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.
