This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.
The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.
This has the side effect that `common` is used significantly less
frequent.

ERR_INVALID_ARG_TYPE is the most common error used throughout the
code base. This improves the error message by providing more details
to the user and by indicating more precisely which values are allowed
ones and which ones are not.
It adds the actual input to the error message in case it's a primitive.
If it's a class instance, it'll print the class name instead of
"object" and "falsy" or similar entries are not named "type" anymore.

ESLint 4.x has stricter linting than previous versions. We are currently

changes the indentation of files to comply with the stricter 4.x linting
and enable stricter linting in the test directory.

Allow all methods on `buffer` and `Buffer` to take `Uint8Array`
arguments where it makes sense. On the native side, there is
effectively no difference, and as a bonus the `isUint8Array`
check is faster than `instanceof Buffer`.

A new version of ESLint flags chained properties on multiple lines that
were not flagged by the previous version of ESLint. In preparation for
turning that feature on, adjust alignment to that expected by the
linter.
This change happened to be predominantly around assertions using
`assert()` and `assert.equal()`. These were changed to
`assert.strictEqual()` where possible.

When node began using the OneByte API (f150d56) it also switched to
officially supporting ISO-8859-1. Though at the time no new encoding
string was introduced.
Introduce the new encoding string 'latin1' to be more explicit. The
previous 'binary' and documented as an alias to 'latin1'. While many
tests have switched to use 'latin1', there are still plenty that do both
'binary' and 'latin1' checks side-by-side to ensure there is no
regression.

Fix `buffer.lastIndexOf()` for the case that the first character
of the needle is contained in the haystack, but in a location that
makes it impossible to be part of a full match.
For example, when searching for 'abc' in 'abcdef', only the 'cdef'
part needs to be searched for 'c', because earlier locations can
be excluded by index calculations alone.
Previously, such a search would result in an assertion failure.
This applies only to Node.js v6, as `lastIndexOf` was added in it.

Fix `buffer.indexOf` for the case that the haystack has odd length
and the needle is not found in it. `StringSearch()` would return
the length of the buffer in multiples of `sizeof(uint16_t)`, but
checking that against `haystack_length` would not work if the latter
one was odd.

Use `StringBytes::Size` to determine the needle string length
instead of assuming latin-1 or UTF-8.
Previously, `Buffer.indexOf` could fail with an assertion failure
when the needle's byte length, but not its character count,
exceeded the haystack's byte length.

* Remove unnecessary templating from SearchString
SearchString used to have separate PatternChar and SubjectChar template type
arguments, apparently to support things like searching for an 8-bit string
inside a 16-bit string or vice versa. However, SearchString is only used from
node_buffer.cc, where PatternChar and SubjectChar are always the same. Since
this is extra complexity that's unused and untested (simplifying to a single
Char template argument still compiles and didn't break any unit tests), I
removed it.
* Use Boyer-Hoore[-Horspool] for both indexOf and lastIndexOf
Add test cases for lastIndexOf. Test the fallback from BMH to
Boyer-Moore, which looks like it was totally untested before.
* Extra bounds checks in node_buffer.cc
* Extra asserts in string_search.h
* Buffer.lastIndexOf: clean up, enforce consistency w/ String.lastIndexOf
