We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.

vim_strsave() is replaced by expand_env_save_opt(), which expands ~ for
convenience:
:profile start ~/.nvim/prof.log
Prior to this change you had to specify an absolute path.

Also remove some MS-DOS references on lines already being touched.

- 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`)

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 : getdigits() currently returns a long, but at most places,
return value is casted (unsafely) into an int. Making casts
safe would introduce a lot of fuss in the form of assertions
checking for limits.
Note : We cannot just change return type to int, because, at some
places, legitimate long values are used. For example, in
diff.c, for line numbers.
Solution : Introduce new functions:
- get_digits() : Gets an intmax_t from a string.
- get_int_digits() : Wrapper for ints.
- get_long_digits() : Wrapper for longs.
And replace getdigits() invocations by the appropiate
wrapper invocations.

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 : Uninitialized argument value @ 2485.
Uninitialized argument value @ 2507.
Diagnostic : Multithreading issues.
Rationale : Error can only occur if globals `do_profiling`, `time_fd`
are modified while function is executing.
Resolution : Use local copy of globals.

Problem : Dereference of null pointer @ 2462.
Diagnostic : False positive.
Rationale : Error occurred if neither loop neither following if were
entered (this implied `script_items.ga_len < 0`, which
should not be possible).
Resolution : Assert not negative length (loop or if entered).

This is required by the msgpack-RPC specification. Also, the
send_call/send_event functions were refactored to accept a variable number of
arguments

Reuse the profiling functions to implement the startuptime functions.
Decreases our dependency on `gettimeofday()` and thus gets us a little bit
closer to a clean port to Windows.

This uses the provider/scripting infrastructure to reintroduce python support
through the msgpack-rpc API.
A new 'initpython' option was added, and it must be set to a command that will
bootstrap the python provider the first time it's needed.

This uses the provider module infrastructure to implement common code for
vimscript commands/functions that need to communicate with external
interpreters, eg: pydo, rubydo, pyfile, rubyfile, etc.

It wasn't used anywhere else, our coding guidelines mandate the tightest

Should be better than gettimeofday() since libuv uses higher resolution
clocks on most UNIX platforms. Libuv also tries to use monotonic clocks,
kernel bugs notwithstanding, which is another win over gettimeofday().
Necessary for Windows, which doesn't have gettimeofday(). In vanilla vim,
Windows uses QueryPerformanceCounter, which is the correct primitive for
this sort of things, but that was removed when slimming up the codebase.
Libuv uses QueryPerformanceCounter to implement uv_hrtime() on Windows so
the behaviour of vim profiling on Windows should now be the same.
The behaviour on Linux should be different (better) though, libuv uses more
accurate primitives than gettimeofday().
Other misc. changes:
- Added function attributes where relevant (const, pure, ...)
- Convert functions to receive scalars: Now that proftime_T is always a
(uint64_t) scalar (and not a struct), it's clearer to convert the
functions to receive it as such instead of a pointer to a scalar.
- Extract profiling funcs to profile.c: make everything clearer and reduces
the size of the "catch-all" ex_cmds2.c
- Add profile.{c,h} to clint and -Wconv:
- Don't use sprintf, use snprintf
- Don't use long, use int16_t/int32_t/...

- use return value instead of open_req.result
- libuv uv_fs_open() returns `-errno` instead of always -1
- libuv always sets open_req.result to the return value, _except_ for OOM
where it only sets the return value. So always use the return value.
- replace calls to mch_open macro.
- update call sites expecting -1 error

C89 did not have round(), vim emulated it with vim_round. But since we're
using C99 this is not a problem anymore.
