Description:
The definition of the data structure fil_node_t is private to fil0fil.cc.
Diagnostics code outside that module cannot access information about the files belonging to a tablespace without expensive copying.

How to repeat:
Read the code.

Suggested fix:
Move the definition of fil_node_t to fil0fil.h, where fil_space_t is already defined.
Also, feel free to clean up some function comments related to tablespaces and tablespace files.

Fixed as of the upcoming 5.7.8, 5.8.0 releases, and here's the changelog
entry:

The definition of the "fil_node_t" data structure was moved from
"fil0fil.cc" to "fil0fil.h" so that diagnostic code outside that module
can access information about files that belong to a tablespace.
