Add SSSD specific error codes and definitions

This code adds a new range of error codes specific to SSSD,
It also provides helper functions to print out error defintions
like you can do with system error messages and the strerror() function.

The sss_strerror() function can accept both the new sssd errors and
system errno_t errors falling back to the system strerror() if the error
code provide is not a valid SSSD error code.
