cinap_lenrek 6d42467411 stdio: fix sclose() buffer overrun when terminating string, realloc() error handling (thanks porlock) 
theres a bug is in sclose() where it doesnt check if wp is beyond
the buffer. also wp was not updated after realloc().

bug was reported by porlock on 9fans:

Plan 9's implementation of the standard C functions snprintf and
vsnprintf have a buffer overrun bug.

If the buffer length equals the output length (without the terminating
null), then one too many characters is written to the buffer.

For example,
              snprintf(buf, 4, "ABCD");

will write 5 characters to buf.
