic letters.
To fix this, use the builtin pathshorten() function which does handle
this case correctly. For a test, use e.g. 'D/Учёба/t.c'
closes#1737
this caused that the branch extension was not correctly working anymore
because of a refactoring of fugitive tpope/vim-fugitive@5d11ff7
Solution: Move the existence check for the fugitive plugin into a
separate function and call it from there in all places that check the
fugitive plugin. Do the same for lawrencium and vcscommand check.
fixes#605#1739
Startify unfortunately does not set the buftype option, so the
`[noperm]` would be shown, since the buffer is not really a file.
(see mhinz/vim-startify#324)
So allow to blacklist startify from this setting. To do so, the logic
from the tabline extension was refactored out into a separate function
that returns true, if the buffer matches
`g:airline#extensions#tabline#ignore_bufadd_pat` and that function is
then reused for the readonly() function as well.
Recently, NERDTree added the &readonly setting to its buffer.
Unfortunately, this caused airline to render the '[noperm]' string in
it.
Fix this by only making the readonly check for buffers that actually
represent files (e.g. the buftype option is empty).
