Simon Marchi 6bd434d6ca gdb: make some variables static
I'm trying to enable clang's -Wmissing-variable-declarations warning.
This patch fixes all the obvious spots where we can simply add "static"
(at least, found when building on x86-64 Linux).

gdb/ChangeLog:

	* aarch64-linux-tdep.c (aarch64_linux_record_tdep): Make static.
	* aarch64-tdep.c (tdesc_aarch64_list, aarch64_prologue_unwind,
	aarch64_stub_unwind, aarch64_normal_base, ): Make static.
	* arm-linux-tdep.c (arm_prologue_unwind): Make static.
	* arm-tdep.c (struct frame_unwind): Make static.

	Make static.
	* infrun.c (observer_mode): Make static.
	* linux-nat.c (sigchld_action): Make static.
	* linux-thread-db.c (thread_db_list): Make static.
	* maint-test-options.c (maintenance_test_options_list):
	* mep-tdep.c (mep_csr_registers): Make static.
	* mi/mi-cmds.c (struct mi_cmd_stats): Remove struct type name.
	(stats): Make static.
	* nat/linux-osdata.c (struct osdata_type): Make static.

	static.
