This CL adds a "tpm" Cargo cfg to crosvm which enables a TPM device
backed by libtpm2 simulator.
Tested by running the following inside cros_sdk:
LIBRARY_PATH=~/src/minijail LD_LIBRARY_PATH=~/src/minijail \
cargo run --release \
--features tpm \

-r rootfs.ext4 \
--seccomp-policy-dir seccomp/x86_64/ \
-p init=/bin/bash \
-p panic=-1 \
--disable-sandbox \
vmlinux.bin
with a Linux image built from CL:1387655.

This change adds the suspend and resume commands to crosvm, as well as
corresponding VmRequest variants and VCPU loop support. When a request
triggers a VmRunMode change, the Mutex guarded shared VmRunMode variable
is mutated and the associated Condvar is notified. Each VCPU thread is
interrupted to kick it out of the KVM_RUN call and checks the VmRunMode,
If the VCPU was already suspended by waiting for the Condvar, the
notify_all call will wake up the thread, upon which the VCPU thread can
respond to the new mode.

This allows manual resizing of block devices at runtime via the command
line ('crosvm disk resize <index> <size>'). The virtio config interrupt
is asserted when the disk size changes so that the guest driver can
update the block device to the updated size.
Currently, there is no automatic policy for resizing disks - that will
be implemented in another change. Additionally, this resize operation
just changes the size of the block device; the filesystem will need to
be resized by the guest (e.g. via the 'btrfs filesystem resize' command)
as a separate step either before (shrinking) or after (expanding) the
disk resize operation.

This CL adds a tpm2-sys crate that builds libtpm2 from source (from a
git submodule) using the existing Makefile and then links the generated
static library as -ltpm2.
For production builds there is a flag `RUSTFLAGS='--cfg hermetic'` to
disallow building our own libtpm2. Instead it will expect to find
libtpm2 installed in the standard system location. Building from the
libtpm2 submodule is a convenience only intended for developer
environments.
The functions exposed by tpm2-sys are the ones that will be necessary to
initialize a TPM simulator in crosvm and execute TPM commands. Trunks
uses the same functions for its simulator mode here:
e4cf13c057/trunks/tpm_simulator_handle.cc
Tested by running:
fn main() {
unsafe {
tpm2_sys::TPM_Manufacture(1);
}
}
inside cros_sdk. Libtpm2 cannot be built outside of cros_sdk because it
requires openssl 1.0.2p, whereas dev machines come with openssl 1.1.0j.
I have not yet added any dependency on tpm2-sys from crosvm, but when it
does get added it will be behind a tpm feature flag so that crosvm can
continue to build outside of cros_sdk just without tpm support.
I published num_cpus version 1.9.0 to chromeos-localmirror.

When minijail is given a uid/gid map but is not given a uid/gid to
change to, it will default to setting the uid/gid inside the new user
namespace to root. This works fine if crosvm is launched as root but
fails miserably otherwise since we only map the current euid/egid into
the user namespace (and so 0 is not a valid uid/gid).
We would normally want to fix this by having minijail change its uid/gid
to the current euid/egid. However, because of the way minijail is set
up it only attempts to enter a new net namespace after exec-ing the
program to be jailed. Entering a new net namespace requires
CAP_SYS_ADMIN in the current namespace and this capability gets dropped
the moment we switch to a non-root user.
So to deal with this we map root inside the namespace to the crosvm user
outside the namespace. This allows us to enter a new net namespace and
we already tell minijail to drop all caps so the plugin will not have
any caps when it actually runs.
