unix: make uv_shutdown() return UV_ENOTCONN

Return UV_ENOTCONN when the stream is not connected, not UV_EINVAL. Aligns
with uv-win.

unix: fix req cb / close cb invoke delay

Finalization of closed handles and associated requests was sometimes delayed
until an external event (network I/O, timeout, etc.) happened. This commit
addresses that.

sunos: uv_interface_addresses needlessly #ifdef'd out

Make ngx_queue_foreach() impl more explicit.

Avoids accidental overflow / truncation when it's used in 32 bits arithmetic.

requests aren't processed until the next event (I/O, timeout, etc.) happens.

Debugging tool, prints a list of active/all handles. Not actively exported.

windows: detect when GetCurrentDirectoryW returns more than MAX_PATH chars

This should never happen. However the CRT has a code path to deal
with this situation, so at least detect it when it happens and return
an error, instead of potentially opening a security hole.

unix: fix loop starvation under high network load

uv__read() and uv__udp_recvmsg() read incoming data in a loop. If data comes
in at high speeds, the kernel receive buffer never drains and said functions
never terminate, stalling the event loop indefinitely. Limit the number of
consecutive reads to 32 to stop that from happening.

The number 32 was chosen at random. Empirically, it seems to maintain a high
throughput while still making the event loop move forward at a reasonable pace.

Stop libev from entering the epoll_wait/kevent/port_getn/etc. syscall when
there are no active handles left, that will block indefinitely.
