/*
xmalloc - a safe malloc
Use this function instead of malloc whenever you don't intend to check
the return value yourself, for instance because you don't have a good
way to handle a zero return value.
Typically, Wine's own memory requests should be handled by this function,
while the clients should use malloc directly (and Wine should return an
error to the client if allocation fails).
