struct_value_regnum.
(m68k_svr4_init_abi): New prototype.
* m68k-tdep.c: Include "floatformat.h".  Add comment about all the
different calling conventions.
(m68k_extract_return_value): Remove code dealing with single-field
structs.
(m68k_store_return_value): Remove code dealing with single-field
structs.  Correctly store return values of 5, 6, 7 or 8 bytes.
(m68k_extract_struct_value_address): Remove function.
(m68k_svr4_extract_return_value,m68k_svr4_store_return_value)
(m68k_reg_struct_return_p, m68k_return_value)
(m68k_svr4_return_value): New functions.
(m68k_use_struct_convention): Remove function.
(m68k_push_dummy_call): Use new struct_value_regnum member of
`struct gdbarch_tdep' instead of hardcoded register number to
store STRUCT_ADDR.
(m68k_svr4_init_abi): New function.
(m68k_gdbarch_init): Don't set extract_return_value,
store_return_values, deprecated_extract_struct_value_address and
use_struct_convention.  Set return_value instead.  Initialize new
struct_value_regnum member of `struct gdbarch_tdep'.
* m68klinux-tdep.c: Update copyright year.
(m68k_linux_extract_return_value, m68k_linux_store_return_value)
(m68k_linux_extract_struct_value_address): Remove function.
(m68k_linux_init_abi): Don't set extract_return_value,
store_return_values, deprecated_extract_struct_value_address and
use_struct_convention.  Call m68k_svr4_init_abi but override the
new struct_value_regnum member of `struct gdbarch_tdep'.
* Makefile.in (m68k-tdep.o): Update dependencies.
