Rename check*Permission* to has*Permission

The check*Permission methods are a bit error-prone because people
can forget to check the return value and expect that they behave
like the enforce* methods. This was pointed out before in some bugs.

This change adds @CheckResult annotation to enforce linter warning
and rename methods accordingly.
