coredump: move dump_write() and dump_seek() into a header file My next patch will replace ELF_CORE_EXTRA_* macros by functions, putting them into other newly created .c files. Then, each files will contain dump_write(), where each pair of binfmt_.c and elfcore.c should be the same. So, this patch moves them into a header file with dump_seek(). Also, the patch deletes confusing DUMP_WRITE macros in each files.

Un-inline the core-dump helper functions Tony Luck reports that the addition of the access_ok() check in commit 0eead9ab41da ("Don't dump task struct in a.out core-dumps") broke the ia64 compile due to missing the necessary header file includes. Rather than add yet another include (<asm/unistd.h>) to make everything happy, just uninline the silly core dump helper functions and move the bodies to fs/exec.c where they make a lot more sense. dump_seek() in particular was too big to be an inline function anyway, and none of them are in any way performance-critical. And we really don't need to mess up our include file headers more than they already are.
