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 previous 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.
