Drop explicit unlock-buffer
This API is unused as of now. Most of the file locking API additions
in Emacs 28 are missing, lock-file, unlock-file, etc. Those have
higher priority.

These functions must be called explicitly via @code{compat-call},
since their calling convention or behavior changed:
-@c copied from lispref/files.texi
-@defun compat-call@ unlock-buffer
-This function unlocks the file being visited in the current buffer,
-if the buffer is modified. If the buffer is not modified, then
-the file should not be locked, so this function does nothing. It also
-does nothing if the current buffer is not visiting a file, or is not locked.
-This function handles file system errors by calling @code{display-warning}
-and otherwise ignores the error.

-@xref{File Locks,,,elisp}.

-This compatibility versions catches the @code{file-error} condition,
-issuing a warning instead of propagating on the error.
-@end defun

@defun compat-call@ string-width string &optional from to
This function returns the width in columns of the string @var{string},
if it were displayed in the current buffer and the selected window.
