Replace use of our custom, patched libusb APIs with the new
libusb_wrap_sys_device() function, which has been submitted to libusb
upstream. This allows us to drop the bindings for the custom APIs (and
will also allow us to drop the libusb patch that introduces them).
For now, keep this path behind the sandboxed-libusb feature to allow
crosvm to build against older libusb versions that do not have the new
API. This should be cleaned up eventually once we are comfortable with
raising the minimum libusb version required.

When an ill socket is detected, it will be removed from poll_context and
control_sockets, then the remaining good sockets should change their indices,
So modify should be used instead of add, as all of them have been added
into poll_context already, the add will return an error.
This change is merge of another change at
I977be57ea0898cc8226505f7d3da103a46ea626c that was identical to this one
except it contained the following similar commit message:
linux: when renumbering control sockets, use modify instead of add
In some circumstances, a VM control socket will get removed from the
list of control sockets in the run_control loop. Usually, the last
control socket in the list gets removed, but if that is not the case,
the control sockets will get reordered to fill in the gap in the list.
The `add` method of `PollContext` was used to change the token used for
a given control socket, when `modify` should have been used instead.
The problem with using `add` when a control socket is already part of a
`PollContext` is that it will return an error and terminate crosvm. This
CL fixes that issue.

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)
CPU:
DRAM: 16 MiB
unable to get online cpu number: -19
Warning: MP init failure
Model: QEMU x86 (I440FX)
Net: No ethernet found.
error: can't find etc/table-loader
Hit any key to stop autoboot: 0
=>
"""
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.
Bug: b/133358982
Test: ./crosvm_wrapper.sh run --mem=4097 --bios=u-boot.rom

The flag can enable capturing audio from CRAS server to the cras-audio

We'll re-enable capture function on Crostini after finishing capture

Two parts of the documentation mention the generated `fn n`, which (as
of Rust 1.35) causes a doc test failure. Change these code blocks to be
ignored instead of executed to avoid the problem.

The RequestType::Flush handler correctly uses fsync(), which issues an
fsync to the underlying disk image file. However, the flush timer
(started on write and cancelled if a flush request is executed) was only
calling flush(), which is insufficient when the disk image is a raw file
- it just flushes in-memory buffers and does not issue an fsync.
BUG=None
TEST=Issue writes in crosvm; verify fsync in strace output

This makes the PCI root bridge's MMIO range consistent with the
