[merp] Use a separate program as the hang supervisor. (mono/mono#15715)

* [merp] Use a separate program as the hang supervisor.

Fixes https://github.com/mono/mono/issues/15646

macOS does not like signals being sent from the forked supervisor process, possibly towards anywhere but definitely when sent to the parent process. The following message is currently spewed after the supervisor process attempting to send a SIGSEGV to a hanged Mono process:
"The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec()."

We follow that direction and introduce a new binary that, when available in the mono executable's binary directory, is used to abort the parent process for us.

[arm] respect I1 and I2 on gsharedvt out transition

In order to trigger the problem, we must call into gsharedvt code ("in" transition) and then escape the gsharedvt world ("out" transition). The bug happens in the latter. Also some other stars need to align (I haven't fully understood it), thus the repro is quite long.

[netcore] Make the load hook ALC-aware (mono/mono#16012)

The meat of this PR is what the title suggests, and with this commit all the basic ALC functionality should be working properly. Probably worth checking if this makes any new tests pass.

Additionally, this PR includes a second commit that switches over the search hook to use loaded_assemblies from the ALCs. This may break some existing tests due to remaining unimplemented ALC behavior, notably the native loading mechanism needed for Openssl in some of the cryptography tests. My inclination is to include the commit regardless and just disable the failing tests so that any future ALC work can watch for regressions in the loader, but I would appreciate input from steveisok on how important those tests are. I've not disabled anything yet in order to see exactly what new failures are introduced.

Remove error_init from native icall wrappers since managed does it. (mono/mono#15943)

Preferable would be native only, i.e. for interpreter and for when
it is actually unused, but ok for now.

Between removing the managed and the native, managed is preserved
in case there uses of MonoError in C# other than icall wrappers.
Keep them safe.

But again ideally move it to native and remove the managed type,
pending debugging WebAssembly failure doing so.

Enable MONO_ARCH_EMULATE_FCONV_TO_U4 on PPC (mono/mono#15991)

Fixes regression related to floating point introduced in mono/mono#15930.

This does mean we have to take a slower path instead of using the
PPC instruction, but it provides consistent results. Other CPUs
have to do this too, so it's not like PPC is impacted unfairly.
(i.e, NaN gives an inconsistent result, at least with POWER7 and
some amd64 CPUs tested)

[netcore] Implement referenced assembly resolving and ALC.GetLoadContext (mono/mono#15946)

* [netcore] Implement GetLoadContext

The process is described in
https://docs.microsoft.com/en-us/dotnet/api/system.runtime.loader.assemblyloadcontext?view=netcore-3.0#usage-in-the-runtime

We try four things until one of them returns a non-null assembly.

1. Check if the assembly is already loaded in the ALC of the requesting
assembly.
2. If the ALC is not the default ALC, invoke the Load override.
3. Try the default ALC (TPA - trusted platform assemblies) loading.
4. Invoke the Resolving event of the original ALC.

The implementation borrows some managed code from
https://github.com/dotnet/coreclr/blob/mono/mono@8ba2e15201361402acd0ae9710bd37d50785cdfa/src/System.Private.CoreLib/src/System/Runtime/Loader/AssemblyLoadContext.CoreCLR.cs#L84-L187

[netcore] Use mono-netcore to run real world apps using `dotnet run` (mono/mono#15942)

So currently we have two .NET Core:

1) `mono-repo/.dotnet` - we use it to bootstrap and build stuff (the SDK version is specified in `global.json`) - if you open `netcore/Makefile` it's referred there as `$(DOTNET)` variable.
2) `mono-repo/netcore/.dotnet` - it's just a runtime + CoreFX libs (it doesn't contain SDK stuff, templates, msbuild, etc) - we use it only to run tests because this runtime is synchronized with corefx tests in `eng/Versions.prop` file which is updated by a bot and `netcore/shared` sources for our System.Private.CoreLib also depend on that exact runtime version (the sources also updated by the bot).

