There is no longer a need for string2.h, so remove it and all mention of it. Move the redirect for __stpcpy to include/string.h since it is still required until all internal uses have been renamed. This fixes several linknamespace/localplt failures when building with -Os. [BZ #15105] [BZ #19463] * include/string.h: Add internal redirect for __stpcpy. * string/Makefile: Remove bits/string2.h. * string/string.h: Update comment. * string/string-inlines.c: Remove bits/string2.h include and comment. * string/bits/string2.h: Remove file.
