04e05e3f86 Fix repeated argument check
As it was, it could break if the argument was repeated more than twice.
When checking dot patterns, we need to check that no further holes are
solved, and that the pattern variable doesn't unify with some other
pattern variable, but if it had already made progress (either for a good
or bad reason) we missed this. Fixes #536

3a6614b227 Look at intermediate results in program search
This has involved quite a bit of reorganisation and some improvements in
resugaring so that the results look nice. In summary:

* Expression search now gives back a RawImp rather than a checked term,
  which allows it to include case expressions
* Case with one pattern is resugared to a destructuring let
* Some name generation issues address in function generation

We look at intermediate results for local variables which are functions
that return a concrete type, or recursive calls that return a single
constructor type. In these cases, we:

* let bind the local variable/recursive call
* generate a new definition for the scope, as a 'case' function

When we recursively generate the definition, it's a bit more restricted
so as not to explode the search space. We only take the first result, we
only look one constructor deep, and we go right to left on variable
splitting so only deconstruct the name we've just added.

8d7fa5c642 Add a heuristic for sorting search results

7083f7ac13 Add a 'reject' count to :gd
This gives the number of implementations to reject before accepting one.
It's intended as a reasonably cheap way of giving multiple results from
interactive editing (e.g. the vim mode, which goes via the REPL and
--client rather than the IDE mode)

Edwin Brady
df635cf8d7 Add :psnext and :gdnext at the REPL
These continue the search from :ps and :gd next respectively, giving the
next search result until there are no more results.
Correspondingly, added ':proof-search-next' and ':generate-def-next' in
IDE mode, which continue the search from the previous ':proof-search'
and ':generate-def' respectively.

6d96341776 Reorganise expression search
Rather than returning a complete list of results, return a pair of the
first result, and a continuation. The continuation explains how to
continue the search if the given result is deemed unacceptable (either
on encountering an error somewhere, or just if the caller wants the next
result).

This means we don't search needlessly if we're only looking for the
first result. Fixes #228

690328421a Delay building references for case blocks
...until the definition is complete. This is necessary since sometimes
information outside the case block can help resolve interfaces, and in
the simplest case, we might just have delayed resolving a default
Integer. It turns out this was also an obscure bug waiting to happen
with coverage checking of nested case blocks (so there's a test update
there too).

f303e469fb Improve elaborator reflection performance
In a 'Bind', normalise the result of the first action, rather than
quoting the HNF. This improves performance since the HNF could be quite
big when quoted back.

Ideally, we wouldn't have to quote and unquote here, and we can probably
achieve this by tinkering with the evaluator.

This has an unfortunate effect on the reflection002 test, in that the
"typed template Idris" example now evaluates too much. But, I think the
overall performance is too important for the primary motivation
behind elaborator reflection. I will return to this!

45a9668370 Export all of the Prelude as Prelude
There is an argument that, for import public, this should be automatic
(that is, the publicly imported things should be reexported with the
parent namespace). I decided not to do this, because another use of
import public which we do a lot in the Idris 2 code base is purely as a
convenience, where we still expect things to be in their original
namespace.
Also, where there's a choice between things being explicit and implicit,
I prefer to err on the side of explicit now.
So, if what you really want in an API is to reexport, you can do that,
but explicitly.

028624a18d Add "import X as Y" properly
Instead of just the cursory name update that we used to do (which didn't
work properly anyway for a lot of reasons), now we add aliases for all
the names in the imported module.
So, like Idris 1, every global has a canonical name by which we can
refer to it, but it can also have aliases via "import ... as".

8ddac9c1d5 Record implicit parameters of interfaces

implicit parameters explicitly when defining implementations.

ebc413ede5 Postpone elaborating lambdas
It's worth delaying in case doing some more work (and some more
interface resolution) can make the type more concrete. This makes
test linear011 work more smoothly, and will help with this sort of
program in general.

