* [Vulkan] Add v2 of context negotiation interface.
* [Vulkan] Add vkEnumerateInstanceVersion symbol.
* [Vulkan] Implement v2 context negotiation
* [libretro] Add GET_HW_CONTEXT_NEGOTIATION_INTERFACE_SUPPORT.
Works around issues in v1 interface where it was not possible to
query what frontend would do when faces with newer interface versions.
This env-call gives stronger guarantees how things have to work.
* [runloop] Implement GET_HW_CONTEXT_NEGOATION_INTERFACE_SUPPORT.
Fairly trivial. Just report the latest version.
* [Vulkan] Add stricted wording around get_application_info in v2.
* [Vulkan] Be more defensive about get_application_info() in v1.
Repurpose vibrate_on_keypress to enable device's standard keypress feedback on overlay key/button state changes
- Add keypress_vibrate function ptr to input_driver_t (only implemented on Android for now)
- (Android) Remove APP_CMD_VIBRATE_KEYPRESS
- (Android) Add doHapticFeedback, called directly to avoid latency
* Add View feature
Add saving of a filter set in the Explore menu into a so called "View" file which then gets listed alongside playlists.
This also adds the ability to filter a category by range in the Explore menu and not just filter on exact matches.
* Menu improvements for explore and views
* Collapse ozone sidebar in view
* Fix problems with the sidebar in explore/view
* Ignore view files in the Qt playlists menu

Looks like Wii U's mkdir() implementation doesn't like trailing
slashes either.
Since we already have an implementation to handle this, I just added
Wii U to it.

Previous work to clean up the HTTP networking code surfaced a bug
in `socket_connect_with_timeout()` that caused connections to
immediately fail. Specifically, achievements stopped working because
the http task code path was rewritten to use
`socket_connect_with_timeout` instead of `socket_connect`.
The bug appears to come down to an unsupported socket option. The final
check is to try to read `SO_ERROR` from the socket, and on WIIU the
`getsockopt()` call returns -1 and sets `lastsocketerr()` (WIIU's
equivalent to errno) to 16.
The fix is to change the logic to only abort the connection if that
`getsockopt()` call succeeds *and* the error is set.
