coredump,basic: generalize O_TMPFILE handling a bit
This moves the O_TMPFILE handling from the coredumping code into common library code, and generalizes it as open_tmpfile_linkable() + link_tmpfile(). The existing open_tmpfile() function (which creates an unlinked temporary file that cannot be linked into the fs) is renamed to open_tmpfile_unlinkable(), to make the distinction clear. Thus, code may now choose between: a) open_tmpfile_linkable() + link_tmpfile() b) open_tmpfile_unlinkable() Depending on whether they want a file that may be linked back into the fs later on or not. In a later commit we should probably convert fopen_temporary() to make use of open_tmpfile_linkable(). Followup for: #3065
