/*
Scan the string starting at ptr until the end of the next complete token,
but do not scan past eptr.  Return an integer giving the type of token.

Return XML_TOK_NONE when ptr == eptr; nextTokPtr will not be set.

Return XML_TOK_PARTIAL when the string does not contain a complete token;
nextTokPtr will not be set.

Return XML_TOK_INVALID when the string does not start a valid token; nextTokPtr
will be set to point to the character which made the token invalid.

Otherwise the string starts with a valid token; nextTokPtr will be set to point
to the character following the end of that token.

Each data character counts as a single token, but adjacent data characters
may be returned together.  Similarly for characters in the prolog outside
literals, comments and processing instructions.
