Eric Biggers 3d110c7c6e Fix fwrite() reading beyond end of buffer in error path
Partially revert commits 2b766585f9 and
de2fd463b1, which were intended to fix BZ#11741
but caused another, likely worse bug, namely that fwrite() and fputs() could,
in an error path, read data beyond the end of the specified buffer, and
potentially even write this data to the file.

Fix BZ#11741 properly by checking the return value from _IO_padn() in
stdio-common/vfprintf.c.
