Consolidate most CommandLine code across platforms.

Significant refactoring with some notable behavior changes:
1. Switches are appended preceding existing arguments (after other swtiches).
2. (Windows) command_line_string() is generated and properly quoted/escaped.
3. Appended switches will retain their (optional) included prefixes (--,-,/).
Notable internal changes (shouldn't affect behavior):
1. (Windows) Generate the cl string, instead of storing&updating the original.
2. Explicitly retain switch prefixes (--,-,/) (was automatic in init*/ctor).
Update (obvious) code expecting switches to be appended antecedent to args.
Add Nico's test from: codereview.chromium.org/6728016/.

An intermediary CL landed between patch set 3 and 4, see:
