minijail: Introduce the ~ unary operator and parenthesized constants This is useful to avoid having to type out the hex constant for negating a constant (e.g. |~PROT_WRITE|). This also introduces parenthesized expressions, so that people can write |~(FOO|BAR)|, which is the next natural thing to expect once unary operators are introduced. Bug: None Test: make tests Change-Id: I980059c6d482762390c4a1c9b4197df54596b5f0
