Previously, both the Unix and Windows front ends would respond to a paste action by retrieving data from the system clipboard, converting it appropriately, _storing_ it in a persistent dynamic data block inside the front end, and then calling term_do_paste(term), which in turn would call back to the front end via get_clip() to retrieve the current contents of that stored data block. But, as far as I can tell, this was a completely pointless mechanism, because after a data block was written into this storage area, it would be immediately used for exactly one paste, and then never accessed again until the next paste action caused it to be freed and replaced with a new chunk of pasted data. So why on earth was it stored persistently at all, and why that callback mechanism from frontend to terminal back to frontend to retrieve it for the actual paste action? I have no idea. This change removes the entire system and replaces it with the completely obvious alternative: the character-set-converted version of paste data is allocated in a _local_ variable in the frontend paste functions, passed directly to term_do_paste which now takes (buffer,length) parameters, and freed immediately afterwards. get_clip() is gone.
