230f42b697 [ re #1771 ] Do not use Erased to go under binders 
In the `MkFix : f (Fix f) -> Fix f` example, using `Erased` for `f`
makes the type reduce to `[__] (Fix [__]) -> Fix [__]` and because
`[__] e1 ... en` computes to `[__]`, we end up with `[__] -> Fix [__]`
which does not reference `Fix` anymore.

ab36ad71cf Simplify a few Factor proofs 
A few proofs have been rewritten, a few unnecessary cases cut, and
lots of unnecessary "explicit implicits" have been cut. Probably these
implicits were required when the code was initially written, and
inference has improved since then.

Change semantics of lines and unlines function to match Haskell and other languages (#1585) 
* Add trailing newline on non-empty list in unlines

There are several reasons to do that:
* a line in a text file is something which ends with newline,
  and the last line is not special
* `unlines []` should be different from `unlines [""]`
* `unlines (a ++ b) = unlines a ++ unlines b`
* Haskell does it

* Change lines function behaviour

c80a502627 Return Bool from IOArray.writeArray 
As suggested in #1677.

Crashing on out-of-bounds might be more practical, but we can
reconsider it later.

Correct multiplicities when checking Pi binders

04a0f5001f Correct multiplicities when checking Pi binders 
We've always just used 0, which isn't correct if the function is going
to be used in a runtime pattern match. Now calculate correctly so that
we're explicit about which type level variables are used at runtime.

This might cause some programs to fail to compile, if they use functions
that calculate Pi types. The solution is to make those functions
explicitly 0 multiplicity. If that doesn't work, you may have been
accidentally trying to use compile-time only data at run time!

Fixes #1163

5b5bdfe769 [ contrib ] Positions in strings 
This is an alternative to using `fastUnpack` and `fastPack` to work
on lists of characters.

Using this to refactor the lexer and benchmarking the resulting
compiler on building idris2 shows it's 3 to 5s slower than the
current implementation that goes via `List Char`.

This may be backend-dependent so I still push this to contrib,
with the plan of running further benchmarks in the future.
