- Sometimes we need customized cmd to get serial log, ex FTDI4232H
chip gets serial log through usb directly, thus we need to call
cmd like `pyterm.py ftdi://ftdi:4232:FT7JLD0U/1`.
- There are seveval places in console implementation to call
osutil.Command, move the command code into one function.

They are shorter, more readable, and don't require temp vars.

The current code is now broken on darwin:
syzkaller$ GOOS=darwin go install ./vm/...
vm/vmimpl/console.go:30:33: undefined: unix.SYS_IOCTL
vm/vmimpl/console.go:45:32: undefined: unix.SYS_IOCTL

Fix capitalization, dots at the end
and two spaces after a period.

A good one. Lots of fixed comments are contributed by episodic contributors.
So it's good to catch these earlier.

Underscores are against Go coding style.

Not sure why I have not seen warnings about
these lines on another machine...

When manager is stopped there are sometimes runaway qemu
processes still running. Set PDEATHSIG for all subprocesses.
We never need child processes outliving parents.

Add a new isolated VM for machines that you cannot easily manage. It
assumes the machine is only available through SSH and create a reverse
proxy to ensure the machine can connect back to syz-manager.

VM infrastructure currently has several problems:
- Config struct is complete mess with a superset of params for all VM types
- verification of Config is mess spread across several places
- there is no place where VM code could do global initialization
like creating GCE connection, uploading GCE image to GCS,
matching adb devices with consoles, etc
- it hard to add private VM implementations
such impl would need to add code to config package
which would lead to constant merge conflicts
- interface for VM implementation is mixed with interface for VM users
this does not allow to provide best interface for both of them
- there is no way to add common code for all VM implementations
This change solves these problems by:
- splitting VM interface for users (vm package) and VM interface
for VM implementations (vmimpl pacakge), this in turn allows
to add common code
- adding Pool concept that allows to do global initialization
and config checking at the right time
- decoupling manager config from VM-specific config
each VM type now defines own config
Note: manager configs need to be changed after this change:
VM-specific parts are moved to own "vm" subobject.
Note: this change also drops "local" VM type.
Its story was long unclear and there is now syz-stress which solves the same problem.
