* travis: update CI environments * Add BlueSocketTestCommonLibrary, BlueSocketTestClient, BlueSocketTestServer - Add a library component to make it easier to do tests and profiling under streaming loads (multiple client connections, lots of data, etc.) * Removed Swift 4.x, bumped minimum swift version requirement to 5.1 * keep build at Swift 5.0; update CI to only test from 5.1.5 on up * Only attempt to build command-line for Swift 5.2+ * Ensure tools and dependencies only build for Swift 5.2+ * Address various lint errors * Update README with version details and latest iOS related issues
