- Removed term.c, term.h and term_defs.h
- Tests for T_* values were removed. screen.c was simplified as a
consequence(the best strategy for drawing is implemented in the UI layer)
- Redraw functions now call ui.c functions directly. Updates are flushed with
`ui_flush()`
- Removed all termcap options(they now return empty strings for compatibility)
- &term/&ttybuiltin options return a constant value(nvim)
- &t_Co is still available, but it mirrors t_colors directly
- Remove cursor tracking from screen.c and the `screen_start` function. Now the
UI is expected to maintain cursor state across any call, and reset it when
resized.
- Remove unused code
- Remove abstract_ui global, now it is always active
- Remove some terminal handling code
- Remove unused functions
- Remove HAVE_TGETENT/TERMINFO/TERMIOS/IOCTL #ifdefs
- Remove tgetent/terminfo from version.c
- Remove curses/terminfo dependencies
- Only start/stop termcap when starting/exiting the program
- msg_use_printf will return true if there are no attached UIs(
messages will be written to stdout)
- Remove `ex_winpos`(implement `:winpos` with `ex_ni`)
Problem : Out-of-bounds access @ 5815.
Diagnostic : False positive.
Rationale : Error occurs when event_name2nr() returns NUM_EVENTS, which
means an event with that name was not found. That cannot
happen, as previous check using find_end_event() @ 5744
ensures event name exists.
Resolution : Assert event_name2nr() result is less thatn NUM_EVENTS.
Regarding dict_lookup() in eval.c: both definitions are the same, the
only difference being the spacing between the indirection operator and
the indentation level.
Problem: A TextChanged autocommand is triggered when saving a file.
(William Gardner)
Solution: Update last_changedtick after calling unchanged(). (Christian
Brabandt)

Problem : Exlicit null dereferenced (FORWARD NULL) @ 2859.
Diagnostic : Real issue.
Rationale : Code within `if (!p_bk)` seems to assume `backup` not null
at that point, which may not be true.
Resolution : Don't enter conditional on null `backup`.
Nvim now relies much less on setting terminal mode to cooked mode, remove most
calls to settmode, except for those that happen on startup or when suspending.
Eventually even those will be handled by the UI layer.
Problem : Dereference of null pointer @ 6219.
Diagnostic : False positive.
Rationale : Problem occurs if `aucmd_win` is NULL after
`win_alloc_aucmd_win()`, which cannot happen since it uses
new memory functions. So, this is a leftover since OOM
refactorization.
Resolution : Remove dead code.
Problem : Dead assignment @ 1754.
Diagnostic : Harmless issue.
Rationale : It's true `iconv_fd` is not going to be used again (we are
in the failure handler). But what is being done (assigning
sentinel value to mark as "empty" after destroying) is in
fact good practice, which could turn significant if more
code is added later on. So, we don't want to remove this.
Resolution : Leave it there, but exclude from analysis.
Problem: ml_get error for autocommand that moves the cursor of the
current window.
Solution: Check the cursor position after switching back to the current
buffer. (Christian Brabandt)
https://code.google.com/p/vim/source/detail?r=v7-4-436
Problem: Possible crash when an BufLeave autocommand deletes the buffer.
Solution: Check for the window pointer being valid. Postpone freeing the
window until autocommands are done. (Yasuhiro Matsumoto)

Feature description from Vim documentation:
NOTE: this code is currently disabled, as the RISC OS implementation was
removed. In the future this will use the 'filetype' option.
On operating systems which support storing a file type with the file, you can
specify that an autocommand should only be executed if the file is of a
certain type.
The actual type checking depends on which platform you are running Vim
on; see your system's documentation for details.
To use osfiletype checking in an autocommand you should put a list of types to
match in angle brackets in place of a pattern, like this: >
:au BufRead *.html,<&faf;HTML> runtime! syntax/html.vim
This will match:
- Any file whose name ends in ".html"
- Any file whose type is "&faf" or "HTML", where the meaning of these types
depends on which version of Vim you are using.
Unknown types are considered NOT to match.
Problem: Bug was introduced because `os_open` returns `-errno` in case
of an error instead of just `-1` which was returned by `mch_open`.
Solution: Check return value with `< 0` instead of `== -1`.
Though this module is relatively small it has very clear boundaries.
The last argument for extracting `tempfile` was the errors which I got
when I was writing unittests for it: `cimport './src/nvim/fileio.h'`
does not work for some reason.
