  embedded platforms (Issue #141)
• Updated httpAddrLookup to return a numeric address when the resolver
  returns "localhost" for a non-loopback address.
• Updated cupsFileGetConf and cupsFilePutConf to escape more characters.
• Updated cupsRasterReadHeader to validate more of the page header values.
• Updated ippeveprinter to support custom "printer-state-reasons" keyword
  values (Issue #142)
