Add two widget callbacks:
* (make_global): convert widget coordinates from local (relative to
owner) to global (screen).
* (make_local): convert widget coordinates from global (screen) to
local (relative to owner).
Such conversions are required when nested widgets and groups are added to
or removed from another groups.

foot is a "fast, lightweight and minimalistic Wayland terminal emulator"
(see https://codeberg.org/dnkl/foot). Add its default TERM value to the
recognized ones. This enables mc to change the terminal window title and
handle mouse events.
(tty_check_term): add support of foot terminal emulator as xterm-compatible.

The build system runs configure script after switching to another branch
or changeset, which basically means that each git operation which
modifies HEAD will cause a full rebuild. This is highly annoying, in
particular during bisecting.
Solution:
Don't define version in config.h.
Add mc_version member to mc_global_t structure and use it instead of
VERSION macro.
Now only lib/global.c depends on MC version.

...to free or not to free the string representation
of vfs_path_t object.
It allows to get rid of string duplication in following cases:
vfs_path_t *vpath;
char *path;
...
vpath = vfs_path_from_str (...);
path = g_strdup (vfs_path_as_str (vpath));
vfs_path_free (vpath);
Now we can write:
vfs_path_t *vpath;
char *path;
...
vpath = vfs_path_from_str (...);
path = vfs_path_free (vpath, FALSE);
