Add Makefiles for CloudABI kernel modules. Place all of the machine/pointer size independent code in a kernel module called 'cloudabi'. All of the 64-bit specific code goes in a separate module called 'cloudabi64'. The latter is only enabled on amd64, as it is the only architecture supported.

# $FreeBSD$
Provide the CloudABI vDSO to its executables. CloudABI executables already provide support for passing in vDSOs. This functionality is used by the emulator for OS X to inject system call handlers. On FreeBSD, we could use it to optimize calls to gettimeofday(), etc. Though I don't have any plans to optimize any system calls right now, let's go ahead and already pass in a vDSO. This will allow us to simplify the executables, as the traditional "syscall" shims can be removed entirely. It also means that we gain more flexibility with regards to adding and removing system calls. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D7438

Refactoring: move out generic bits from cloudabi64_sysvec.c. In order to make it easier to support CloudABI on ARM64, move out all of the bits from the AMD64 cloudabi_sysvec.c into a new file cloudabi_module.c that would otherwise remain identical. This reduces the AMD64 specific code to just ~160 lines. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D3974
