parser: extract function that tests if next token may start new term

Future patches will separate primary expression and prefix operator actions.
This function will be used to resolve ambiguity of them.

This is a step to remove the old-style revexpr parser. We need both ":" and
":y" operators for backward compatibility.

#require execbit

Create extension that can disable exec checks:

  $ cat > noexec.py <<EOF
  > from mercurial import extensions, util
  > def setflags(orig, f, l, x):
  >     pass
  > def checkexec(orig, path):
  >     return False
  > def extsetup(ui):
  >     extensions.wrapfunction(util, 'setflags', setflags)
  >     extensions.wrapfunction(util, 'checkexec', checkexec)
  > EOF
