decrypt to file

When compiled with -O2 optimisations, decrypting to a, currently non-existent, file (and possibly a directory) fails with a segmentation fault.

This is caused by a null pointer dereference at io.c:186, called from cli.c:82.

Using fewer or no optimisations (-O1 or -O0) or having the file already exist do not cause this error to occur.

Identified the cause as a combination of the following:

decrypt.c:118
- sets output to NULL
cli.c:82
- calls io_is_stdout with NULL output
io.h:108
- attribute declares that function parameter will not be NULL

Hence: the NULL check is removed from the function with optimisations -O2 and higher.

A fix is on the way :-)
