Subject: [PATCH] xml_utils: explicitly include <stdlib.h>
MIME-Version: 1.0

Building osc in arch linux started to fail because of warnings being
treated as errors:

"
error: implicit declaration of function ‘calloc’ [-Werror=implicit-function-declaration]
  188 |                 text = (char *)calloc(1, sizeof(char)); /* Create an empty string */
      |                                ^~~~~~
note: include ‘<stdlib.h>’ or provide a declaration of ‘calloc’
error: incompatible implicit declaration of built-in function ‘calloc’ [-Werror=builtin-declaration-mismatch]
"

The likely reason is that stdlib.h was somehow being indirectly included
and maybe a change in libxml changed that. Hence, let's just explicitly
include the needed header.
