Waaay faster TJSONScanner.

* Fix compilation in unicode rtl

Use varints for TJSONScanner.FParts to save memory.

* JSON Schema

* Rename keyword info to avoid confusion

* Flush when saving. Fixes issue gitlab 0040938

* Only flush when actually writing

* Add foFormatFloat option to FormatJSON. Fixes issue gitlab 0040937

* Make flush virtual. Fixes issue gitlab 0040942

* Inline documentation of TJSONOption. Fixes issue gitlab 0040943

* Update some comments

* Add readfromscanner, fix reading type

* Pascal code generation starting from json-schema

* JSON Writer

* Refactor to use jsonwriter

* Remove references to openAPI

* Forgot to commit

* Some cleanup, fix warnings/hints

* Tests for code generation. Change type handling to create pascal type data for all data

* SortProperties public

* Calculate dependencies correctly, only generate definitions for schema types

* OpenAPI, initial commit

* Fixes in array type handling

* Add newline after uses clause

* Corrections when writing file: write in 3.1 format

* Do not call parsing if JSON is empty (e.g. return 204 with empty body)

* System.Types for Delphi code

* Search for correct element type when checking array types

fcl-json: less hints

* Add possibility to specify UTC or not

* Generate also string (enum) type definitions

* Fix naming for string types

Faster FormatJSON.

fpjson.pp adjustments: 37.5% growth, remove unused NCachedIndents, de-unoptimize potentially usable IndentSize = 0.

* Remove debug statement

* Generate API array types

* Sanitize property names and type names

* Not all types may need serialization

* Serialize arrays of basic types

* Remove some more debug statements

fcl-json: clean up

Reducing unnecessary UTF8<->String encoding conversions

* Support anonymous types in arrays

Resolve array elements

better handling of array types

Remove implicit string conversion. The digits of the number will always be less than $7F. ~7%

StringParse - without unnecessary conversions, speedup~12%

Use JSONType for checking, "is" is heavier, speedup~3%

IndexOfName (string finalization) another speedup ~1%

Calculating string length immediately, speedup 2.5%

ParseString string finalization ~0.5–1%

Remove finalization calls in TJSONObject.Create(Elements), speedup~2.5%

Fewer warnings

Build the string immediately if there are no special encoded characters, speedup ~6%

* Fix gitlab 0041563

* Raise exception in case of no JSON and joSingle. Fix issue gitlab 0041588

* Allow to "reserve" type names which need to be transformed

* Fix checking of interdependent types

* More keywords

* Additional standard types

* More reserved types

* More reserved types

* mechanism for de-duplicating identifiers, and shortening long identifiers

* Additional case of duplicate names

Delphi compatibility.

* Fix issue gitlab 0040835

* Use memorystream as a kind of tstringbuilder for json escaping(StringToJSONString), fixes bug 0039525

* improved version that is still readable and has hex inline. Most importantly, it writes directly to result string rather than a temp, saving a copy that is hurting specially for longer strings.
