FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
Problem: [security]: FPE in adjust_plines_for_skipcol
Solution: don't divide by zero, return zero
Prevent a floating point exception when calculating w_skipcol (which can
happen with a small window when the number option is set and cpo+=n).

Problem: [security]: overflow in nv_z_get_count
Solution: break out, if count is too large
When getting the count for a normal z command, it may overflow for large
counts given. So verify, that we can safely store the result in a long.

We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.

This makes the type suboptimal for a codebase meant to be

The screen grid refactors will continue until morale improves.
Jokes aside, this is quite a central installment in the series.
Before this refactor, there were two fundamentally distinct codepaths
for getting some text on the screen:
- the win_line() -> grid_put_linebuf() -> ui_line() call chain used for
buffer text, with linebuf_char as a temporary scratch buffer
- the grid_line_start/grid_line_puts/grid_line_flush() -> ui_line()
path used for every thing else: statuslines, messages and the command line.
Here the grid->chars[] array itself doubles as a scratch buffer.
With this refactor, the later family of functions still exist, however
they now as well render to linebuf_char just like win_line() did, and
grid_put_linebuf() is called in the end to calculate delta changes.
This means we don't need any duplicate logic for delta calculations anymore.
Later down the line, it will be possible to share more logic operating
on this scratch buffer, like doing 'rightleft' reversal and arabic
shaping as a post-processing step.
This is a step in an ongoing refactor where the "grid_puts" and
"grid_put_linebuf" code paths will share more of the implementation (in
particular for delta calculation, doublewidth and 'arabicshape'
handling). But it also makes sense by its own as a cleanup, and is thus
committed separately.
Before this change many of the low level grid functions grid_puts,
grid_fill etc could both be used in a standalone fashion but also as
part of a batched line update which would be finally transmitted as a
single grid_line call (via ui_line() ). This was initially useful to
quickly refactor pre-existing vim code to use batched logic safely.
However, this pattern is not really helpful for maintainable and newly
written code, where the "grid" and "row" arguments are just needlessly
repeated. This simplifies these calls to just use grid and row as
specified in the initial grid_line_start(grid, row) call.
This also makes the intent clear whether any grid_puts() call is actually
part of a batch or not, which is better in the long run when more things
get refactored to use effective (properly batched) updates.
Problem: r_CTRL-C works differently in visual mode
Solution: Make r_CTRL-C behave consistent in visual mode
in terminal and Windows GUI
in visual mode, r CTRL-C behaves strange in Unix like environments. It
seems to end visual mode, but still is waiting for few more chars,
however it never seems to replace it by any characters and eventually
just returns back into normal mode.
In contrast in Windows GUI mode, r_CTRL-C replaces in the selected area
all characters by a literal CTRL-C.
Not sure why it behaves like this. It seems in the Windows GUI, got_int
is not set and therefore behaves as if any other normal character has
been pressed.
So remove the special casing of what happens when got_int is set and
make it always behave like in Windows GUI mode. Add a test to verify it
always behaves like replacing in the selected area each selected
character by a literal CTRL-C.

Most of the messy things when changing a non-current buffer is
not about the buffer, it is about windows. In particular, it is about
`curwin`.
When editing a non-current buffer which is displayed in some other
window in the current tabpage, one such window will be "borrowed" as the
curwin. But this means if two or more non-current windows displayed the buffers,
one of them will be treated differenty. this is not desirable.
In particular, with nvim_buf_set_text, cursor _column_ position was only
corrected for one single window. Two new tests are added: the test
with just one non-current window passes, but the one with two didn't.
Two corresponding such tests were also added for nvim_buf_set_lines.
This already worked correctly on master, but make sure this is
well-tested for future refactors.
Also, nvim_create_buf no longer invokes autocmds just because you happened
to use `scratch=true`. No option value was changed, therefore OptionSet
must not be fired.
ml_get_buf() takes a third parameters to indicate whether the
caller wants to mutate the memline data in place. However
the vast majority of the call sites is using this function
just to specify a buffer but without any mutation. This makes
it harder to grep for the places which actually perform mutation.
Solution: Remove the bool param from ml_get_buf(). it now works
like ml_get() except for a non-current buffer. Add a new
ml_get_buf_mut() function for the mutating use-case, which can
be grepped along with the other ml_replace() etc functions which
can modify the memline.

Problem: can't move to last non-blank char
Solution: Make g<end> behave like that
Make it possible to move to last non-blank char on a line
We can distinguish between g0 and g^ to move to the very first character
and the first non-blank char.
And while we can move to the last screen char, we cannot go to the last
non-blank screen char.
Since I think g$ is the more widely used and known movement command (and
g<end> is synonymous to it) change the behaviour of g<end> to move to
last non-screen char instead and don't have this be the same command as
the g$ command anymore.
If you want to keep the old behaviour, you can use:
```
nnoremap g<end> g$
```
Add a test to verify the behaviour.

changed between two checks.
Problem: Cursor not adjusted when near top or bottom of window and

Adds new API helper macros `CSTR_AS_OBJ()`, `STATIC_CSTR_AS_OBJ()`, and `STATIC_CSTR_TO_OBJ()`, which cleans up a lot of the current code. These macros will also be used extensively in the upcoming option refactor PRs because then API Objects will be used to get/set options. This PR also modifies pre-existing code to use old API helper macros like `CSTR_TO_OBJ()` to make them cleaner.
