• Add support for new language argument
• Added multipart/form-data for endpoints which support it
• Fix enum for proper C# codegen
• Replace fancy quotes with plain single quotes for Java compile
• Changes to make --azure-validator run more cleanly, details:

Errors Fixed

• XmsExamplesRequired/D5001/Documentation (7)
• XmsPathsMustOverloadPaths/R2058/SDKViolation (7)

Errors Ignored

• SecurityDefinitionsStructure/R2054/SDKViolation (1) - API Key scheme for Cognitive Services
• APIVersionPattern/R3012/ARMViolation (1) - Keeping with the Cognitive Services numbering scheme
• OperationsAPIImplementation/R3023/ARMViolation (1) - Not sure what this is

Warnings Fixed

• XmsEnumValidation/R2018/SDKViolation (1)
• DescriptionAndTitleMissing/R4000/SDKViolation (1)

Warnings Ignored

• DescriptionAndTitleMissing/R4000/SDKViolation (35) - description is contained in #ref
• EnumInsteadOfBoolean/R3018/ARMViolation (5) - fix would be a breaking change
• ListInOperationName/R1003/SDKViolation (1) - fix would be a breaking change
• LongRunningOperationsWithLongRunningExtension/R2007/SDKViolation (2) - endpoint will not ultimately yield a 200, as this extension would require
• NonApplicationJsonType/R2004/ARMViolation (15) - fix would be breaking change
• PageableOperation/R2029/SDKViolation (1) - not actually pageable
• ParameterNotDefinedInGlobalParameters/R2015/SDKViolation (1) - All our own parameters specify x-ms-parameter-location
• PostOperationIdContainsUrlVerb/R2066/SDKViolation (7) - fix would be breaking change

I think the breaking-change script is picking up the fact the overload specification was change to placate --azure-validator. So whereas we previously had:

#/paths/analyze?overload=url
#/paths/analyze?overload=stream

we now have:

#/paths/analyze
#/paths/analyze?overload=stream

The rule in question is XmsPathsMustOverloadPaths/R2058/SDKViolation. Let me know if there's correct/better way to fix this.
