Many of the tests use variables to track when callback functions
are invoked or events are emitted. These variables are then
asserted on process exit. This commit replaces this pattern in
straightforward cases with common.mustCall(). This makes the
tests easier to reason about, leads to a net reduction in lines
of code, and uncovered a few bugs in tests. This commit also
replaces some callbacks that should never be called with
common.fail().

There are a few places where tests repeatedly concatenate strings to
themselves in order to make them very long. Using `.repeat()` makes the
code clearer.
For example, before:
for (var i = 0; i < 8; ++i) lots_of_headers += lots_of_headers;
After:
lots_of_headers = lots_of_headers.repeat(256);
Using `.repeat()` makes it clear that the string will be repeated 256
times rather than 8 times. ("What?! That first one doesn't repeat 256
times! It only repeats 8... Oh, wait. Yes, I see your point now.")

common.js needs to be loaded in all tests so that there is checking
for variable leaks and possibly other things. However, it does not
need to be assigned to a variable if nothing in common.js is referred
to elsewhere in the test.

Enable linting for the test directory. A number of changes was made so
all tests conform the current rules used by lib and src directories. The
only exception for tests is that unreachable (dead) code is allowed.
test-fs-non-number-arguments-throw had to be excluded from the changes
because of a weird issue on Windows CI.
