The `no-useless-regex-char-class-escape` custom lint rule was introduced
as a less aggressive alternative to some enhancements that were
introduced into ESLint. Those enhancements were blocking us from
updating ESLint. However, they have since been relaxed and the custom
rule is no longer needed. Remove it.

In preparation for applying the more strict indentation linting
available in ESLint 4.0.0, correct minor indentation issues in
tools/eslint-rules/required-modules.js.

This is the only file with indentation that does not conform to the
stricter checks.

* Remove needless RegExp flag

  In fixed case, `/g` flag is needless in the boolean context.

* Remove needless RegExp capturing

  Use non-capturing grouping or remove capturing completely when:

  * capturing is useless per se, e.g. in test() check;
  * captured groups are not used afterward at all;
  * some of the later captured groups are not used afterward.

* Use test, not match/exec in boolean context

  match() and exec() return a complicated object,
  unneeded in a boolean context.

* Do not needlessly repeat RegExp creation

  This commit takes RegExp creation out of cycles and other repetitions.

  As long as the RegExp does not use /g flag and match indices,
  we are safe here.

  In tests, this fix hardly gives a significant performance gain,
  but it increases clarity and maintainability,
  reassuring some RegExps to be identical.

  RegExp in functions are not taken out of their functions:
  while these functions are called many times
  and their RegExps are recreated with each call,
  the performance gain in test cases
  does not seem to be worth decreasing function self-dependency.
