Historically `error.errno` of system errors thrown by Node.js
can sometimes be the same as `err.code`, which are string
representations of the error numbers. This is useless and incorrect,
and results in an information loss for users since then they
will have to resort to something like
`process.binding('uv'[`UV_${errno}`])` to get to the numeric
error codes.
This patch corrects this behavior by always setting `error.errno`
to be negative numbers. For fabricated errors like `ENOTFOUND`,
`error.errno` is now undefined since there is no numeric equivalent
for them anyway. For c-ares errors, `error.errno` is now undefined
because the numeric representations (negated) can be in conflict
with libuv error codes - this is fine since numeric codes was
not available for c-ares errors anyway.
Users can use the public API `util.getSystemErrorName(errno)`
to retrieve string codes for these numbers.

Adds a new `../common/fixtures' module to begin normalizing
`test/fixtures` use. Our test code is a bit inconsistent with
regards to use of the fixtures directory. Some code uses
`path.join()`, some code uses string concats, some other
code uses template strings, etc. In mnay cases, significant
duplication of code is seen when accessing fixture files, etc.
This updates many (but by no means all) of the tests in the
test suite to use the new consistent API. There are still
many more to update, which would make an excelent Code-n-Learn
exercise.

In preparation for a lint rule that will enforce
assert.deepStrictEqual() over assert.deepEqual(), change tests and
benchmarks accordingly. For tests and benchmarks that are testing or
benchmarking assert.deepEqual() itself, apply a comment to ignore the
upcoming rule.
