stralloc_catm - append string(s) to a stralloc

       stralloc_catm  appends  \0-terminated strings from s... to the end of the string stored in sa, allocating
       space if necessary, and returns 1. If sa is unallocated, stralloc_catm is the same as stralloc_copym.

       If it runs out of memory, stralloc_catm returns 0.  At that point, it may already have copied  a  few  of
       the strings to sa.
