Removed casts from ngx_memcmp() macro.
Casts are believed to be not needed, since memcmp() has "const void *"
arguments since introduction of the "void" type in C89. And on pre-C89
platforms nginx is unlikely to compile without warnings anyway, as there
are no casts in memcpy() and memmove() calls.
These casts were added in 1648:89a47f19b9ec without any details on why they
were added, and Igor does not remember details either. The most plausible
explanation is that they were copied from ngx_strcmp() and were not really
needed even at that time.
