Apply asm redirections in stdio.h before first use [BZ #27087]
Compilers may not be able to apply asm redirections to functions after these functions are used for the first time, e.g. clang 13. Fix [BZ #27087] by applying all long double-related asm redirections before using functions in bits/stdio.h. However, as these asm redirections depend on the declarations provided by libio/bits/stdio2.h, this header was split in 2: - libio/bits/stdio2-decl.h contains all function declarations; - libio/bits/stdio2.h remains with the remaining contents, including redirections. This also adds the access attribute to __vsnprintf_chk that was missing. Tested with build-many-glibcs.py. Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com>
