Fix various issues in how %#T is handled:

- If precision is 0, don't print period followed by no digits. - If precision is 0 stop printing units as soon as possible (eg. if we have three years and five days and precision is 0 print only 3y5d). - If precision is not 0, print all units (eg. 3y0d0h0m0s.00). MFC after: 2 weeks

When reopening a stream backed by an open file descriptor, do not close

the existing file descriptor. Instead, let dup2() atomically close the old file descriptor when assigning the newly opened file to the same descriptor. This closes a race in a multithreaded application where a concurrent open() could allocate the existing file descriptor in between the calls to close() and dup2().
