Cumulativity preparation: Add field for universe level to TType (#2076)
* Add field for universe level to TType

This doesn't do anything yet, other than introduce new universe
variables whenever we introduce a new type, but it's the first step
towards checking the universe hierarchy. Next step is to add constraints
when checking pi, unifying/converting types, and when adding data
constructors.

* TTC version increment

Thought I'd done this, but apparently I didn't save the file. Oops!

* Add structure for universe constraints

* Fix display of ambiguity errors

We need to store the Context in errors at the point where the error
occurs, or we might get some nonsense in the message. There's still a
couple of places in Error where we don't do this right. This fixes one
of them, and improves a few messages in the process.

Fix casts in scheme evaluator (#2011)
* Fix casts in scheme evaluator

We really need test cases for all the primitives before we can use this
evaluator properly. Also test cases that run inside an environment,
which are a bit harder to construct.

* Add the cast fixes to racket support code

* More racket compile time evaluation fixes

We had the chez version of some primtives in the ct-support file. We
need a full set of tests for the primitives here too...

Fix performance regression #1991 (#1995)
* Normalise types fully at the REPL

It was a bit odd that we only normalised the scope of function types and
not the arguments, and I can't remember the reason for that if there
even was one.

* Better way of using nf_metavars_threshold

If a term is getting big and probably needs normalising, we now have a
sizeLimit flag in quote, so we can use that instead of checking the size
afterwards. This is a handy heuristic for speeding up unification when
there's a term with lots of suspended computation. Fixes #1991

than to have an `EmptyFC` that does not help.

Experimental Scheme based evaluator (#1956)
This is for compiled evaluation at compile-time, for full normalisation. You can try it by setting the evaluation mode to scheme (that is, :set eval scheme at the REPL). It's certainly an order of magnitude faster than the standard evaluator, based on my playing around with it, although still quite a bit slower than compilation for various reasons, including:

* It has to evaluate under binders, and therefore deal with blocked symbols
* It has to maintain enough information to be able to read back a Term from the evaluated scheme object, which means retaining things like types and other metadata
* We can't do a lot of the optimisations we'd do for runtime evaluation particularly setting things up so we don't need to do arity checking

Also added a new option evaltiming (set with :set evaltiming) to display how long evaluation itself takes, which is handy for checking performance.

I also don't think we should aim to replace the standard evaluator, in general, at least not for a while, because that will involve rewriting a lot of things and working out how to make it work as Call By Name (which is clearly possible, but fiddly).

Still, it's going to be interesting to experiment with it! I think it will be a good idea to use it for elaborator reflection and type providers when we eventually get around to implementing them.

Original commit details:

* Add ability to evaluate open terms via Scheme

Still lots of polish and more formal testing to do here before we can
use it in practice, but you can still use ':scheme <term>' at the REPL
to evaluate an expression by compiling to scheme then reading back the
result.

Also added 'evaltiming' option at the REPL, which, when set, displays
how long normalisaton takes (doesn't count resugaring, just the
normalisation step).

* Add scheme evaluation mode

Different when evaluating everything, vs only evaluating visible things.
We want the latter when type checking, the former at the REPL.

* Bring support.rkt up to date

A couple of missing things required for interfacing with scheme objects

* More Scheme readback machinery

We need these things in the next version so that the next-but-one
version can have a scheme evaluator!

* Add top level interface to scheme based normaliser

Also check it's available - currently chez only - and revert to the
default slow normaliser if it's not.

* Bring Context up to date with changes in main

* Now need Idris 0.5.0 to build

* Add SNF type for scheme values

This will allow us to incrementally evaluate under lambdas, which will
be useful for elaborator reflection and type providers.

* Add Quote for scheme evaluator

So, we can now get a weak head normal form, and evaluate the scope of
a binder when we have an argument to plug in, or just quote back the
whole thing.

* Add new 'scheme' evaluator mode at the REPL

Replacing the temporary 'TmpScheme', this is a better way to try out the
scheme based evaluator

* Fix name generation for new UN format

* Add scheme evaluator support to Racket

* Add another scheme eval test

With metavariables this time

* evaltiming now times execution too

This was handy for finding out the difference between the scheme based
evaluator and compilation. Compilation was something like 20 times
faster in my little test, so that'd be about 4-500 times faster than the
standard evaluator. Ouch!

* Fix whitespace errors

* Error handling when trying to evaluate Scheme

Disable -Xcheck-hashes, at least for the moment (#1940)
* Version increment to 0.5.1

This is to remove the requirement on Chez >9.5

* Disable -Xcheck-hases, at least for the moment

If we're going to have this as an option, we need to have a portable way
of finding a sha256sum command. At the moment, we might find a command,
but different versions accept different options. We should at least
allow setting it via an environment variable, and we certainly shouldn't
fail if running the command fails.

Abandon auto search on undefined name (#1938)
* Abandon auto search on undefined name

These might arise from names in other modules that haven't been
imported. But it's going to be an error whatever, so give up straight
away. Fixes #1925

* Fix typo

* Fix test source

* Record possible cause when we can't solve a goal

Normally, it's just because we searched and failed. But maybe sometimes,
it's because there's an undefined name, in which case, we can include
this in the error message.

This is good to record because it means we don't abandon elaboration at
the wrong time! Say, if a search fails due to an undefined name, but it
was only in one branch of an ambiguous elaboration.

[ refactor ] introduce UserName for (UN/RF) (#1926)
Instead of having UN & RF (& Hole in the near future & maybe even
more later e.g. operator names) we have a single UN constructor
that takes a UserName instead of a String.

UserName is (for now)

```idris
data UserName : Type where
  Basic : String -> UserName -- default name constructor       e.g. map
  Field : String -> UserName -- field accessor                 e.g. .fst
  Underscore : UserName      -- no name                        e.g. _
```

This is extracted from the draft PR #1852 which is too big to easily
debug. Once this is working, I can go back to it.
