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.

63e127094e Improved parsing for literate modes.
The tokenizer for literate modes was incorretly detecting code lines in text.
This PR fixes that, and allows for empty code lines.

0cc54ff145 Propagate visibility appropriately to case/with
If a function is public export, the local definitions also need to be
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
unnecessary rebuilds.

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.

93022af74e More explicitness in evaluator return type

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?

9fab367f0f Reflect differently on LHS
On the LHS, we want to match against the reflected thing, so FC and
implicits need to turn into match anything patterns, or we won't match
anything at all. This means we can put quoted terms on the LHS, with
pattern variables under ~().

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:

+ `--quiet`
+ `--verbose`
+ `--timing`
+ `--dumpcases <file>`
+ `--dumplifted <file>`
+ `--dumpvmcode <file>`
+ `--debug-elab-check`

This is mostly to make it easier to write linear function types without

in the scope.

I don't know how complete this is, but it certainly detects some of the

Still a couple of things to resolve in coverage and totality checking

Also working on this has caught a few totality errors in the Idris 2
code base that Idris 1 missed... so these are fixed on the way.

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.

As in Idris 1 - if an interface declares a method as total or covering,
then all implementations have to satisfy that.

Temporarily turn off %default directive again, at least until totality

from various places because I'll forget to put them back)
