libc headers: make `<complex.h>` work, add `struct ipv6_mreq` (#1100) 1. `libc/isystem/complex.h` (included when you do `#include <complex.h>`) defines `_COMPLEX_H`, and then proceeds to include `libc/complex.h`, which contains the actual complex-related declarations. However, they are also guarded by `_COMPLEX_H` and hence effectively ignored. Fix this by changing `_COMPLEX_H` to `COSMOPOLITAN_LIBC_COMPLEX_H_`, which is consistent with what the other headers (such as `math.h`) do. 2. Cosmopolitan could only support IPv4 multicast requests for sockets, since a declaration for `struct ipv6_mreq` was missing. Add support for IPv6, too, by adding the missing declaration. 2024-02-05 23:22:56 +01:00			`#ifndef COSMOPOLITAN_LIBC_SOCK_STRUCT_IPV6_MREQ_H_`
