Convert macros in elf-linux-core.h to inline functions
Besides changing some macros into inline functions, this removes redundant memsets and uses bfd_put_* rather than H_PUT_*. * elf-linux-core.h (swap_linux_prpsinfo32_out): New function. (swap_linux_prpsinfo64_out): New function. (LINUX_PRPSINFO32_SWAP_FIELDS): Delete. (LINUX_PRPSINFO64_SWAP_FIELDS): Delete. * elf.c (elfcore_write_linux_prpsinfo32): Adjust. Don't memset. (elfcore_write_linux_prpsinfo64): Likewise. * elf32-ppc.c (swap_ppc_linux_prpsinfo32_out): New function. (PPC_LINUX_PRPSINFO32_SWAP_FIELDS): Delete. (elfcore_write_ppc_linux_prpsinfo32): Adjust. Don't memset.
