Move the platform plugins into a private directory, versioned with the relevant ABI.

Together with Alan's versioning of libmirplatform, makes different versions of Mir parallel installable again.

Fixes: https://bugs.launchpad.net/mir/+bug/1293944

Move the platform plugins into a private directory, versioned with the relevant ABI.

There are some obvious TODOs here, but none seem super-urgent:
*) Actually managing the lifetime of our platform plugins rather than just keeping them around indefinitely
*) Defining an ABI we expose to platform plugins and then sticking them in an unversioned directory.
*) Loading the specific version of the ABI we expect via dlvsym.

Things that I'll do as an immediate follow-on branch:
*) Logging for platform module probing

How does removing libmirplatform fits with our "platform" story?

AIUI libmirplatform is the LGPL foundation (establishing common interfaces & types) that both a propitiatory platform implementation and the GPL libmirserver link against.

How is that seen to work after these changes?

Besides the conflicts:

Debian packaging guidelines mandate lib<name><version>, so e.g. libmirclientplatform-mesa8 for the package names. The extra dash before the version is only used if the name ends with a number.

We need to check if removing alternatives support breaks the emulator use case (which was the driving force behing it).

Roughly the same as it was working before these changes - if, for example, you check out libmirplatform in trunk then you'll see it exports a single symbol - mir::load_library - which I removed and then noticed that nothing was actually linked against libmirplatform (because we pass the linker flag to only link against things that we use symbols from).

Thinking of which, have we checked with our lawyers and/or NVIDIA's/AMD's lawyers about this? The situation is more like loadable modules in the kernel rather than traditional dynamic linking, and it'd be nice to be clearer about our expectations than the kernel is.

Ah, yeah. I'll actually go the other way - this isn't a shared library, it's a module, so I'll rename it mir-platform-graphics-mesa-24 (see also: Xserver versioning)

It shouldn't be too hard to get a basic probe up and running. I'll do so.

Ah, yeah. This was a holdover of trying to use raw mir::SharedLibrary which isn't default-constructible.

I'm not entirely clear what you're concerned about here. Is your concern about testability? That should be mitigated by the MIR_CLIENT_PLATFORM_LIBRARY and MIR_SERVER_PLATFORM_LIBRARY environment overrides, which we need to use in the tests anyway?

I wasn't party to the conversations with lawyers, I'm going on what kgunn told us.

Drop noexcept from create_platform declaration.

Since we're returning a std::shared_ptr<> we're pretty much guaranteed that both sides
of this call are actually C++, and can deal with exceptions.

This means we need to expose all the necessary symbols for exception propagation and
so on, so drop the local: catch-all clause from the modules' symbols.map

Probe client platform modules before attempting to create a ClientPlatform

Exceptions aren't flow-control constructs, this will allow platforms to *actually* throw
an exception if ClientPlatform construction unexpectedly fails, and resolves a weird
leak found by valgrind that's probably to do with exception throwing across DSOs without
appropriate symbol exports.

Be smarter about the client platform tests.

We can instantiate the parametrised multiple times, so do it individually for Mesa and Android
if they're built, rather than testing the dummy for each platform not built. The dummy platform
is not yet sufficiently dummy to work properly here.

Select the right client platform for integration tests.

The Android integration tests have some Android-specific tests that need a real client platform,
so give it to them.

Conversely, the Mesa client platform cannot load in the integration test environment, as they need
a real platform package.

Default to logging our choice of platform library.

This is both so I can see what the hell's happening in CI, but is also
a reasonable default¹. Who wants to receive bug reports where we don't know
what platform libraries are being loaded?

¹: For the server, certainly. Less reasonable for the client, until we make
the client log hookable.
