Cros-checked with bpf.h of kernel 5.12.9.

`msghdr` and `msghdr_const` definitions have been added back the way
they were in std.os. std.os.sendmsg has also been modified to accept a
msghdr_const again to ensure backwards-compatibility with this PR.
Underneath the hood, std.os.sendmsg will @ptrCast the provided
msghdr_const into a std.x.os.Socket.Message.
`sockaddr_storage` definitions have been added back the way they were in
std.os, except that it now simply aliases
std.x.os.Socket.Address.Native.Storage as all of
std.x.os.Socket.Address.Native.Storage's fields are equivalent to the
fields that were previously defined for std.x.os.bits.sockaddr_storage.
std.x.os.Socket.sendMessage now no longer is a stub that aliases
std.os.sendmsg, but instead calls and handles
errors from std.os.system.sendmsg directly.
Addresses feedback to urge backwards compatibility from @andrewrk.

Cross-platform versions of msghdr, sendmsg, recvmsg, linger, and iovec
were provided based on findings from glibc, musl, and Microsoft's
documentation.
Implemented initial Reactor interface for epoll (linux) which wraps
around I/O reactor subsystems such as epoll, kqueue, select, etc. across
different platforms. The Reactor interface allows for driving async I/O
in Zig applications.
A test was added for the Reactor interface to drive a TCP
client/listener socket pair.
A greatest-common-subset of possible socket initialization flags (close
socket on exec syscalls, initialize socket to be non-blocking) were
implemented.
A test was added for using sendmsg/recvmsg syscalls across different
platforms for a TCP client/listener socket pair.

All other uses of `ws2_32.socklen_t` in windows.zig casts the value to an i32. `recvfrom` should do so as well; it currently errors out with `expected type '?*i32', found '?*u32'`.

- more support for linux, android, freebsd, netbsd, openbsd, dragonfly
- centralize musl utils; musl logic is no longer intertwined with csu
- fix musl compilation to build crti/crtn for full archs list
- fix openbsd to support `zig build-lib -dynamic`
- initial dragonfly linking success (with a warning)
ancillary:
- fix emutls (openbsd) tests to use `try`

When WSASocketW gets WSANOTINITIALISED, now it will lock a mutex to
safely call WSAStartup and then try again one time.
This implementation:
* Does not use recursion
* Contains a detailed doc comment explaining why things are how they are
* Is careful about which errors are surfaced in the respective error
sets. `std.os.socket` intentionally does not have "not initialised"
as one of the possible errors.
|
|
|
|
This replaces callconv(.Inline) with the more idiomatic inline keyword.

There are also some regressed std.fmt tests here and I haven't figured
out what's wrong yet.

- this one might be problematic; start.zig looks for `main` in the
root source file, not `_main`. Not sure why there is an underscore
there in master branch.

Mainly I wanted Jakub's new macOS code for respecting stack size, since
we now depend on it for debug builds able to pass one of the test cases
for recursive comptime function calls with `@setEvalBranchQuota`.
The conflicts were all trivial.

This is mostly meant to detect the current and future AArch64 core types
as the x86 part is already taken care of with OS-independent machinery.

- netbsd, dragonly: use sysctlbyname
- openbsd: use sysctl
- updated default semver ranges

The kernel interface expects the offset as a low+high pair even on BE
systems.
|
|
|
|
Let's follow the libc/kernel convention and use an i64 for offsets, we
bitcast as needed and avoid the useless conditional casts.

Implement loading Winsock extensions.
Add missing Winsock extension GUID's.
Implement readVectorized() for POSIX sockets and
readVectorized() / writeVectorized() for Windows
sockets.
Inverse how mixins are used to implement platform-independent syscalls
for the std.x.os.Socket abstraction. This cleans up the API as suggested
by @komuw.

Add missing constants to ws2_32 such as SIO_BASE_HANDLE.
Made all declared constants in ws2_32 comptime_int, and fixed a few
broken constants (i.e. GUID's).
Fixed a few syscalls not having callconv(WINAPI) in ws2_32.
Fixed a typo in std.x.net.tcp.Client.
Removed unnecessary @alignCast's for socket addresses in
std.x.net.Socket.
Added a warning on using timeout methods for std.x.net.Socket.
Fixed compilation error spotted by CI in std.os that references
std.os.windows.ws2_32.SD_RECEIVE.
Renamed std.x.os.Socket.setOption()'s parameter `name: u32` to `code:
u32`.

Socket I/O methods such as read, readv, write, writev, send, recv,
sendmsg, recvmsg have been generalized to read(buf, flags), write(buf,
flags), readVectorized(vectors, flags), and writeVectorized(vectors,
flags). There is still some work left to be done abstracting both
readVectorized and writeVectorized properly across platforms, which is
work to be done in a future PR.
Support for setting the linger timeout of a socket, querying the remote
address of a socket, setting whether or not keep-alive messages are to
be sent through a connection-oriented socket periodically depending on
host operating system settings has been added.
`std.io.Reader` and `std.io.Writer` wrappers around `Socket` has been
implemented, which wrap around Socket.read(buf, flags) and
Socket.write(buf, flags). Both wrappers may be provided flags which are
passed to Socket.read / Socket.write accordingly.
Cross-platform support for `getpeername()` has been implemented.
Windows support for the new `std.x.os.Socket` has been implemented. To
accomplish this, a full refactor of `std.os.windows.ws2_32` has been
done to supply any missing definitions and constants based on
auto-generated Windows syscall bindings by @marler8997.
`std.x.net.TCP.Listener.setQuickACK` has been moved to
`std.x.net.TCP.Client.setQuickACK`.
Windows support for resolving the scope ID of an interface name
specified in an IPv6 address has been provided.
`sockaddr_storage` definitions have been provided for Windows, Linux,
and Darwin. `sockaddr_storage` is used to allocate space before any
socket addresses are queried via. calls such as accept(), getsockname(),
and getpeername().
Zig-friendly wrappers for GetQueuedCompletionStatusEx(), getpeername(),
SetConsoleCtrlHandler(), SetFileCompletionNotificationModes() syscalls
on Windows have been provided.
Socket.setOption() was provided to set the value of a socket option in
place of os.setsockopt. Socket.getOption() will be provided in a future
PR.
There is still further work to be done regarding querying socket option
values on Windows, which is to be done in a subsequent PR.

The system `stat` structure includes padding, and, on some
operating systems such as all BSDs, "spare" bytes at the end.
We can't reliably compare two `Stat` values if these are
uninitialized, while being later compared.
This is what was causing the `fstatat` test to fail on FreeBSD
since the update to LLVM 12. It was previously only passing by
accident.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
