With this commit, component only render child
components if they have different props (shallow
equality). Otherwise, we trust the reactivity
system to make sure that all impacted components
are updated
Before this commit, portal was a Component, now is a directive.
This commit also clean some unused code, and fix an issue on the clean
optimization when a portal is found in a condition or a loop.
The slot inner working has been reworked. A prop "slots" is now passed
explicitely to the component. It looks like
{ slotName_1: slotInfo_1, ..., slotName_m: slotInfo_m }
with the objects slotInfo_i with mandatory keys "__render", "__ctx",
and optional key "__scope" and possibly others.
Here is how a slotInfo object can be created:
A slotInfo object is normally created by setting in a template something
like
<div>
<t t-set-slot="foo" t-set-scope="scope" param_1="var" param_2="3">
content
<t t-esc="scope.bool"/>
<t t-esc="scope.num"/>
</t>
</div>
and it will be used somewhere like
<div>
<t t-esc="props.slots.foo.param_1"/>
<t t-slot="foo" bool="other_var" num="5">
</div>
In the above example, the function "__render" produces the block dom
element for the content of the t-set-slot.
The context "__ctx" will have a key "scope" with value { bool: ..., num: 5 }
and "__scope" will be set to "scope".
t-out automatically escaped content when it is a string not marked
with the `markup` function
t-out renders the raw content if it is a Block, or if it has been marked
with the `markup` funtion.
t-esc has been kept since it is safe and is optimized to render text nodes.
all t-raw calls are in fact the same as t-out.
