Berthold Stoeger 152e6966c9 fix copy/paste of dive-site 
The copy/pasting of dive-sites was fundamentally broken in at least two
ways:

1) The dive-site pointer in struct dive was simply overwritten, which
   breaks internal consistency. Also, no dive-site changed signals where
   sent.

2) The copied dive-site was stored as a pointer in a struct dive. Thus,
   the user could copy a dive, then delete the dive-site and paste.
   This would lead to a dangling pointer and ultimately crash the
   application.

Fix this by storing the UUID of the dive-site, not a pointer.
To do that, don't store a copy of the dive, but collect all
the data in a `dive_paste_data` structure.
If the dive site has been deleted on paste, do nothing.
Send the appropriate signals on pasting.

The mobile version had an additional bug: It kept a pointer to the
dive to be copied, which might become stale by undo.
