[PATCH v2 3/8] ui-repolist: Create context structure for cgit_print_repolist()

[Tim Nordell]

This is in preparation of moving the code that iterates over the
repository list into a walk pattern.  This walk pattern will permit
other views on the repository list more easily, such as a section
only list.
