Add support for --start option in -exec-run GDB/MI command.
gdb/ChangeLog:
* mi/mi-main.c (run_one_inferior): Add function description.
Make ARG a pointer to an integer whose value determines whether
we should "run" or "start" the program.
(mi_cmd_exec_run): Add handling of the "--start" option.
Reject all other command-line options.
* NEWS: Add entry for "-exec-run"'s new "--start" option.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Program Execution): Document "-exec-run"'s
new "--start" option.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-start.c, gdb.mi/mi-start.exp: New files.
