David Howells 4f73175d03 X.509: Add utility functions to render OIDs as strings
Add a pair of utility functions to render OIDs as strings.  The first takes an
encoded OID and turns it into a "a.b.c.d" form string:

	int sprint_oid(const void *data, size_t datasize,
		       char *buffer, size_t bufsize);

The second takes an OID enum index and calls the first on the data held
therein:

	int sprint_OID(enum OID oid, char *buffer, size_t bufsize);
