scan_cescape - parse C escaped string

       scan_cescape  parses C escaped text from src into dest.  Parsing stops at the 0 terminator, invalid input
       characters or a double quote that was not escaped.

       C escape sequences like \n and \x0a and \012 are translated  into  their  binary  counterparts.  The  C99
       escape sequences \u and \U are supported and lead to UTF-8 sequences being output.

       scan_cescape  will  then  write the number of bytes in dest into *destlen, and return the number of bytes
       decoded from src.

       dest can be NULL. destlen can be NULL. dest can be src.

       To make sure dest is large enough, either allocate strlen(src)+1 bytes or call  scan_cescape  twice,  the
       first time with dest == NULL (*destlen will still be written).
