* Pass `dirname` as extra metadata to preset constructor.
Sometimes a preset would like to know where it should resolve relative paths from (e.g. https://github.com/tleunen/babel-plugin-module-resolver) and this extra information makes that possible.
* Test for `dirname` passed into preset constructor
This adds a check for `dirname`’s existence and correctness to the
`resolve-addons-relative-to-file` test, and serves as a minimal example
of a path-aware preset.
Remove imports to lodash/assign and replace assign with Object.assign.
The lodash/assign is unnecessary for babel 7 as node >4 has the same
functionality built-in with Object.assign as used here.
This resolve the [issue 5353](https://github.com/babel/babel/issues/5353)
This encapsulates the logic for turning an acceptable preset name into
the absolute path for that preset. It can be used to preprocess a
presets list to map each preset to its absolute path, which is necessary
if `babel.transform` is going to be executed on a file outside the
directory subtree where the presets are installed.
This adds a getPossiblePresetNames helper encapsulating the logic for
what preset names we should try to resolve, and the resolvePreset method
just calls this helper and actually resolves them.

* fix(shouldIgnore): filename normalization should be platform sensitive
shouldIgnore normalizes the path of the filename prior to running any "only" regexes or functions. The normalization uses "slash", which has some undesirable special cases for non-ASCII characters and longer paths. Changing the normalization behavior to always replace path separators.
There is no real need to add additional tests, because the tests are not run in an environment where path.sep !== '/'.
* Minor style fix to use double quotes.
* Remove conditional for regex replace to keep consistent behavior.
* whitespace [skip ci]
