Use these words and casing more consistently across text, comments and one curl tool output: AIX, ALPN, ANSI, BSD, Cygwin, Darwin, FreeBSD, GitHub, HP-UX, Linux, macOS, MS-DOS, MSYS, MinGW, NTLM, POSIX, Solaris, UNIX, Unix, Unicode, WINE, WebDAV, Win32, winbind, WinIDN, Windows, Windows CE, Winsock. Mostly OS names and a few more. Also a couple of other minor text fixups. Closes #14360
