According to @aktau, the call to `mach_timebase_info` costs 90% of the
total execution time of `uv_hrtime()`. The result of the call is static
on all existing platforms, so there is no need in invoking it multiple
times.

We add a function called uv_loop_size which returns the size of
the loop. It is an additional function which complements
`uv_handle_size` and` uv_req_size` in order to provide full FFI
support.

- (README.md) The PYTHON environment variable should point to python.exe
not the python directory.
- (vcvars.bat) The PYTHON environment variable should be quoted on
expansion in case there's spaces in the path.
A correct barriers implementation blocks in uv_barrier_destroy() until
the last thread returns from uv_barrier_wait() so make the test more
rigorous by destroying the barrier straight away instead of first
joining the worker thread.

Add some basic doc comments to the uv_barrier_*() functions and document
the "serializer" return value from the previous commit.

Make uv_barrier_wait() return a boolean value indicating whether this
thread was the "serializer".
From `man pthread_barrier_wait`:
Upon successful completion, the pthread_barrier_wait() function
shall return PTHREAD_BARRIER_SERIAL_THREAD for a single (arbitrary)
thread synchronized at the barrier and zero for each of the other
threads.
Exposing that information from libuv is useful because it can make
cleanup significantly easier:
if (uv_barrier_wait(&barrier) > 0)
uv_barrier_destroy(&barrier);

Remove should shuffle items in both directions, not just down. It is
required, because `max` node could be not the actual maximum value in
the tree.

Only these functions will trigger an implicit binding of a UDP handle:
- uv_udp_send
- uv_udp_recv_start
- uv_udp_set_membership
All other functions will return UV_EBADF in case the socket was not
bound.
Note: currently the socket is created and bound at the same time. This
may change in the future.
If there is an error in the uv_read_cb, close the uv_stream_t
immediately instead of waiting until the uv_write_cb, and only close the
stream in after_write() if it hasn't been closed already.
If the handle was opened using `uv_udp_open` ift's possible that the
kernel doesn't fill in the msg_name field, so return NULL as the address
in that case.
