Bug 1461785 - Update dom/media/mediasource/test to abide eslint rules, add .eslintrc.js. r?jya Add .eslintrc.js to configure globals from mediasource.js and to add extra rules to encourage use of let and const over var. Linting changes: - Prefer const and let to var. This provides tighter scoping and avoids reassignment. - Mozilla rules do not allow for shadowing of variables, so several tests have had promise lists renamed to avoid this. - Numerous minor fixes to formatting including using double quotes, spacing, missing semicolons. - Remove some unused variables. - Fix naming of resourcePathSeen in test_MediaSource_memory_reporting.html.
