This fixes a bug that causes a mangled statusline. The bug occurs, when
the `displayed_head_limit` variable is set and causes the substring
expression to take a substring, which ends in the middle of a multi-byte
character.
This patch replaces the byte-based methods for measuring the
length of the branch name and creating a substring with methods that are
character-based and multi-byte aware.
It also has the nice side effect of making the length measuring more
accurate, by taking the actual display width of multi-byte characters
and the ambiwidth setting into account.
Since we need to take into account older Vim 7.4 (which might not have
the strcharpart() function), do introduce a compatibility wrapper in
airline#util that checks for the existence of the function before using
it. Older Vims will keep on using the byte-based index. I suppose Vim
7.4 before the strcharpart() function was available (patch 7.4.1730)
shouldn't be in use anymore.

You can now specify the special theme name `random` and vim-airline will
load a random theme from the ones installed. This works from either your
.vimrc as well as when calling `:AirlineTheme` command directly.

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

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.
This is no explicit problem in Vim, however Neovim diverged in this
behaviour from Vim and requires the dict attribute to be present before
accessing the self attribute.
See neovim/neovim#5763
airline#system#util for nvim used to fall back to 'system' implementation on
command error. This behavior caused conflict with other plugins if 'util' was
executed with a failing command as part of a ShellCmdPost event.
This commit makes 'util' interpret command error as persistent and not call
'system' in such a case.
This commit fixes#1317.
This commit makes branch.vim use neovim's async jobs instead of a system()
function. This way we avoid the v:shell_error overwrite bug and allow live
updates of the untracked status.
airline#extensions#load() tries to load all extensions,
the user has specified in g:airline_extensions.
However, if e.g. bufferline is requested to be loaded, but
is not installed, it will throw an error
E117: Unknown function: airline#extensions#bufferline#init
Therefore, catch E117 and show a warning.
closes#1127
