we use them inside macros.

* Requiring documentation for all public functions is a little too broad
(it covers the auto-gen'ed bindings too, which we don't want). This CL
removes the requirement.
* Minor issues in the hashing implemention using the sha2 crate were
fixed.
* Fixed dependency issues.
* Switch to std::ffi::c_char since this differs by platform.
* Fix clippy errors.

This support doesn't build quite yet, but it's safe to include now
behind a feature. We're planning to set up the build for Perfetto
libraries shortly.

This CL adds a new "root" test suite for trace_marker integration tests,
since the tests require root to run in order to access the kernel's

If the trace_marker feature was enabled but the sysfs file could not be
opened, cros_tracing::push_descriptors() would log an error message each
time it was called. We already log an error when tracing can't be
initialized, so the extra logs aren't necessary and can be removed.

Rather than checking if the trace_marker file in sysfs exists and then
immediately proceeding to open it, we can just try to open it and handle
the resulting error if it doesn't exist.
Additionally, log the filename if the file can't be opened to make the
debugging process easier.

This CL adds a new backend for the cros_tracing crate. This backend can
be enabled by building crosvm with the trace_marker feature enabled.
When the feature is not enabled, no extra overhead incurs as the default
NOOP cros_tracing crate will be compiled in instead.

`tracing` conflicts with a crates.io crate. Since we may support tokio
tracing in the future, and want to submit some benchmarks against it
right now, we should rename our crate.
