3a7aedf0f4 Add reflection under (explicit) binders
This allows writing a staged well typed interpreter, for example (see
reflection008 test)

c682ded9c4 Reduce amount of normalisation in elab scripts
We don't want to unfold definitions in 'pure' or 'check' or 'bind' since
we want the exact expression that the script author has used.

08b56e9e75 Add quote operation to Elab
Allows quoting a term back to a TTImp. Test reflection007 shows one
possible use for this, building a reflected, type safe, representation
of an expression.

2a75731916 In reflection, check now takes a concrete type
So the type of Elab now gives the expected type that's being elaborated
to, meaning that we can run 'check' in the middle of scripts and use the
result.

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 ~().

a9f334ef5c Added auto_implicit_depth pragma
By default, the search depth for auto implcit arguments is limited to
50. This patch adds a new pragma `%auto_implicit_depth` with which the
user can change the depth limit.

c3ee2a3fac Change genSym behaviour
Instead of merely generating a locally unique name, use the existing
code for generating a new unique variable name in the unifier, which is
therefore globally unique.

a33136aa00 A couple more elab reflection primitives
Get the names of local variables. and add the ability to look up their
types.
When we get a reflected TTImp, either checking the Goal or looking up a
type, it's not impossible that there'll be some repeated binder names,
so also make sure binders are unique relative to the current context.
Ideally we'd also rename things in the environment to guarantee that all
names are unique, but we don't yet.

(This would be much easier if reflected terms were typed such that they
were well scoped, but that would also make reflection harder to use.)

3d2765e930 Add top level %runElab
This invokes a script of type Elab (). %runElan in a term invokes a
script of type Elab TT. The elaborator now pushes in that type, so that
it'll report an appropriate error if you give it a script of the wrong
type.

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

e001d266fe Add sys/time.h to satisfy xcode.
It seems relevant to all BSD systems.

In xcode the option -Wno-error-implicit-function-declaration is enabled. So the following error occured:
Idris2/support/c/idris_file.c:76:13: Missing '#include <sys/time.h>'; declaration of 'select' must be imported from module 'Darwin.POSIX.sys.time' before it is required

I hope it won't break anything on linux.

The bootstrap version has an occasional bug with as patterns, which is

work this way!)

26e6e1ed82 Calculate compile time references even in case
If we don't do this, we don't look inside case blocks to check they
cover, and so we might miss coverage errors in nested case blocks.
