Subject: [PATCH v7] libtracefs: Add initial support for meson

Introduce Meson as build framework for building libtracefs.

The build steps are:

# configure using .build as build directory and install destination
  # /tmp/test
  meson setup --prefix=/tmp/libtraceevent .build

# trigger the build
  meson compile -C .build

# In case you want to build the documentation, trigger the
  # build via the 'docs' target:
  meson compile -C build docs

# install the library (and documentation)
  meson install -C .build

---
 v7:
 - set default html doc path to share/doc/libtracefs-doc
 - list libtraceevent in Required pkg-config section.
 - install (any) man5 pages (keep it in sync with other projects)

v6:
 - changed project defaults to --default-library=both
 - code style consistency updates
 - hardening doc install script (shellcheck)
 - renamed install-man.sh.in to install-docs.sh.in
 - install-docs.sh.in installs html pages too
 - introduces docs target
 - updated copyright year
 - streamlined documentation meson build file

v5:
 - build unit test only if cunit is found
 - default build target is debug
 - do not install man pages into subdirs
 - install sqlhist (because we install the man page too, so why not the tool?)

v4:
 - add subdir include path to cflags in pkgconfg file
 - refactoring build instruction for section 1 and section 3 documentation
   into one loop (reduce code duplication)

v3:
 - build documetation
 - build samples
 - set default location to /usr/local

v2:
 - updated commit message
 - dropped the include path patch, the pkg-config
   from libtraceevent is including them

v1:
 - initial version
