Before this change, setting console=true on a serial port caused that
port to be the one connected to the crosvm process' standard input. By
adding an extra 'stdin' argument to the serial parameters it's
possible to make those concepts independent.
Just as with the console argument, stdin defaults to serial port
1 (ttyS0) when not provided and it's possible to set no serial port
connected to stdin (or set as the console) by defining the first
serial port without the stdin (console) argument.

This manifested itself in a couple places that were turning shared
memory buffers into slices for the purposes of passing these slices to
`Read` and `Write` trait methods.
However, this required the removal of the methods that took `Read` and
`Write` instances. This was a convenient interface but impossible to
implement safely because making slices from raw pointers without
enforcing safety guarantees causes undefined behaviour in Rust. It turns
out lots of code in crosvm was using these interfaces indirectly, which
explains why this CL touches so much.

The --bios argument is added as an alternative to the kernel positional
argument. The BIOS runs in unreal mode (16-bit cs selector set to the
end of 32-bit address space), which matches the default state KVM puts
the segment and data registers into.
Example usage:
Build u-boot with "make qemu-x86_defconfig && make"
Run crosvm with "crosvm_wrapper.sh run --bios=u-boot.rom"
This produces the following message:
"""
U-Boot 2019.01-00017-gdc76aabe6a-dirty (May 21 2019 - 12:17:02 -0700)

At this point the u-boot shell works with stdin/stdout, but virtual
disks passed with --rwdisk weren't immediately visible from running
"virtio scan" and "virtio info".
This change puts the bios loading together with the linux kernel loading
code since there is a lot of overlap in functionality.

AddressAllocator now maintains a HashMap<Alloc, (u64, u64, u64)>,
which uniquely maps a Allocation enum (e.g: PciBar(bus, dev, bar),
GpuRenderNode, etc...) to it's address, size, and human-readable tag
/ description.
The interface has also been modified to use Error instead of Option.
Aside from improving debugging, tracking allocations will have
numerous uses in the future. For example, when allocating guest memory
over VmControl sockets, it will be possible to restrict allocations to
pre-allocated slices of memory owned by the requesting device.
To plumb through PCI information to PCI devices, this CL necessitated
the addition of a PciDevice method called `assign_bus_dev`, which
notifies PCI devices of their uniquely assigned Bus and Device numbers.

In Rust 2018 edition, `extern crate` is no longer required for importing

use dep::Thing;
we write:

In this approach, macros are imported individually from the declaring
crate rather than through #[macro_use]. Before:
#[macro_use]
extern crate sys_util;
After:
use sys_util::{debug, error};
The only place that `extern crate` continues to be required is in

Avoiding Box<dyn Error> makes it less likely that we display errors with
insufficient context by accident.
Many of the errors touched in this CL already had helpful message
written! But those corresponding enum variants were never being
instantiated, and that bug was masked by Box<dyn Error>. For example see
the Error::LoadCmdline and Error::LoadKernel.
pub enum Error {
LoadCmdline(kernel_loader::Error),
...
}
Before this CL:
// Bug: boxes the underlying error without adding LoadCmdline
kernel_loader::load_cmdline(...)?;
After this CL:
kernel_loader::load_cmdline(...).map_err(Error::LoadCmdline)?;

I have been running into Debug-printed error messages too often and
needing to look up in the source code each level of nested errors to
find out from the comment on the error variant what the short name of
the variant means in human terms. Worse, many errors (like the one shown
below) already had error strings written but were being printed from the
calling code in the less helpful Debug representation anyway.
Before:
[ERROR:src/main.rs:705] The architecture failed to build the vm: NoVarEmpty
After:
[ERROR:src/main.rs:705] The architecture failed to build the vm: /var/empty doesn't exist, can't jail devices.

Each device (Bus, Pci, Proxy, etc), gets a debug label associated with
it. When a child is spawned, the debug label for it is stored in
a map with the child's pid as the key. If a SIGCHLD is handled, this map
is used to print a more helpful message about exactly which child died.
BUG=None
