assert.deepEqual and assert.deepStrictEqual currently return true for
any pair of Maps and Sets regardless of content. This patch adds
support in deepEqual and deepStrictEqual to verify the contents of Maps
and Sets.

Deeo equivalence checking is currently an
O(n^2) operation, and worse, it gets slower exponentially if maps
and sets were nested.

Note that this change breaks compatibility with previous versions of
deepEqual and deepStrictEqual if consumers were depending on all maps
and sets to be seen as equivalent. The old behaviour was never
documented, but nevertheless there are certainly some tests out there
which depend on it.

Support has stalled because the assert API was frozen, but was recently
unfrozen in CTC#63.

---

Later squashed in:

This change updates the checks for deep equality checking on Map and Set
to check all set values / all map keys to see if any of them match the
expected result.

This change is much slower, but based on the conversation in the pull
request its probably the right approach.

Adds support for the PSS padding scheme. Until now, the sign/verify
functions used the old EVP_Sign*/EVP_Verify* OpenSSL API, making it
impossible to change the padding scheme. Fixed by first computing the
message digest and then signing/verifying with a custom EVP_PKEY_CTX,
allowing us to specify options such as the padding scheme and the PSS

This is a fix for test-child-process-exec-kill-throws which is currently
flaky on Windows.

A bug in the test was causing the child process to fail for reasons
other than those intended by the test. Instead of failing for exceeding
the `maxBuffer` setting, the test was failing because it was trying to
load `internal/child_process` without being passed the
`expose-internals` flag. Move that module to where only the parent
process (which gets the flag) loads it.

Additionally, improve an assertion message to help debug problems like
this.

Some of the tests for `buffer.includes()` functionality introduced in
https://github.com/nodejs/node/pull/3567 have been broken in a way that
caused them to always pass regardless of the result of the tested
method.

This behavior was caused by two reasons:

 * These tests were written as though `buffer.includes()` was supposed
   to return the same value that `buffer.indexOf()` does, i.e., used
   indices or -1 as expected return values instead of true and false.
 * `assert()` was used as the assertion function to do that instead of
   `assert.strictEqual()`.

Thus `assert()` was called with a non-zero number as the first argument
effectively causing these tests to pass.

This commit changes the tests to use `assert.ok()` and removes redundant
indices.
