[PATCH v6 02/25] refs/files-backend.c: new file, renamed from refs.c

From: Ronnie Sahlberg <redacted>

We are about to split up the reference code into multiple source
files, to separate the generic code from the code that is specific to
the current files-based backend. To keep things organized, we will
move the reference-related code to a subdirectory, "refs/". Over time,
more files will appear in this subdirectory.

As the first step, rename refs.c to refs/files-backend.c. This file
will eventually contain only the code specific to the files-based
backend. In subsequent commits we will move backend-agnostic code to a
new refs/refs.c file that will hold the common refs code that is
shared across backends.

The reason for first moving all the code to refs/files-backend.c and
then moving the backend agnostic code back to refs/refs.c instead of
moving refs.c to refs/refs.c first is because the code that will
eventually remain in this new files-backend.c file is so entangled
that it would then be very difficult to break the split up into small
independent patches/chunks.
