The old Linux baseline was essentially RHEL 6 but that distro has been
out of support for two years now. Move to RHEL 7.
This commit also moves FreeBSD to tier 2 because it isn't actually
part of libuv's CI matrix, only Node's.

The GNU/Hurd platform does not define IP_ADD_SOURCE_MEMBERSHIP,
IP_DROP_SOURCE_MEMBERSHIP, MCAST_JOIN_SOURCE_GROUP and
MCAST_LEAVE_SOURCE_GROUP.
Implement a few functions for the GNU/Hurd. Specifically:
* uv_resident_set_memory (from Linux)
* uv_get_free_memory (from Linux)
* uv_get_total_memory (from Linux)
* uv_cpu_info (from cygwin)
* uv__process_title_cleanup (void)
* uv_get_constrained_memory (stub)
* Leave proctitle unimplemented on Hurd for now
* Implement hurdish uv_exepath
* Enable ifaddrs api
* Unbreak udp basics
* Unbreak futime and lutime on Hurd
With MUSL libc, the struct msghdr is padded to align with the types used
in the Linux kernel headers (int vs size_t). When the padding was not
zeroed, the syscall would return EMSGSIZE because the random bytes in
the padding would be read by kernel as part of the size_t type.

sendmmsg returns with number of packets sent which can
be less than number of packets requested to be sent. Do
not flush entire write queue and use the returned info

The Linux kernel suppresses some ICMP error messages by default for UDP
sockets. This commit sets IP_RECVERR/IPV6_RECVERR on the socket to
enable full ICMP error reporting, hopefully resulting in faster failover
to working name servers.

Android/i386 doesn't have separate sendmmsg/recvmmsg system calls,
they're multiplexed through the socketcall system call.
(More precisely, the system calls may be present but the standard
seccomp filter rejects them, whereas socketcall is whitelisted.)
This commit removes the flags and timeout arguments from libuv's
internal system call wrappers because they're always zero and it
makes EINVAL/ENOSYS detection after a failed socketcall() easier.

Update this code to be more in line with the Windows version.
Previously, callers (such as nodejs) might assume it was always safe to de-reference this parameter:
d2634be562/src/tcp_wrap.cc (L349) called from d2634be562/src/udp_wrap.cc (L567)
I suspect this may have been unreachable, and that it was guaranteed by the kernel to be `>= sizeof(struct sockaddr)`, so this should be a NFC simplification.
