Implement the LTTng probe callbacks. One notable file here is
lttng-events.h, which is the core implementation of the LTTng
TRACE_EVENT macros for generation of probes and tracepoint decription
from the TRACE_EVENT declarations.

Add the "lttng" virtual file to debugfs and procfs. All operations are
performed through ioctls (LTTng ioctl range is already reserved
upstream) on this virtual file and on anonymous file descriptors
returned by these ioctls. Each file descriptor is associated with a
tracer "object" (session, channel, stream, event, context).

Modifications to the in-kernel TRACE_EVENT are needed to generate the
compact event descriptions and the probe code LTTng generates. These
changes could apply to upstream TRACE_EVENT, but requires changing the
in-kernel API.

1. No need to check if a list is empty before list_for_each_ looping as
this is already checked by loop stopping conditional.

The side effect is reduced indentation depth
from:
	if (!list_empty)
		list_for_each()
to:
	list_for_each()

2. drop cb_ prefix from cl_pos, cl_next variables used in list_for_each
loops. The code is more compact and readable

Since CH_Agere_Systems_Mini_PCI_V1 is defined as 0 in hermes_pci_versions
and neither the enum nor the value is used anywhere else, we can drop
the assignment of .driver_data as it is initialized as 0 by default.
