We leave IPPROTO_MAX as is for the time being. However, in recent
kernel releases IPPROTO_MAX is actually higher and reflects the
addition of IPPROTO_MPTCP.

From sys/uio.h. Note that preadv64/pwritev64 are already included in
src/unix/linux_like/mod.rs.
Also fix parameter names of process_vm_[readv,writev] to match Bionic
header.

On sparc-unknown-linux-gnu, char is signed, not unsigned.

Support was previously added to gnu x86_64 and all musl targets but
others were not included because of a roundtrip issue [1].

This commit adds support for the ip_mreqn struct on all Linux GNU
targets which did not have the roundtrip issue.

Move the link line for `libdl` up to `src/unix/mod.rs`, making it easier
to see all the libraries `libc` links to.

This also makes `libdl` respect `target-feature=+crt-static`.

The two library blocks that specify `#[link(name = "util")]` do not
actually reference any functions in `libutil`; the functions that do use
`libutil` don't have any reference to it. And having two library blocks
specify it results in two separate inclusions of `-lutil` on the linker
command line. Move the link lines up to `src/unix/mod.rs`, making it
easier to see all the libraries `libc` links to.

This also makes `libutil` respect `target-feature=+crt-static`.
