console: Add a console buffer
It is useful to be able to record console output and provide console input via a buffer. This provides sandbox with the ability to run a command and check its output. If the console is set to silent then no visible output is generated. This also provides a means to fix the problem where tests produce unwanted output, such as errors or warnings. This can be confusing. We can instead set the console to silent and record this output. It can be checked later in the test if required. It is possible that this may prove useful for non-test situations. For example the console output may be suppressed for normal operations, but recorded and stored for access by the OS. That feature is not implemented at present. Signed-off-by: Simon Glass <sjg@chromium.org>
