Add a skeleton for new library: libtracefs, providing APIs
for accessing files from tracefs. The library files are added in
lib/tracefs
include/tracefs
It is built and installed by trace-cmd targets
make libs
make install_libs
A unit test framework is added, as POC patch, to test the APIs
of the library. It requiers CUnit test framework to be installed
on the machine. A new target is added to build the unit test:
make test
[
v3 changes:
- Renamed few APIs, to match the naming convention used commonly
- Optimized tracefs_iterate_raw_events() API
- Added unit test infrastructure
- Few minor changes
v2 changes:
- Fix copyright of the newly created files
- Remove tracefs_write_file() API, add it as a local helper function
