* scripts/abilist.awk: If variable `parse_names' is set, grok the file

Browse Source 
header lines and write out foo.symlist files for each foo.so.NN listed.

	* libio/libioP.h (_IO_wfile_jumps): Remove attribute_hidden.
	This symbol is exported, and we don't want to hide it.
	Add libc_hidden_proto instead.
	(_IO_file_jumps): Add libc_hidden_proto.
	* libio/wfileops.c (_IO_wfile_jumps): Add libc_hidden_data_def.
	Remove INTVARDEF.
	* libio/fileops.c (_IO_file_jumps): Likewise.
	* libio/stdfiles.c: Don't use INTUSE on them.
	* libio/iofdopen.c (_IO_new_fdopen): Likewise.
	* libio/iofopen.c (__fopen_internal): Likewise.
	* libio/freopen.c (freopen): Likewise.
	* libio/freopen64.c (freopen64): Likewise.
	* libio/iovdprintf.c (_IO_vdprintf): Likewise.
