NEWS for the sigsum-c 1.0.0 release

	This is the initial release of the sigsum-c library. For API
	documentation, see doc/sigsum-c.md, for build instructions,
	see README.md.

	When building a shared library from this release, the library
	name is libsigsum.so.0.0, with soname libsigsum.so.0.

	Main features:

	* Support for parsing the ASCII representation of Sigsum
	  policy files, Sigsum proofs, and OpenSSH public key files.

	* Support for verifying Sigsum proofs. The main verification
	  functions are written with constrained embedded systems in
	  mind. They work with a bytecode representation of the
	  policy's quorum rule, and do not require use of the ASCII
	  representation.

	* A command line tool sigsum-c-verify, intended to be
	  compatible with the sigsum-verify tool from the sigsum-go
	  package (the main missing feature in sigsum-c-verify is
	  support for named policies).
