Add new ways to manage serial devices

Browse source 
* Rename --list-devices to --list

 * Rename --no-autoconnect to --no-reconnect

 * Switch -l and -L options

   * -l now lists available serial devices

   * -L enables log to file

 * Add option --auto-connect <strategy>

   * Supported strategies:

     * "new" - Waits to connect first new appearing serial device

     * "latest" - Connects to latest registered serial device

     * "direct" - Connect directly to specified serial device (default)

 * Add options to exclude serial devices from auto connect strategy by
   pattern

   * Supported exclude options:

     * --exclude-devices <pattern>

       Example: '--exclude-devices "/dev/ttyUSB2,/dev/ttyS?"'

     * --exclude-drivers <pattern>

       Example: '--exclude-drivers "cdc_acm"'

     * --exclude-tids <pattern>

       Example: '--exclude-tids "yW07,bCC2"'

     * Patterns support '*' and '?'

 * Connect to same port/device combination via unique topology ID (TID)

   * Topology ID is a 4 digit base62 encoded hash of a device topology
     string coming from the Linux kernel. This means that whenever you
     plug in the same e.g. USB serial port device to the same USB hub
     port connected via the exact same hub topology all the way to your
     computer, you will get the same unique TID.

   * Useful for stable reconnections when serial device has no serial
     device by ID

   * For now, only tested on Linux.

 * Reworked and improved listing of serial devices to show serial devices:

   * By device

     * Including TID, uptime, driver, and description.

     * Sorted by uptime (newest device listed last)

   * By unique topology ID

   * By ID

   * By path

 * Add script interface 'list = tty_search()' for searching for serial
   devices.
