The Linux kernel suppresses some ICMP error messages by default for UDP
sockets. This commit sets IP_RECVERR/IPV6_RECVERR on the socket to
enable full ICMP error reporting, hopefully resulting in faster failover
to working name servers.

ZOSLIB uses `argv[0]` to determine the exepath. So it is necessary to
use an implementation of proctitle that does not modify `argv[0]`. Since
there is currently no support for process titles on z/OS, the custom
proctitle implementation simply stores the desired title in memory.
This resolves failure in tests `get_currentexe` and `process_title` on
z/OS.

On z/OS, `execvp()` does not set the environment for child process from

This commit introduces ZOSLIB for z/OS, which is a C/C++ library that
implements additional POSIX APIs not available in the LE C Runtime
Library, and provides API for EBCDIC <-> ASCII conversion. This library
requires the linker to be set to CXX when building for z/OS. ZOSLIB is
designed to be installed separately, and then linked to libuv with the
`-DZOSLIB_DIR` option.

Applications running on hardened runtime based on Chromium/Electron
create mmap regions using MAP_JIT flag. With macOS Big Sur the fork()
calls done by uv_spawn have become slow. This is because fork() seems
to physically copy all JIT memory regions (no-copy-on-write). On
previous OS, these regions weren't accessible at all in the forked
process, explaining the regression.
The fix is to use posix_spawn() on macOS. This spawns a new process
directly, without copying any memory mappings.
Note that fork() is still used on earlier versions of macOS if the
necessary posix_spawn() platform-specific extensions are not available.

Consider the following scenario:
uv_poll_init(loop, poll, fd);
uv_poll_start(poll, UV_READABLE, cb);
// the cb gets invoked etc.
uv_poll_stop(poll);
close(fd);
fd = allocate_new_socket(); // allocate_new_socket() is assigned the same fd by "bad luck" from the OS
// some time later:
uv_poll_init(loop, otherpoll, fd);
uv_poll_start(otherpoll, UV_READABLE, cb);
uv_close(poll); // uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.
According to documentation, "however the fd can be safely closed
immediately after a call to uv_poll_stop() or uv_close()."
Though, in this scenario, we close()'d our file descriptor, and by
bad luck we got the same file descriptor again and register a new
handle for it and start polling.
Previously that would lead to an assertion failure, if we were to
properly free the original handle via uv_close().
This commit fixes that by moving the check whether a only a single
poll handle is active to uv_poll_start() instead of the stopping
routines.

`uv_fs_utime()` and `uv_fs_futime()` receive the timestamp as
a `double` and then convert it to `struct timeval` or `struct timespec`
where necessary but the calculation for the sub-second part exhibited
rounding errors for dates in the deep past or the far-flung future,
causing the timestamps to be off by sometimes over half a second on
unix, or to be reinterpreted as unsigned and end up off by more than
just sign but many also decades.
