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.)
