b5920069c7 Support command line arguments. 
It's now possible to set the environment variables with an argument. The
env var will be overridden. For instance to start
hello on an UHyve isle: `proxy run ./hello --isle uhyve -d`

937d064450 Fixed missing path in Uhyve 
A missing path due to the isle kind shouldn't be treated as an error.
Add the clap library to support commands.

abbcee0b46 Replace the Isle variant with a proper Trait. 
The proxy library was moved into an own directory. Then the IsleKind
enum was replaced with an Isle trait which is implemented by
qemu/multi/uhyve.

ee1682fa1a Set the memsz in the kernel header correctly 
The protocol structs should be packed. uHyve works now in single core
mode.

bb0e1f2a36 Improved error handling 
The error::Error enum has changed to provide additional information,
especially about missing files and failed IOCTL commands.

d687208b01 Use of intended ioctl! syntax 
The syntax ioctl!(write <fnc> with KVMIO, <id>; <type>) is shorter than
ioctl!(<fnc> with iow!(KVMIO, <id>; mem::size_of::<type>())). Futhermore
the filedescriptor of vcpu.rs was invalid, because the destructor of
File::from_raw was immediately called. The vcpu struct contains now
the copy of the fd in the Rust world, perhaps there is an easier way to
pass the fd to memmap.

5226d4a19a The first isle is usable. This commit exists to check in a heavily WIP 
version of the HermitCore proxy, rewritten in Rust. Any attempt to use
the current version in a serious manner should be avoided. The Multi and
UHyve isles aren't tested yet.

4851d8461a add proof of concept to create checkpoints 
- HERMIT_CHECKPOINT=x defines the period x (in seconds) to create
  checkpoints
- by starting of an HermitCore application, uhyve checks
  if an checkpoint is avaiable in the subdirectory
  "checkpoint"
- uhyve starts the application from the latest checkpoint
