* [tests] Preserve all test fixtures.
This fixes the wildly diffetent number of tests when running xammac tests with and without linking.
Without linking:
> Tests run: 2446 Passed: 2321 Inconclusive: 9 Failed: 0 Ignored: 125
vs with linking:
> Tests run: 1885 Passed: 1802 Inconclusive: 4 Failed: 0 Ignored: 83
Now we run the same tests either with or without linking.
One test was updated to not fail when linking is enabled.
Also add a test to ensure all future test fixtures are preserved.
* Remove whitespace noise.
This change allows to ignore the use of cookies and cookie containers in
the NSUrlSessionHandler. There are two different cookie containers to
consider:
1. The native NSHttoCookieStorage.
2. The managed CookieContainer.
If the native one is set to null, the native code will not use a cookie
storage, which is used as a flag to ignore the managed one.
There is an interesting situation, we allow different types of sessions.
From the cookie storage point of view, Default and Background sessions
are the same, but Ephemeral is not, since we only want to store in ram
the cookies and do not share them.
This supposes a problem because Apple does not provide any API that will
allow to determine the session type use in the configuration. The
workaround has been to hide the direct native call for the configuration
and add an enum value that can later be accessed in the
NSUrlSessionHandler. Of course things cannot be that easy. When a
session is created with the configuration, it creates a copy, and the
internal session configuration does not longer have the flag, therefore,
we need to store the session type in the handler.
