This patch initializes host_bigendian member of the tep_handle structure
with the byte order of current host, when this handler is created - in
tep_alloc() API. We need this in order to remove tep_set_host_bigendian() API.

In order to make libtraceevent into a proper library, its API
should be straightforward. The trace_seq_printf() and
trace_seq_vprintf() APIs have inconsistent returned values with
the other trace_seq_* APIs. This path changes the return logic of
trace_seq_printf() and trace_seq_vprintf() - to return the number
of printed characters, as the other trace_seq_* related APIs.

tools lib traceevent: Changed return logic of trace_seq_printf() and trace_seq_vprintf() APIs
In order to make libtraceevent into a proper library, its API should be
straightforward.
The trace_seq_printf() and trace_seq_vprintf() APIs have inconsistent
returned values with the other trace_seq_* APIs.
This path changes the return logic of trace_seq_printf() and
trace_seq_vprintf() to return the number of printed characters, as the
other trace_seq_* related APIs.

In order to make libtraceevent into a proper library, its API
should be straightforward. The tep_register_event_handler()
functions returns -1 in case it successfully registers the
new event handler. Such return code is used by the other library
APIs in case of an error. To unify the return logic of
tep_register_event_handler() with the other APIs, this patch
introduces enum tep_reg_handler, which is used by this function
as return value, to handle all possible successful return cases.

tools lib traceevent: Remove tep_data_event_from_type() API
In order to make libtraceevent into a proper library, its API
should be straightforward.
After discussion with Steven Rostedt, we decided to remove the
tep_data_event_from_type() API and to replace it with tep_find_event(),
as it does the same.
