* [BUGFIX] Add provided schema under a dummy / internal URI (fixes #376) (#378)

* Add provided schema under a dummy / internal URI (fixes #376)

In order to resolve internal $ref references within a user-provided
schema, SchemaStorage needs to know about the schema. As user-supplied
schemas do not have an associated URI, use a dummy / internal one instead.

* Add more unit tests (#366)

mbstring is on all test platforms, so this line will never be reached.

* Fix infinite recursion on some schemas when setting defaults (#359) (#365)

* Don't try to fetch files that don't exist

Throws an exception when the ref can't be resolved to a useful file URI,
rather than waiting for something further down the line to fail after
the fact.

* Refactor defaults code to use LooseTypeCheck where appropriate

* Test for not treating non-containers like arrays

* Update comments

* Rename variable for clarity

* Add CHECK_MODE_ONLY_REQUIRED_DEFAULTS

If CHECK_MODE_ONLY_REQUIRED_DEFAULTS is set, then only apply defaults
if they are marked as required.

* Workaround for $this scope issue on PHP-5.3

* Fix infinite recursion via $ref when applying defaults

* Add missing second test for array case

* Add test for setting a default value for null

* Also fix infinite recursion via $ref for array defaults

* Handle nulls properly - fixes issue #377

* Add option to also validate the schema (#357)

* Remove stale files from #357 (obviated by #362) (#400)

* Stop #386 sneaking in alongside another PR backport
