trace-cmd: Replace time sync protocol ID with string
Different timestamp synchronization algorithms will be implemented as
trace-cmd plugins. Using IDs for identifying these algorithms is
a problem, as these IDs must be defined in a single place. In order
to be more flexible, protocol IDs are replaced by protocol names -
strings that are part of the plugin code and are registered with
plugin initialisation.
The plugin names are limited up to 15 symbols, in order to simplify
the structure of sync messages.
