revset: factor out getinteger() helper
We have 4 revset functions that take integer arguments, and they handle
their arguments in slightly different ways. This patch unifies them:
- getstring() in place of getsymbol(), which is more consistent with the
handling of integer revisions (both 1 and '1' are valid)
- say "expects" instead of "requires" for type errors
We don't need to catch TypeError since getstring() must return a string.
