FYI now with the patchset checked in the inability to place a breakpoint on the
real filename is now fixed, so the xfullpath vs. gdb_realpath displayed
filename even should not matter anymore.

$ gcc -o toto toto.c -g
$ ls -l toto*

Because gdb_realpath and compare_filenames_for_search are now always applied
(respecting set basenames-may-differ so it should have no real performance
impact).
