[PATCH v5 0/3] MR5812: odbccp32: SQLWritePrivateProfileStringW check for existing DSN first

[Alistair Leslie-Hughes (＠alesliehughes)]

If a DSN is System wide, we need to write to the HKEY_LOCAL_MACHINE
part of the registry not HKEY_CURRENT_USER which it's currently doing.

--
  v5: odbccp32: SQLWritePrivateProfileStringW simplify creating registry keys.
      odbccp32: SQLWritePrivateProfileStringW check for existing DSN first.
      odbccp32: SQLGetPrivateProfileString use ConfigMode to determine key retrieval.
