The --redirect-warnings command line argument allows process warnings
to be written to a specified file rather than printed to stderr.

Also adds an equivalent NODE_REDIRECT_WARNINGS environment variable.

If the specified file cannot be opened or written to for any reason,
the argument is ignored and the warning is printed to stderr.

If the file already exists, it will be appended to.

Mutations of the environment can invalidate pointers to environment
variables, so make `secure_getenv()` copy them out instead of returning
pointers.

This is the part of nodejs#11051 that
applies to be11fb4.
This part wasn't backported to 6.x when nodejs#11051 was backported
because the semver-minor introduction
of NODE_REDIRECT_WARNINGS hadn't been backported yet. Now that the
env var is backported, this last bit of nodejs#11051 is needed.

A dynamically allocated array was being used, simplify the memory
management by using std::vector.

Not all CLI options are supported, those that are problematic from a
security or implementation point of view are disallowed, as are ones
that are inappropriate (for example, -e, -p, --i), or that only make
sense when changed with code changes (such as options that change the
javascript syntax or add new APIs).

When test-cli-node-options is run it uses the --trace-events-enabled
option which generates a file named node_trace.1.log. This commit
changes the working directory to the test tmp directory to avoid this
file being created in the project root.
