Adds the ability to process commands at a new phase during GDB's startup. This phase is earlier than the current initialisation file processing, before GDB has produced any output. The number of commands that can be processed at this early stage will be limited, and it is expected that the only commands that would be processed at this stage will relate to some of the fundamentals of how GDB starts up. Currently the only commands that it makes sense to add to this early initialization file are those like 'set style version ....' as the version string is displayed during startup before the standard initialization files are parsed. As such this commit fully resolved bug cli/25956. This commit adds a mechanism to execute these early initialization files from a users HOME directory, as well as some corresponding command line flags for GDB. The early initialization files that GDB will currently check for are ~/.config/gdb/gdbearlyinit (on Linux like systems) or ~/.gdbearlyinit if the former is not found. The output of 'gdb --help' has been extended to include a list of the early initialization files being processed. gdb/ChangeLog: PR cli/25956 * NEWS: Mention new early init files and command line options. * config.in: Regenerate. * configure: Regenerate. * configure.ac: Define GDBEARLYINIT. * main.c (get_earlyinit_files): New function.
