Changes include:

  embedded platforms (Issue #141)

  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)

  (Issue #138)
- Fixed error handling in the low-level TLS read/write functions.

Enjoy!
