The component updater in Chrome is responsible for updating code and data
modules such as Flash, CrlSet, Origin Trials, etc. These modules are updated on
cycles independent of the Chrome release tracks.
It runs in the browser process and communicates with a set of servers
using the Omaha protocol to find the latest versions of components, download
them, and register them with the rest of Chrome.
