aarzilli 7555d1c063 cmd,proc,terminal,debugger: Support default file descriptor redirects 
Adds features to support default file descriptor redirects for the
target process:

1. A new command line flag '--redirect' and '-r' are added to specify
   file redirects for the target process
2. New syntax is added to the 'restart' command to specify file
   redirects.
3. Interactive instances will check if stdin/stdout and stderr are
   terminals and print a helpful error message if they aren't.

dlv trace

Compile and begin tracing program.

Synopsis

Trace program execution.

The trace sub command will set a tracepoint on every function matching the provided regular expression and output information when tracepoint is hit. This is useful if you do not want to begin an entire debug session, but merely want to know what functions your process is executing.

The output of the trace sub command is printed to stderr, so if you would like to only see the output of the trace operations you can redirect stdout.
