N/A patches for version.c:

vim-patch:8.1.0783: compiler warning for signed/unsigned

Problem:    Compiler warning for signed/unsigned.
Solution:   Add type cast.  Change type of buffer. (Ozaki Kiichi, closes vim/vim#3827)
https://github.com/vim/vim/commit/63c0ccd2b68ce854f294e6f149cc700c7f543674

Neovim was refactored to prefer char type for string functions, not char_u.

vim-patch:8.2.2152: screenpos() does not include the WinBar offset

Problem:    screenpos() does not include the WinBar offset.
Solution:   Use W_WINROW() instead of directly using w_window. (closes vim/vim#7487)
https://github.com/vim/vim/commit/8dd46e72cfb13b8de793c808ee009c45e881903a

W_WINROW() was removed so port only the test changes.
The test is currently skipped.
