Serd 0.5.0

Serd 0.5.0 has been released. Serd is a lightweight C library for RDF syntax which supports reading and writing [Turtle][], [TriG][], [NTriples][], and [NQuads][]. Serd is suitable for performance-critical or resource-limited applications, such as serialising very large data sets or embedded systems.

Changes:

• Add ability to build static library
• Add serd_env_set_prefix_from_strings for convenience
• Add serd_strerror
• Avoid writing illegal Turtle names as a result of URI qualifying
• Fix erroneously equal SERD_ERR_BAD_SYNTAX and SERD_ERR_BAD_ARG
• Fix pretty printing of successive blank descriptions, i.e. "] , ["
• Gracefully handle NULL reader sinks
