misc/bits/select2.h: Clearly separate declaration from definitions
The __fdelt_chk declaration needs to be available so that libc_hidden_proto can be used while not redefining __FD_ELT. Thus, misc/bits/select-decl.h is created to hold the corresponding prototypes. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
