`Given` with `Always` from Idris 1 library are completely overridden by
`IsYes` and `ItIsYes` respectively, which have a more common naming.
This, however, may break some very old code (fixed by a trivial rename).
Modern compilers should be smart enough regardless and generate
efficient code for the sequence of ifs, this is really just a syntax
change to make the code shorter.
e79e4277 ("[ fix ] Make Bits types use int switch statement in RefC")
made the RefC backend generate code calling `extractInt` with Bits
types, bit did not add the extra cases to `extractInt`. This commit adds
the missing cases.
Fixes#2452
This causes issues whenever you have a FFI function taking `()` as an
argument. (Not that such a function is really useful, and I assume this
is the reason the issue hasn't been noticed so far.)
* RefC backend improvements
1. OnCollect had the wrong number of arguments. The code creator expects
3 arguments, but onCollect in prim.h expected 4 arguments. The first of which
was an erased arguments. That is now fixed.
2. OnCollect did not call `newReference` when creating a new reference to the pointer
and the freeing function
3. OnCollect and OnCollectAny still had a spurious printf statement
Those issues have been fixed, the test case can be found in
tests/refc/garbageCollect
4. The IORef mechanism expects that the %World token will be passed around
consistently. This is not the case. States in Control.App make use of
IORefs, but the function created from Control.App.prim_app_bind
had the world token erased to NULL.
Now, IORefs are managed using a global variable,
IORef_Storage * global_IORef_Storage;
referenced in cBackend.h, defined in the created .c file, and set to NULL
in main();
5. While multithreading and forking is still not supported, compiling a program
that makes use of Control.App demands a C implementation of prim_fork.
Files support/refc/threads.c and support/refc/threads.h provide a
dummy implementation for it, so that Control.App programs compile and run.
A test for these 2 issues is given in tests/refc/issue2424

The local paths (`../../CONTRIBUTING.md`) and even the absolute paths (`/CONTRIBUTING.md`) depend on which GH page you're on -_-
This sets the reference to a URL, meaning it should (hopefully) just point to the right thing for everyone now.
* Allow functions to be marked for foreign export
This relies on the backend knowing what to do with such things, but the
general idea is to mark them with '%export "backend:exportedname"' then
'getCompileDataWith', given a back end, will search for every function
that needs to be exported, as well as every function starting from the
expression to be compiled. This will allow Idris functions to be called
from other languages, where a backend supports it.
This is hard to set up a test case for, for the moment, since no
backends actually do anything with it. So consider it a bit of a
placeholder for now.
* Add missing clause to Eq FnOpt

I got fed up with being puzzled whenever edwin's trailing commas
and my leading commas clash and the error location is the opening
square bracket rather than the repeated comma.
Previously we were using namespaces as a poor approximation of
source file. We're now actually looking at the source file the
definition arose from in order to decide whether to keep it.
See e.g. base's Data.DPair for a drastic change.
Additionally, we sort definitions by definition location rather
than alphabetical order to respect the user's decision to introduce
some things before other.
