* Add basic JSON serializer
For now, it only handles Arrays of Integers, but we'll extend it to
support all of the common types
* Serialize Strings
* Escape quotes in Strings
* Escape backslashes in Strings
* Serialize Hashes with String keys
* Extract method for serializing Strings
* Add test coverage for non-Hash non-Array JSON serialization
* Add test for unexpected key types
* Serialize Hashes with Symbol keys
* Raise on unexpected value types
* Serialize boolean values
* Serialize Floats
* Add module comment to Puma::JSON
* Update integration test to use fully-qualfied JSON module reference
* Remove json gem dependency from /stats status server response
Fixes a bug where requesting `/stats` from the status server would cause
subsequent phased restarts to fail when upgrading/downgrading the json
gem.
* Run gc_stats tests on JRuby
These were disabled at some point on JRuby, but they seem to run fine.
Importantly, this test ensures that a call to `/gc-stats` returns
well-formed JSON on JRuby, where the value of `GC.stat` contains nested
structures.
* Remove json gem dependency from /gc-stats status server response
Fixes a bug where requesting `/gc-stats` from the status server would cause
subsequent phased restarts to fail when upgrading/downgrading the json
gem.
* Remove json gem from /thread-backtraces status server response
Fixes a bug where requesting `/thread-backtraces` from the status server
would cause subsequent phased restarts to fail when
upgrading/downgrading the json gem.
* Remove json gem dependency from Puma.stats
Fixes a bug where accessing `Puma.stats` would cause subsequent phased
restarts to fail when upgrading/downgrading the json gem.
* Fix test name in json test

* Add History entry
* Add test for exceptions on values of unexpected types
* Update test name for additional clarity
* Reorder cases to match order in ECMA-404
* Allow all serializable inputs in Puma::JSON::serialize
The pervious implementation was based on and older JSON standard which
defined JSON texts to be either objects or arrays. Modern JSON standands
allow all JSON values to be valid JSON texts.
* Update JSON tests to test value types directly
* Reorder tests to roughly match source order
* Add test for serializing integers as JSON
* Serialize nil as null
* Use block form of gsub instead of hash form
* Escape control characters as required by ECMA-404
* Collapse handling of Symbol and String into one case
* Extract constants used in string serialization
* Remove superflous else case
* Use stringio for incremental JSON construction
* Extract test helper for testing JSON serialization
* Assert that strings generated by Puma::JSON roundtrip when using ::JSON
* Use a recent version of the json gem in tests
`::JSON.parse` doesn't handle JSON texts other than objects and arrays
in old versions
* Handle default expected_roundtrip more explicitly for clarity

* Add test to change the version of nio4r gem in phased restart
* Add test to change the version of json gem in phased restart
* Remove use of json gem when handling worker stats messages
* DRY up gem change phased restart tests
* Add History entry
