tracing: Add DYNAMIC flag for dynamic events
To differentiate between static and dynamic events, add a new flag DYNAMIC to the event flags that all dynamic events have set. This will allow to differentiate when attaching to a dynamic event from a static event.
Static events have a mod pointer that references the module they were created in (or NULL for core kernel). This can be incremented when the event has something attached to it. But there exists no such mechanism for dynamic events. This is dangerous as the dynamic events may now disappear without the "attachment" knowing that it no longer exists.
To enforce the dynamic flag, change dyn_event_add() to pass the event that is being created such that it can set the DYNAMIC flag of the event. This helps make sure that no location that creates a dynamic event misses setting this flag.

It's kind of strange to have check_arg() callbacks as part of the arg objects themselves; it makes more sense to just pass these in when the args are added instead.
Remove the check_arg() callbacks from those objects which also means removing the check_arg() args from the init functions, adding them to the add functions and fixing up existing callers.

tracing: Add dynamic event command creation interface
Add an interface used to build up dynamic event creation commands, such as synthetic and kprobe events. Interfaces specific to those particular types of events and others can be built on top of this interface.
Command creation is started by first using the dynevent_cmd_init() function to initialize the dynevent_cmd object. Following that, args are appended and optionally checked by the dynevent_arg_add() and dynevent_arg_pair_add() functions, which use objects representing arguments and pairs of arguments, initialized respectively by dynevent_arg_init() and dynevent_arg_pair_init(). Finally, once all args have been successfully added, the command is finalized and actually created using dynevent_create().
The code here for actually printing into the dyn_event->cmd buffer using snprintf() etc was adapted from v4 of Masami's 'tracing/boot: Add synthetic event support' patch.
