Even more TODOs still; plus Grafserv exports

[benjie]

• Renamed getBaseName, baseNameMatches, getOppositeBaseName and getBaseNameFromKeys inflectors to all begin with an underscore (_) - this is because these inflectors should only be used from other inflectors, since they may return non-string types (null/boolean/etc).
  • To fix, just search and replace getBaseName -> _getBaseName, etc.
• Renamed steps from @dataplan/pg to follow the conventions:
  • BooleanFilterStep 👉 PgBooleanFilterStep
  • ClassFilterStep 👉 PgClassFilterStep
  • ManyFilterStep 👉 PgManyFilterStep
  • OrFilterStep 👉 PgOrFilterStep
  • TempTableStep 👉 PgTempTableStep
• Moved a number of *Extensions exports from @dataplan/pg to be in global namespace DataplanPg:
  • PgCodecExtensions -> DataplanPg.PgCodecExtensions
  • PgCodecAttributeExtensions -> DataplanPg.PgCodecAttributeExtensions
  • PgCodecRelationExtensions -> DataplanPgCodecRelationExtensions
  • PgCodecRefExtensions -> DataplanPg.PgCodecRefExtensions
  • PgRefDefinitionExtensions -> DataplanPg.PgRefDefinitionExtensions
  • PgResourceExtensions -> DataplanPg.PgResourceExtensions
  • PgResourceUniqueExtensions -> DataplanPg.PgResourceUniqueExtensions
  • PgResourceParameterExtensions -> DataplanPg.PgResourceParameterExtensions
  • PgConditionStepExtensions -> DataplanPg.PgConditionStepExtensions
• String sorting now consistently uses en-US locale
• tamedevil export toJSON renamed to stringifyJSON (for clarity)
• tamedevil method dangerousKey renamed to safeKeyOrThrow (for clarity)
• @grafserv/persisted now allows configuring the poll interval of the persisted operations folder, and even adds (untested) watch mode (preset.grafserv.persistedOperationsDirectoryScanInterval = number | "watch" (number is in milliseconds, -1 to disable polling/watching))
• Accept header parser implements more of the spec
• Add more grafserv exports to make it easier to implement an alternative Grafserv adaptor:
  • convertErrorToErrorResult
  • convertHandlerResultToResult
  • getBodyFromRequest
  • handleErrors
  • httpError
  • makeGraphQLWSConfig
  • memo
  • normalizeRequest
  • parseGraphQLJSONBody
  • processHeaders
  • Plus types:
    • GrafservBody and underlying types in this union
    • RequestDigest
• Grafserv error masking now generates a hash for the error (hash = sha1(String(error))) in addition to the code, this allows grouping similar errors together (there is a small risk that an extremely highly motivated hacker could use this basic hashing (using the deprecated/broken SHA1 algorithm) to determine the underlying error and stack, but doing so would be incredibly resource intensive if it's even feasible at all).
• Fastify server stream handler rewritten
• Detect when the user uses a preset that contains no plugins or does not contain the QueryPlugin and output an error or warning to guide them
• Improve error messages for getOutputTypeByName and getInputTypeByName
• Handle missing Node fetchers
• Fix exporting of objects with a __proto__ key in graphile-export