A better way, later, would be to try elaborating and delay only if the
type is not yet known. We have the facilities, but it's too fiddly for
me to want to implement it right now...

dbdf7dab3d Back to HasIO, remove MonadIO
Following a fairly detailed discussion on slack, the feeling is
generally that it's better to have a single interface. While precision
is nice, it doesn't appear to buy us anything here. If that turns out to
be wrong, or limiting somehow, we can revisit it later. Also:

- it's easier for backend authors if the type of IO operations is
  slightly less restrictive. For example, if it's in HasIO, that limits
  alternative implementations, which might be awkward for some
  alternative back ends.
- it's one less extra detail to learn. This is minor, but there needs to
  be a clear advantage if there's more detail to learn.
- It is difficult to think of an underlying type that can't have a Monad
  instance (I have personally never encountered one - if they turns out
  to exist, again, we can revisit!)

c9b20911e1 Add linear pair/dependent pair to the prelude
I'm playing with some linear structures and finding these useful a lot,
so good to have a consistent syntax for it. '#' is chosen because it's
short, looks a bit like a cross if you look at it from the right angle
(!) and so as not to clash with '@@' in preorder reasoning syntax.

public export for it to reduce properly. But if they're not, we don't
want them exported or they might affect the module hash and cause

d60feaace0 Add finalisers to Chez back end
This involves new primitives GCPtr and GCAnyPtr which are pointer types
that have finalisers attached. The finalisers are run when the
associated pointer goes out of scope.

In the test, I am assuming that the GC will only be called once, right
at the end. Otherwise, the output isn't guaranteed to be deterministic!
Let's see how this assumption holds...

This is currently Chez only. I think it'll be easy enough to add to
the Racket and Gambit back ends too.

c17d4ff0a5 Look inside case blocks in conversion check
This is quite fiddly as it the blocks might be in different contexts so
we need to keep track of which variables correspond in the scrutinees of
the blocks. Once that's done, check the terms at the leaves convert,
then check the corresponding variables convert.

This may not be perfect yet, because we only look at case scrutinees to
find correspondence. It might also be a bit slower than it could be, but
at least these checks are quite rare.

Fixes #208 and maybe some others?

d5b5af91d1 Implement %macro flag
A %macro must always be fully applied. Whenever the elaborator
encounters a %macro application (except in a function LHS) it evaluates
the application and sends the result to %runElab. So:

%macro
foo : args -> Elab TT
...
def = foo a b c

is equivalent to

foo : args -> Elab TT

def = %runElab foo a b c

c88bf7af8d Fix import loading
This was taking too long, and adding too many things, because it was
going too deep in the name of having everything accessible at the REPL
and for the compiler. So, it's done a bit differently now, only chasing
everything on a "full" load (i.e., final load at the REPL)

This has some effects:
+ As systems get bigger, load time gets better (on my machine, checking
  Idris.Main now takes 52s from scratch, down from 76s)
+ You might find import errors that you didn't previously get, because
  things were being imported that shouldn't have been. The new way is
  correct!

An unfortunate effect is that sometimes you end up getting "undefined
name" errors even if you didn't explicitly use the name, because
sometimes a module uses a name from another module in a type, which then
gets exported, and eventually needs to be reduced. This mostly happens
because there is a compile time check that should be done which I
haven't implemented yet. That is, public export definitions should only
be allowed to use names that are also public export. I'll get to this
soon.

8b062f47cc Allow cli given option overriding for ipkg cmds.
As it was in Idris1 being able to override some, or introduce new, options to an Idris IPKG is beneficial. For example, generate code for multiple codegens from a single source.

Overridable options are:

+ `--verbose`
+ `--timing`
+ `--dumpcases <file>`
+ `--dumplifted <file>`
+ `--dumpvmcode <file>`

eb3cba5f85 Better checking for empty types
This improves coverage checking, because it can now see that things like
(Z = S x) and (x = S x) are empty. Previously, it only checked that all
possible constructors had a disjoint index. Now, it looks for matches
and checks for disjointness in the matches, which catches a lot more
things especially with equality.
