* A helper function parsing provided command line arguments and handling two
* specific args:
*
* -MOZ_LOG=modulelist
* -MOZ_LOG_FILE=file/path
*
* both expecting an argument, and corresponding to the same-name environment
* variables we use for logging setup.
*
* When an argument is found in the proper form, the consumer callback is called
* with a string in a follwing form, note that we do this for every occurence,
* and not just at the end of the parsing:
*
* "MOZ_LOG=modulelist" or "MOZ_LOG_FILE=file/path"
*
* All the following forms of arguments of the application are possible:
*
* --MOZ_LOG modulelist
* -MOZ_LOG modulelist
* --MOZ_LOG=modulelist
* -MOZ_LOG=modulelist
*
* The motivation for a separte function and not implementing a command line
* handler interface is that we need to process this very early during the
* application startup. Command line handlers are proccessed way later
* after logging has already been set up.
