Move socket file to /run on Linux
/var/run  is considered legacy on Linux, the replacement is
/run . systemd v239+ started complaining about services and other unit files using
/var/run. We should migrate to the new path, and ndn-cxx should look for the socket file in
/run first (on Linux only).
On most, if not all, modern Linux distros
/var/run is a symbolic link to
/run, so I don't expect any disruption.

What do you mean by "handle"? Whatever value appears in the config file takes precedence over the (hardcoded) default.
Sorry, I mean the default. By default, the config file refers to
/var/run/nfd.sock. I see four possible solutions (please let me know what you think of each):
- (a) Have different default config files for each platform (seems difficult and error-prone, especially with keeping the two versions consistent).
- (b) Perform some processing at compile-time to put different defaults for each platform in the config file (seems like overkill).
- (c) Leave
/var/run/nfd.sockin the config file, since this still works on Linux due to the symbolic link, and have the hardcoded default in the code be platform-specific (easiest).
- (d) Leave
/var/run/nfd.sockin the config file, but comment it out so that the hardcoded platform-specific path in code is used by default (my preferred solution, seems easy and not hacky - can also add a comment indicating default values for each platform in the config file).
