Before this revision, when you pass `context` in the arguments
of a JSON routes, this one gets automatically injected
in the environment context.
This is not the case for regular HTTP routes.
It makes sense to propagate the context for the JSONRPC protocol,
JSON routes used by the backend, such as `call_kw`,
but it doesn't make sense to pass this context automatically
for any other kind of routes, such as front-end routes
or routes used by custom Javascript widgets.
This change brings a more unified behavior for routes
of types HTTP and JSON.
In addition, most developers were not aware of this "feautre",
that passing `context` in the arguments of a JSON route leaded
to the injection of this context in the environment context.
This is actually reflected by the diff size this changes required,
only a dozens of routes needed to be adapted, to manually
add the context in their route arguments and to inject it
in their environment context.

Rationale
---------
Given the following domain:
['|',
('company_id.name', 'like', 'BE'),
('company_id.city', 'like', 'Brussels')]
The ORM would generate the following SQL query:
SELECT "res_partner"."id"
FROM "res_partner"
WHERE "res_partner"."company_id" IN (
SELECT "res_company"."id"
FROM "res_company"
WHERE "res_company"."name" like 'BE'
) OR "res_partner"."company_id" IN (
SELECT "res_company"."id"
FROM "res_company"
WHERE "res_company"."email" like 'help@odoo.com'
);
Which is sub-optiomal as the WHERE clause of the two subqueries could be
regrouped inside of a single query like so:
SELECT "res_partner"."id"
FROM "res_partner"
WHERE "res_partner"."company_id" IN (
SELECT "res_company"."id"
FROM "res_company" WHERE (
"res_company"."name" like 'BE'
OR "res_company"."email" like 'help@odoo.com'
)
);
Postgres-wise, it is faster to execute the latter query than the former
one. This commit is about optimizing the ORM so that it generates
queries where the WHERE clause of compatible subqueries are grouped
together.
Technical solution
------------------
The solution explored by this work is to replace the regular relational
field accesses (over a dotted path) by a new `any` operator that look as
follow:
(relational_field, 'any', domain)
For instance, the above `('company_id.name', 'like', 'BE')` leaf becomes
`('company_id', 'any', [('name', 'like', 'BE')]` using `any`.
Having a domain as right-hand-side allow for the combination of the
domains of same compatible relations:
[('company_id', 'any', ['|',
('name', 'like', 'BE'),
('city', 'like', 'Brussels')])
Having combined domains allows for generating better SQL queries with
minimal changes to the expression parsing algorithm, which can only
translate a single leaf at a time to SQL. With the new `any` operator,
it is still a single leaf but the right-hand-side contains the merged
domain, thus the combined SQL WHERE clause is immediately generated.

The odoo.addons.web.controllers.main module was a very long bloated file
where many different controllers were concatened. It proved difficult to
work on that file on a regular basis,mainly because ctrl-p "web main.py"
was not pointing the right file.
In this work the file has been split on the basic 1 controller = 1 file.
The original way of importing stuff (through main.py) is still possible
thanks to deprecated aliases.
