6b19695c81 Add "base" crate and transition crosvm usages to it from sys_util
For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

85abeff27f vfio: Implement bar mappable
if device bar is mappable, map bar's gpa to hpa in EPT, guest vcpu
could access this bar directly through EPT without trapping. This
could improve performance.

vm.add_mmio_memory could help do this, here vfio_pci send
RegisterMmapMemory request through vm_control socket to do this.

04a82c7be1 devices: vfio: fix clippy warnings
Fix boxed_local, const_static_lifetime, useless_format, and
redundant_closure clippy warnings in the VFIO code.

This fixes all clippy warnings except a single instance of
let_and_return in VfioPciDevice::keep_fds(), since that code is modified
in an upcoming patch.
