commit 18855b8979e6c7e14ab2a49132e6e5b9e94ed685

    raster: make rtstrdup return NULL on allocation failure like strdup
    
    Standard strdup returns NULL when it cannot allocate memory for the
    copy; rtstrdup instead unconditionally memcpy'd into the rtalloc result,
    writing through a NULL pointer when the allocation failed. Guard the
    copy behind the allocation check so rtstrdup returns NULL on out of
    memory, mirroring the standard library semantics its name implies.
