[tor-commits] [tor/master] add_c_file: Rename variables based on the type of path
commit eb336e23a6a0979cf0c8e68f3dcd6a825a4b210d
Author: teor <teor@xxxxxxxxxxxxxx>

add_c_file: Rename variables based on the type of path
* fname for generic file paths
* tor_fname for paths relative to the top-level tor directory
* src_fname for paths relative to tor's src directory
With prefixes as required to disambiguate different paths of the same
type.
Part of 32962.
