This is equivalent to patches 7.4.396, 7.4.445 and 7.4.598.

os_file_is_readonly() in its current form is equivalent to
!os_file_is_writable(). This does not appear to be a bug, because Vim's
use of check_file_readonly() (which we changed to os_file_is_readonly())
is equivalent to !os_file_is_writable() in every case.
os_file_is_readonly() also fails this test:
returns false if the file is non-read, non-write
A more useful form would define behavior under these cases:
- path is executable (but not writable)
- path is non-existent
- path is directory
But there is no reason for os_file_is_readonly() to exist, so remove it.
This is a port of my original contribution to Vim, added in 7.4.687
(https://github.com/vim/vim/commit/v7-4-687). The TUI code has been
heavily refactored (see esp. 25ceadab37),
so this required some translation, but the logic is the same.
Currently, there are two functions in the UI API that are called when
the mode changes: insert_mode() and normal_mode(). These can be folded
into a single mode_change() entrypoint which can do whatever it wants
based on the mode it is passed, limited to INSERT and NORMAL for now.
A menu item can have separate bindings for each Vim mode.
:emenu checks to see which binding it should execute. But, it assumes
it can only be called from Normal mode, so its mode detection is based
on some guesswork. For instance, it detects if you've just used C-O
and, if so, uses the Insert mode binding.
Now that :emenu can be called from any mode (via vim_command), this
commit has it check the actual mode we're in, and simply use the
binding for that mode if we aren't in Normal mode.
