* \brief
* Fixed-size Names
*
* dns_fixedname_t is a convenience type containing a name, an offsets table,
* and a dedicated buffer big enough for the longest possible name.
*
* MP:
*\li The caller must ensure any required synchronization.
*
* Reliability:
*\li No anticipated impact.
*
* Resources:
*\li Per dns_fixedname_t:
*\code
* sizeof(dns_name_t) + sizeof(dns_offsets_t) +
* sizeof(isc_buffer_t) + 255 bytes + structure padding
*\endcode
*
* Security:
*\li No anticipated impact.
*
* Standards:
*\li None.
