Serd 0.20.0

Serd 0.20.0 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 -lm to pkg-config libs
• Correctly handle posix_memalign failure
• Don't write xsd:decimal literals to Turtle bare if they would not be read back with the same type
• Fix const-correctness violation for reader input string
• Fix possible crash in serd_writer_end_anon() when writing invalid lists
• Generate blank names like :b1 and :B2 not :genid1 :docid2
• Support new RDF 1.1 Turtle
• Update to waf 1.7.14
