MFC r315701 (by ed):
Set the interpreter path to /nonexistent.
MFC r315749:
Adjust r314851 to not require every brand to specify interpreter path.
MFC r315753:
Add a flag BI_BRAND_ONLY_STATIC to specify that the brand only
matches static binaries.
MFC r315754:
Update r315753 with the proper flag name.
MFC r316211:
A followup to r315749, two more places where brand->interp_path was
accessed unconditionally.

MFC r312353, r312354 and r312355:
Sync in the latest CloudABI generated source files.
Languages like C++17 and Go provide direct support for slice types:
pointer/length pairs. The CloudABI generator now has more complete for
this, meaning that for the C binding, pointer/length pairs now use an
automatic naming scheme of ${name} and ${name}_len.
Apart from this change and some reformatting, the ABI definitions are
identical. Binary compatibility is preserved entirely.
MFC r315700:
Make file descriptor passing work for CloudABI's sendmsg().
Reduce the potential amount of code duplication between cloudabi32 and
cloudabi64 by creating a cloudabi_sock_recv() utility function. The
cloudabi32 and cloudabi64 modules will then only contain code to convert
the iovecs to the native pointer size.
In cloudabi_sock_recv(), we can now construct an SCM_RIGHTS cmsghdr in
an mbuf and pass that on to kern_sendit().
MFC r315736:
Make file descriptor passing for CloudABI's recvmsg() work.
Similar to the change for sendmsg(), create a pointer size independent
implementation of recvmsg() and let cloudabi32 and cloudabi64 call into
it. In case userspace requests one or more file descriptors, call
kern_recvit() in such a way that we get the control message headers in
an mbuf. Iterate over all of the headers and copy the file descriptors
to userspace.

Stop providing the compat_3_brand.
As of r315860, the ELF image activator works fine for CloudABI without it.

r304991, r305928, r305938, r305987, r306185:
Bring CloudABI support back in sync with HEAD.
- Add support for running 32-bit executables on amd64, armv6 and i386.
- As these new architectures require the use of the vDSO, merge back
vDSO support for 64-bit executables running on amd64 and arm64 as
well. This has the advantage that support for vDSO-less execution
can be phased out when 11.0 becomes unsupported, as opposed to 11.x.
This change has been tested by running the cloudlibc unit tests on all
supported architectures, which seems to work fine.
