Add MI "-break-insert --qualified"

Currently -break-insert always creates a wildmatching breakpoint, and
there's no way to ask for a fullname match.  To address that, this
patch adds the equivalent of "break -qualified" to MI:

  "-break-insert --qualified".

For the testcase, curiously, it doesn't look like we have _any_
testcase that tests a breakpoint with multiple locations, and, the
existing mi_create_breakpoint / mi_make_breakpoint procedures are only
good for breakpoints with a single location.  This patch thus adds a
few new companion routines to mi-support.exp for breakpoints with
multiple locations: mi_create_breakpoint_multi,
mi_make_breakpoint_loc, mi_make_breakpoint_multi.

 *** Changes since GDB 10
 
+* MI changes
+
+ ** '-break-insert --qualified' and '-dprintf-insert --qualified'
+
+    The MI -break-insert and -dprintf-insert commands now support a
+    new "--qualified" option that makes GDB interpret a specified
+    function name as a complete fully-qualified name.  This is the
+    equivalent of the CLI's "break -qualified" and "dprintf
+    -qualified".
