Change return type of gdbarch_software_single_step to vector<CORE_ADDR>

This is a relatively straightforward patch that changes
gdbarch_software_single_step so it returns an std::vector<CORE_ADDR>
instead of a VEC (CORE_ADDR).

gdb/ChangeLog:

	* gdbarch.sh (software_single_step): Change return type to
	std::vector<CORE_ADDR>.
	* gdbarch.c, gdbarch.h: Re-generate.
	* arch/arm-get-next-pcs.c (thumb_deal_with_atomic_sequence_raw):
	Adjust.
	(arm_deal_with_atomic_sequence_raw): Adjust.
	(thumb_get_next_pcs_raw): Adjust.
	(arm_get_next_pcs_raw): Adjust.
	(arm_get_next_pcs): Adjust.
	* arch/arm-get-next-pcs.h (arm_get_next_pcs): Adjust.
	* aarch64-tdep.c (aarch64_software_single_step): Adjust.
	* alpha-tdep.c (alpha_deal_with_atomic_sequence): Adjust.
	(alpha_software_single_step): Adjust.
	* alpha-tdep.h (alpha_software_single_step): Adjust.
	* arm-linux-tdep.c (arm_linux_software_single_step): Adjust.
	* arm-tdep.c (arm_software_single_step): Adjust.
	(arm_breakpoint_kind_from_current_state): Adjust.
	* arm-tdep.h (arm_software_single_step): Adjust.
	* breakpoint.c (insert_single_step_breakpoint): Adjust.
	* cris-tdep.c (cris_software_single_step): Adjust.
	* mips-tdep.c (mips_deal_with_atomic_sequence): Adjust.
	(micromips_deal_with_atomic_sequence): Adjust.
	(deal_with_atomic_sequence): Adjust.
	(mips_software_single_step): Adjust.
	* mips-tdep.h (mips_software_single_step): Adjust.
	* moxie-tdep.c (moxie_software_single_step): Adjust.
	* nios2-tdep.c (nios2_software_single_step): Adjust.
	* ppc-tdep.h (ppc_deal_with_atomic_sequence): Adjust.
	* rs6000-aix-tdep.c (rs6000_software_single_step): Adjust.
	* rs6000-tdep.c (ppc_deal_with_atomic_sequence): Adjust.
	* s390-linux-tdep.c (s390_software_single_step): Adjust.
	* sparc-tdep.c (sparc_software_single_step): Adjust.
	* spu-tdep.c (spu_software_single_step): Adjust.
	* tic6x-tdep.c (tic6x_software_single_step): Adjust.

gdb/gdbserver/ChangeLog:

	* linux-arm-low.c (arm_gdbserver_get_next_pcs): Adjust to
	software_single_step change of return type to
	std::vector<CORE_ADDR>.
	* linux-low.c (install_software_single_step_breakpoints):
	Likewise.
	* linux-low.h (install_software_single_step_breakpoints):
	Likewise.
