bugfix: avoid use-after-free after receiveuntil iterator GC.

Detach the compiled pattern from the upstream when finalizing the read
side, and clear the upstream reference to the pattern. This prevents
socket finalization from accessing a pattern already freed by Lua GC.

Port the fix and regression test from lua-nginx-module commit
20acb75174d3f6ce3578cb96070218fd4466ce43. The test verifies that the
iterator is collected after a read error before closing the socket.

Validated with t/066-socket-receiveuntil.t and
t/084-inclusive-receiveuntil.t: all 188 assertions passed.

bugfix: clean child coroutine ops when killing uthreads.

Cancel descendant coroutine operations before deleting killed user threads so delayed cosocket events cannot resume collected Lua states.

bumped stream-lua-nginx-module to v0.0.20.

bugfix: ngx.req.start_time() corrupted nginx's cached time on freenginx.

ngx_stream_lua_ffi_req_start_time() (the freenginx branch) called
ngx_timeofday() and then mutated *tp directly. ngx_timeofday() returns
a pointer to ngx_cached_time, the global time cache shared by the
entire worker, so the subtraction of (ngx_current_msec -
r->session->start_time) silently rewound the clock for every
subsequent ngx_timeofday() reader within the same event-loop tick
(log timestamps, timer deadlines, etc.).

Copy the cached time into a local ngx_time_t and do the arithmetic
there.

Mirrors the fix in lua-nginx-module.

bugfix: use NGX_SOCKADDR_STRLEN for portability on Windows & FreeBSD

NGX_UNIX_ADDRSTRLEN is only defined when Unix domain sockets are
supported, which excludes Windows. Use NGX_SOCKADDR_STRLEN instead
for the address text buffer in cosocket error logging, which is
defined on all platforms.

tests: fixed t/062-count.t.

bumped ngx_stream_lua_version to 19.

bugfix: supress clang warning.
