wifi_files: client interface stats, convert to C++
1. client interface stats
Rearrange code to move stats to a separate struct.
For AP, output every associated client.
For STA, output stats of local client interface.
2. convert to C++, remove libglib dependency
libglib is one of the largest files in the GFMN100
filesystem, and appears to only be used by wifi_files
for g_hash support. Convert wifi_files to C++ and use
unordered_map instead. libstdc++ is even larger than
libglib but is used by a bunch of stuff in the system
already, so we're better off being dependant on it
than on glib.
