Add kvm_<sycall> wrappers for munmap(), close(), fallocate(), and ftruncate() to cut down on boilerplate code when a sycall is expected to succeed, and to make it easier for developers to remember to assert success. Implement and use a macro framework similar to the kernel's SYSCALL_DEFINE infrastructure to further cut down on boilerplate code, and to drastically reduce the probability of typos as the kernel's syscall definitions can be copy+paste almost verbatim. Provide macros to build the raw <sycall>() wrappers as well, e.g. to replace hand-coded wrappers (NUMA) or pure open-coded calls.
