patch 8.0.1674: libvterm can't handle an OSC string split

Problem:    Libvterm can't handle a long OSC string that is split.
Solution:   When an incomplete OSC string is received copy it to the parser
            buffer. Increase the size of the parser buffer to be able to
            handle longer strings.
