Look at these sentences:
Elle aime tout ce qui brille.
She likes everything that shines.
J'adore tout ce que cet auteur a publié.
I love everything (that) this writer has published.
Both the expressions tout ce qui and tout ce que mean all/everything that.
However, they're used in different contexts.
Tout ce qui = all/everything that...
Use tout ce qui when the pronoun qui is followed by a verb or an object/reflexive pronoun (as opposed to a subject pronoun -je/tu/il/elle/on/nous/vous/ils/elles - or a noun):
Elle aime tout ce qui brille.
She likes everything that shines.
Tout ce qui me plaît te dégoûte.
Everything that pleases me disgusts you.
Nor can you contract qui into qu'.
Compare this with: Qui = Who, which, that (relative pronouns) and Ce qui (vs ce que) = what, which (relative pronouns)
Tout ce que = all/everything that...
Use tout ce que when the pronoun que is followed by a subject pronoun (je/tu/il/elle/on/nous/vous/ils/elles) or a noun (as opposed to a verb or an object/reflexive pronoun):
J'adore tout ce que cet auteur a publié.
I love everything (that) this writer has published.
Elle dépense tout ce qu'elle gagne en vêtements.
She spends everything (that) she earns on clothes
But you will contract que into qu' in front of a vowel or mute h.
Compare this with: Que = Whom, which, that (relative pronouns) and Ce que (vs ce qui) = what, which (relative pronouns)

You are correct in that "qui" is never shortened to "qu' " before a vowel.
In the sentence you quote, it is actually "que" that got shortened. It can't be "qui" because "qui" is used only for the subject of the subordinate clause.
In the case at hand, the subject is "il" and "ce que" is the direct object.
Here is an example:
Everything that he does annoys me.
Ils me demandent ce qui m'intéresse.
They ask me what interests me.

Tout ce qui should be correct = as it is the subject of m'agace and yes the object of il fait

"Ce que" is correct, because "il" is the subject of the clause and "ce que" is the direct object. It belongs to the same clause whose verbe is "fait".
Tout ce qu'il fait m'agace. -- Everything he does annoys me.
Je trouve tout ce qu'il fait énervant. -- I find everything he does annoying.
In the first sentence "tout ce qu'il fait" is the subject of "m'agace". Whereas in the second sentence it is the direct object of "Je trouve". As you see, in both cases "ce que" is required because it is determined by its relationship to "il fait".
