44e3ee8a2a I/O vector helpers (Avi Kivity) 
In general, it is not possible to predict the size of of an I/O vector since
a contiguous guest region may map to a disconiguous host region.  Add some
helpers to manage I/O vector growth.

793a10a2d4 Revert r5532, r5536 and a piece of r5531. 
The use of strncat and strndup was correct, pstrcpy and pstrdup wasn't.
I'll try to restore building on non-gnu OSes in a later commit.
