Make __sdidinit unused
...
Remove dependency on __sdidinit member of struct _reent to check
object initialization. Like __sdidinit, the __cleanup member of
struct _reent is initialized in the __sinit() function. Checking
initialization against __cleanup serves the same purpose and will
reduce overhead in the __sfp() function in a follow up patch.

Update setvbuf to latest OpenBSD implementation
...
Newlib's setvbuf function is very old and has two bugs:
- It sets the SRD/SWR flags incorrectly in case of files opened for
reading and writing.
See https://cygwin.com/ml/cygwin/2016-03/msg00180.html
for a desription of the effect.
- It always sets the buffer size to BUFSIZ if it's not provided by
the application, independent of the optimal blocksize for the
underlying IO device.
Update setvbuf to latest code from OpenBSD to fix both problems.
* libc/stdio/setvbuf.c (setvbuf): Import latest OpenBSD
implementation.
