libio: Eliminate _IO_stdin, _IO_stdout, _IO_stderr
These variables are only used to determine if a stdio stream is a pre-allocated stream, but it is possible to do so by comparing a FILE * to all pre-allocated stream objects. As a result, it is not necessary to keep those pointers in separate variables. Behavior with symbol interposition is unchanged because _IO_stdin_, _IO_stdout_, _IO_stderr_ are exported, and refer to objects outside of libc if symbol interposition or copy relocations are involved. (The removed variables _IO_stdin, _IO_stdout, _IO_stderr were not exported, of course.)
