1.10.1

Latest changes

- 1.10.1
- [BUGFIX]  process connections after each batch of packets is read
  This avoids a problem of accumulating a very large list of packets
  (possible when speeds are high and socket's receive buffer is large)
  and processing it all at once.
- If glibc is older than 2.17, link with rt.  This is necessary for
  clock_getres(2).
- Add version macros to lsquic.h; remove unnecessary includes.
