scanner: Fix for memleak due to unclosed file pointer
When including a file, it is opened by fopen() and therefore needs to be
closed after scanning has finished using fclose(), otherwise valgrind
will report a memleak.
This patch changes struct input_descriptor to track the opened FILE
pointer instead of the file descriptor so the pointer is available for
closing in scanner_destroy().
While at it, change erec_print() to work on the open FILE pointer so it
doesn't have to call fileno() in beforehand. And as a little bonus, use
C99 initializer of the buffer to get rid of the call to memset().
Note that it is necessary to call erec_print_list() prior to destroying
the scanner, otherwise it will start manipulating an already freed FILE
pointer (and therefore crash the program).
