[v3,0/3] Split logging functionality out of EAL

  There is a general desire to reduce the size and scope of EAL. To this
end, this patchset makes a (very) small step in that direction by taking
the logging functionality out of EAL and putting it into its own library
that can be built and maintained separately.

As with the v1 RFC for this, the main obstacle is the "fnmatch" function
which is needed by both EAL and the new log function when building on
windows. While the function cannot stay in EAL - or we would have a
circular dependency, moving it to a new library or just putting it in
the log library have the disadvantages that it then "leaks" into the
public namespace without an rte_prefix, which could cause issues.  Since
only a single function is involved, this v2 RFC takes a different
approach to v1, and just moves the offending function to be a static
function in a header file. This allows use by multiple libs without
conflicting names or making it public.

The other complication, as explained in v1 RFC was that of multiple
implementations for different OS's. This is solved here in the same
way as v1, by including the OS in the name and having meson pick the
correct file for each build. Since only one file is involved, there
seemed little need for replicating EAL's separate subdirectories
per-OS.

NOTE: documentation updates are still missing in v3, will come in v4.
Submitting v3 to allow CI testing and check that v2 broken builds are
now working

v3:
* Fixed missing log file for BSD
* Removed "eal" from the filenames of files in the log directory
* added prefixes to elements in the fnmatch header to avoid conflicts
* fixed space indentation in new lines in telemetry.c (checkpatch)
* removed "extern int logtype" definition in telemetry.c (checkpatch)
* added log directory to list for doxygen scanning
