* 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
* Polyfill memrchr(3) for non-GNU systems

Several changes:
* Soft-Deprecate Buffer() constructors
* Add `Buffer.from()`, `Buffer.alloc()`, and `Buffer.allocUnsafe()`
* Add `--zero-fill-buffers` command line option
* Add byteOffset and length to `new Buffer(arrayBuffer)` constructor
* buffer.fill('') previously had no effect, now zero-fills
* Update the docs

Many variables in the buffer tests are redeclared. Change them so that
they are scoped appropriately.

If the needle contains an extended latin-1 character then using
String::Utf8Length() will be too large and the search will return early.
Instead use String::Length() when encoding is BINARY.

Currently the signature is indexOf(val[, byteOffset[, encoding]])
Instead allow indexOf(val[, byteOffset][, encoding])
so that byteOffset does not need to be passed.

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.

Adds the string search implementation from v8
which uses naive search if pattern length < 8
or to a specific badness then uses Boyer-Moore-Horspool
Added benchmark shows the expected improvements
Added option to use ucs2 encoding with Buffer::IndexOf

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.
