Tests for recent C fixes

[eafer]

These are the updated test schemas for the recently merged C generator patches. As requested by @wing328 here:

By the way, there are a few warnings in the test build that seem to be a recent regression:

[wing328]

thanks for adding a new test schema

have you added the new files too using git add?

[eafer]

What new files? Did I mess something up? I thought I just needed to update the schema with the new cases that were failing.

[eafer]

Oh, you mean for the samples? Yes, I added everything.

[wing328]

from the build error message:

[ 66%] Building C object CMakeFiles/openapi_petstore.dir/model/tag.c.o

looks like the c petstore is trying to import preference (enum) but no luck.

does the C petstore client support enum models? or it only supports inline enum?

[eafer]

You are right, I messed up at some point during rebasing. I'll send the rest of the samples now.

[eafer]

I just added the missing files, sorry for the confusion.

can you please update the samples one more time?

[eafer]

Ok, done. Sorry, I have no idea how I keep messing this up.

[wing328]

No problem bro. Thanks for adding the test.
