Add fz_malloc_struct, and make code use it.

The new fz_malloc_struct(A,B) macro allocates sizeof(B) bytes using
fz_malloc, and then passes the resultant pointer to Memento_label
to label it with "B".

This costs nothing in non-memento builds, but gives much nicer
listings of leaked blocks when memento is enabled.
