This patch series includes changes, related to transformation of
traceevent into a library:
Renamed few libtracevent APIs.
Introduced two new APIs: tep_get_ref() and tep_override_comm().
Removed tep_data_event_from_type() API.
Changed return logic of tep_register_event_handler() and trace_seq_printf()
Added support for pkg-config infrastructure
Changed describtion of few APIs, to be consistent with the man pages.
v2 combines all recent API related pacthes, which are still not accepted
into one series. It also removes any dependencies between them and the
man page related changes.
v3 splits patch
"tools/lib/traceevent: Changed return logic of tep_register_event_handler() API"
into 2 patches:
"tools/lib/traceevent: Changed return logic of tep_register_event_handler() API"
"tools/lib/traceevent: Remove tep_data_event_from_type() API"

This patch implements new API of the tracevent library:
int tep_get_ref(struct tep_handle *pevent);
The API returns the reference counter "ref_count" of the tep handler.
As "struct tep_handle" is internal only, its members cannot be accessed
by the library users, the API is used to get the reference counter.

This patch implements integration with pkg-config framework.
pkg-config can be used by the library users to determine
required CFLAGS and LDFLAGS in order to use the library

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. This renames struct tep_event_format to struct tep_event,
which describes more closely the purpose of the struct.

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. This renames tep_free_format() to tep_free_event(),
which describes more closely the purpose of the function.

In order to make libtraceevent into a proper library, its API
should be straightforward. The __tep_data2host*() functions are
going to no longer be available as a libtraceevent API, tep_read_number()
should be used instead. This patch replaces __tep_data2host*() usage with
tep_read_number() in perf.

In order to make libtraceevent into a proper library, its API
should be straightforward. This patch hides few API functions,
intended for internal usage only:
tep_free_event(), tep_free_format_field(), __tep_data2host2(),
__tep_data2host4() and __tep_data2host8().
The patch also alignes the libtraceevent summary man page with
these API changes.

This patch adds a new API of tracevent library: tep_override_comm()
It registers a pid / command mapping. If a mapping with the same
pid already exists, the entry is updated with the new command.

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, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_".
This patch renames struct cmdline to struct tep_cmdline.

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.

In order to make libtraceevent into a proper library, its API
should be straightforward. After discussion with Steven Rostedt,
we decided to rename few APIs, to have more intuitive names.
This patch renames tep_is_file_bigendian() to tep_file_bigendian().

APIs descriptions should describe the purpose of the
function, its parameters and return value. While working
on man pages implementation, I noticed mismatches in the
descriptions of few APIs. This patch changes the description
of these APIs, making them consistent with the man pages:
tep_print_num_field(), tep_print_func_field(),
tep_get_header_page_size(), tep_get_long_size(),
tep_set_long_size(), tep_get_page_size() and
tep_set_page_size().

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.

New functions should use "tep" instead of "pevent". We need to start
removing that name.
I'll just change this patch directly so that you don't need to send a
v4. But for future patches, lets avoid pevent. And when we start
touching functions that use it, we should rename it.

Might want to run checkpatch.pl before sending, as it can catch
whitespace issues. The above "fi" has a tab after it.

This too.
I applied the rest of this series except for this patch. If you want,
you can fix this patch up and resend it as a stand along (but label it
as v4).
