Profile tabs move into Wolfram

Cobalt had its own copy of the profile tabs: names, filters and the cycle order. Indigo only showed a person's posts. The tabs are now one Wolfram module, and both clients call it.

Changes

• Wolfram wolfram/profile_tab.h: wf_profile_tab_name, _filter, _next, and wf_agent_get_profile_tab_typed. The fetch lives in its own file, so the names and cycle can be linked into unit tests without the agent. Released in v0.36.0, split in v0.36.2 (#181, #182, #183).
• Cobalt (#197): Cobalt's copies are deleted; the tab enum now uses Wolfram's values. Cobalt v0.8.1 carried this.
• Indigo (#67): the posts screen gains replies, media and (on the signed-in account only) likes. Tapping the header box cycles them. Shipped in Indigo 0.11.0.

Verification

• Cobalt: the host checks and the sweep and linkcheck pass at merge.
• Indigo: the host tests include the cycle test, and the 3DS cross-build links. Not run on a 3DS or in Azahar.
