Program interface changes

• TypeChecker.emitFiles is no longer available; use Program.emit instead.
• Getting diagnostics are now all centralized on Program,
  • for Syntactic diagnostics for a single file use: Program.getSyntacticDiagnostics(sourceFile)
  • for Syntactic diagnostics for all files use: Program.getSyntacticDiagnostics()
  • for Semantic diagnostics for a single file use: Program.getSemanticDiagnostics(sourceFile)
  • for Semantic diagnostics for all files use: Program.getSemanticDiagnostics()
  • for compiler options and global diagnostics use: Program.getGlobalDiagnostics()

Tip: use ts.getPreEmitDiagnostics(program) to get syntactic, semantic, and global diagnostics for all files

All usages of 'filename' and 'Filename' changed to 'fileName' and 'FileName'

Here are the details:

• CompilerHost.getDefaultLibFilename => CompilerHost.getDefaultLibFileName
• SourceFile.filename => SourceFile.fileName
• FileReference.filename => FileReference.fileName
• LanguageServiceHost.getDefaultLibFilename => LanguageServiceHost.getDefaultLibFileName
• LanguageServiceShimHost.getDefaultLibFilename => LanguageServiceShimHost.getDefaultLibFileName

The syntacticClassifierAbsent parameter for the Classifier.getClassificationsForLine is now required

See Pull Request #2051 for more details.

Changes to TextChange

TextChange.start and TextChange.length became properties instead of methods.

SourceFile.getLineAndCharacterFromPosition

SourceFile.getLineAndCharacterFromPosition became SourceFile.getLineAndCharacterOfPosition

APIs made internal as they are not intended for use outside of the compiler