This PR introduces a rule to copy mono bits to the `mono-repo/.dotnet` folder to be able to run real world apps (at your own risk) using mono-netcore (so when you run `mono-root/.dotnet/.dotnet run -c Release` for an app - even MSBuild will use mono runtime to build that app). However in theory we need exact SDK for the runtime version we have but I have no idea where and how to get one.

BTW, currently MSBuild crashes when it's powered by mono on `$(DOTNET) build` command for a hello world.

* [marshal] Free delegates with target that are passed to native code.

For static method delegates, we have a unique delegate_trampoline that is shared among all delegates. We always keep alive the first static method delegate passed to native, by creating a normal gchandle to it and storing it in delegate_hash_table. For instance methods, each delegate will create a separate wrapper and these wrappers are never shared (which was wrongly assumed in https://github.com/mono/mono/commit/mono/mono@caa4a753ca8e15d43baaa01adb0f56f374b74a2b). We shuldn't keep the delegate alive and this commit reverts the behavior for delegate with instance methods introduced in the mentioned commit.

Remove error_init from native icall wrappers since managed does it.
Preferable would be native only, i.e. for interpreter and for when
it is actually unused, but ok for now.

Between removing the managed and the native, managed is preserved
in case there uses of MonoError in C# other than icall wrappers.
Keep them safe.

But again ideally move it to native and remove the managed type,
pending debugging WebAssembly failure doing so.

[tests] Bump sleep for pinvoke3 test (mono/mono#15937)

On some operating systems, this test can take forever because the worker starves the other threads by holding the gc_lock. Bump sleeping so it doesn't rely on OS scheduling that much and guarantees other threads can progress in reasonable amount of time.

* Disable the `strerror` cache on Haiku. On Haiku, errors begin at `0x8000_0000` like a Win32 HRESULT. This means the indexing would be on negative numbers, which is a no-no. There are a few alternative ways to keep it though: hashtable, tuple array, offset...

Unfortunately, doesn't build all the way through. Has a tendency to bomb out during building `build-unix`. Will investigate why.

Some frames will be larger, i.e. dynamic + pinvoke.

Classic technique:
pointer instead of struct
initialized to null
alloca it when needed and not null

A more detailed analysis might enable better, such as making
the parameter optional, and/or having the callee default it to its
local storage.

Fix race condition and use less memory in mono_lookup_icall_symbol. (mono/mono#14532)

It is racy because it is doing on-demand initialization, which is often racy.

The rewrite changes the result to be one pointer, atomically swapped, which implies a full barrier and data dependency, so no race.

It could also be fixed by copying and sorting an array of pairs, and one pointer to that.

However in order to save memory I instead use indirect data that is an array of uint16 pointing into the original data. That is a slight memory vs. time tradeoff.

Yes there is debugging code left, under #if, that I prefer to leave, both as evidence that I tested it, and to make it somewhat but ideally testable in future.

The code also was using an unnecessary somewhat risky but probably ok here way to compare pointers, that I fixed.

As well the result is marginally smaller and faster because it was inlining something like bubblesort, now reuses qsort.

---

The failure is happening when we are doing mono_class_setup_fields ("BaseClass<T>") which needs to decide for each field whether it is blittable or not. So therefore we are trying to decide if ValueTest<T> (that is: the ValueTest<U> field inside BaseClass<T>) is blittable or not.

So we instantiate U with T.
Now to decide whether VaueTest<T> is blittable or not, we look at every field.
So then we look at T value.
To decide if T is blittable we first check if it's a reference type.

That check is currently inadequate for generic parameters - what the PR adds is the ability to see if theres a T : class constraint or a T : C constraint - where C is some class. As soon as we know that T's constraint will force it to be a reference type we can definitely say that T won't be blittable without having to initialize C, at all.

Previously, Mono would see that T is some kind of type for which it couldn't definitively decide that it's a reference type and it would call: mono_class_setup_fields (field_class) which would then try to setup the fields of the parent class BaseClass<T>. And that would hit the recursion check.
