[PATCH] A grab bag of trivial things.

During porting I found a couple of things in the source, like slightly wrong types (int vs. LogLevel), a leaking field and calls c-library functions where x-functions exist (xrecallocarray, xasprintf).

Also includes for xmss which I think should be wrapped in #ifdef.

The patch is attached.
