In a template, have t-set t-value outside a t-foreach
in the t-foreach, alter that variable by resetting it (as for a incrementation variable)
Before this commit, when printing the variable when the loop had finished
its value was the one set in the first place
After this commit, the value becomes the one altered by the loop iterations

The way keys were handled in QWeb was mostly ok, but a little naive. It
is fine when we deal with a list of dom nodes, since the reconciliation
algorithm need only to be able to differentiate/reconcile nodes in that
list, but it is an issue with components, which needs to globally be
able to find themselves in their parent's children map.
Because of the way this was handled, there were situations were Owl
internal virtual dom would crash, since components wrongly assumed that
they were already rendered in a different place.
To fix this, we generalize the way keys are generated, by concatenating
all sub keys coming from each iteration loops.

While it is not tested, nor documented, the reference QWeb
implementation display the `false` value as "false". So, we have to
adapt the Owl implementation to match that behaviour.
At the same time, this commit uses 'let' instead of 'var' in various places,
to make the compiled code more consistant.
- In some cases, we can simply inline a template key instead of assigning
it to a variable and then using that variable
- Add component name in generated code for components
This commit is a significant refactoring of the internal of QWeb. It
simplifies the way variables/scoping and slots interact together. The
main idea is that we use a simple scope object instead of a
context/var/scope object.
This commit also implement the actual correct QWeb semantic for the
t-call directive with a sub body. Before, we simply extracted the
variables from the body and injected them at the top of the sub
template. We now simply compile the body before the sub template.
This is a joint work with Lucas (lpe).

Have a t-call having a t-raw="0"
that call is made to a template of the same form
i.e. itself as a t-call t-raw="0" structure
Before this commit, there was recursion crash
This was because the caller to which a t-raw="0" referred to
was incorrect. The caller here is the node which makes the t-call.
In particular, the caller was always set to last caller of the context
After this commit, there is no crash and this imbrication
of t-call and t-raw="0" is well rendered.
To sum up, we count the recursive calls to t-raw="0" and fetch
the caller in the context accordingly
