Subzero: Allow overriding command-line args from the browser.
In the browser build only, allows arguments to be explicitly passed to pnacl-sz, in two ways:
1. The SZARGFILE envvar contains the name of a file with arguments, one per line. For each line, initial whitespace is ignored, and lines starting with the '#' comment character are also ignored.
2. The SZARGLIST envvar contains all the arguments, separated by the '|' character.
Chrome needs to be started with special options to allow the envvars to be passed through, and also to allow access to the local file system.
In addition, specifying "-log=/dev/stderr" or "-o /dev/stderr" gets mapped to std::cerr, in the same way "-" gets mapped to std::cout.
