Anna Schumaker fc88f68d6b tests: Build file test with ctest 
This changes test output slightly, in that files are now placed under
subdirectories of $XDG_USER_DATA_DIR/ocarina-test/ instead of in this
directory directly.  This should help avoid conflicting files, and lets
me use a single "rm" command to remove everything before testing.

Anna Schumaker 1633946981 core/file: Check if a file is too new to be opened 
I'm hitting this problem while developing 6.5, since file formats are
going to change.  Let's handle this situation gracefully rather than
segfaulting.

This patch changes versioning problems into fatal errors to prevent us
from overwriting data already on disk.

Anna Schumaker 12949651f7 core/file: Add struct cache_file 
I want to reuse as much file code as I can for cache files, but I need a
new struct since data and cache files track different properties.

Anna Schumaker 9e0f017e61 core/file: Build in minimum version checks 
I don't think it makes sense that callers of file_open() are expected to
check the file version after opening.  This should be something handled
by the file code so we can print a consistent error message.

Anna Schumaker ee4f0d4c89 core/file: Writes go to a temporary file first 
And then rename the temporary file when closed.  This protects users
data in case Ocarina gets killed.

Anna Schumaker 08394c3168 core/file: Add a C-style initializer macro 
I eventually intend to remove the file_init() function, once everything
has been converted to C.
