Subject: RTTI/JSON (#2021)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Use 'Process' to communicate with an command line tool.

* Remove slang-win-stream

* Tidy up windows ProcessUtil.

* First version of BufferedReadStream.

* Windows working IPC for steams.

* Test proxy count option.

* Split Process/ProcessUtil. Process is platform dependant. ProcessUtil are functions that are platform independent.

* First implementation of Unix Process interface.

* Unix process compiles on cygwin.

* Fix typo in unix process.

* Separate unix pipe stream error of invalid access, from pipe availability.

* Fix in standard line extraction.

* Make fd non blocking.

* Fix issues with Windows Process streams.

* Added UnixPipe.

* Some fixes around UnixPipeStream.

* Make a unix stream closed explicit.

* Hack to debug linux process/stream.

* Revert to old linux pipe handling.

* Pass executable path for unit tests.
Split out CommandLine into own source.

* Small improvements in process/command line.

* Check process behavior with crash.

* Make stderr and stdout unbuffered for crash testing.

* Only turn disable buffering in crash test.

* Disable crash test on CI.

* Fix crash on clang/linux.

* Enable crash test.
Remove _appendBuffer as can use StreamUtil functionality.

* Added inital processing for http headers.

* Small improvements to HttpHeader.

* First pass HTTPPacketConnection working on windows.

* Enable other Process communication tests.

* Update comments.

* WIP JSON RPC.

* Add terminate to Process.
Made JSONRPC a Util.

* Small tidy up around HTTPPacketConnection.

* Improve process termination options.

* WIP for test-server.

* Add diagnostics error handling to test-server.

* Improved JSON support.
Parsing/creating JSON-RPC messages.

* WIP JSONRPC parsing.

* First pass RttiInfo support.

* WIP converting between JSON/native types.

* Project files.

* Split out RttiUtil.
Made RttiInfo constuction thread safe.

* WIP RTTI<->JSON.

* Add diagnostics to JSON<->native conversions.

* Make RttiInfo for structs globals. Avoids problem around derived types (like pointers), being able to cause an abort.

* Add pointer support to RTTI.
Fixed some compilation issues on linux.

* Add fixed array support.

* Added Rtti unit test.

* Add rtti unit test.

* Split out quoted/unquoted key handling.
Fix bugs in JSON value/container.
Added JSON native test.

* Make default array allocator use malloc/free.
Remove the new[] handler (doesn't work on visuals studio).

* Fix for linux warning.

* Remove some test code.

* Fix issues on x86 win.

* Fix warning on aarch64.
