Fix MI dprintf-insert not printing on a resolved pending location.
This patch fixes the "Format string required" error when trying to print a dprintf on a now resolved, pending location when set via the MI interface even if the format string is entered correctly. This patch also adds a test case to check that issue called mi-dprintf-pending.exp. gdb/ChangeLog: PR breakpoints/16465 * breakpoint.c (create_breakpoint): Save extra_string for pending breakpoints. gdb/testsuite/ChangeLog: PR breakpoints/16465 * gdb.mi/mi-dprintf-pending.c: New file. * gdb.mi/mi-dprintf-pending.exp: New test. * gdb.mi/mi-dprintf-pendshr.c: New file.
