This patch adjusts the exit code for a child process to be a u8. Since
the WEXITSTATUS macro returns the lower eight bits, it's safe to assume
that we can truncate the returned u32.
`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.

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.
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 `Socket` abstraction was refactored to only comprise of methods that
can be generically used/applied to all socket domains and protocols.
A more comprehensive IPv4/IPv6 module derived from @LemonBoy's earlier
work was implemented under `std.x.os.IPv4` and `std.x.os.IPv6`. Using
this module, one can then combine them together into a union for example
in order to optimize memory usage when dealing with socket addresses.
A `TCP.Client` and `TCP.Listener` abstraction is introduced that is one
layer over the `Socket` abstraction, which isolates methods that can
only be applied to a "client socket" and a "listening socket". All prior
tests from the `Socket` abstraction, which all previously operated
assuming the socket is operating via. TCP/IP, were moved. All TCP socket
options were also moved into the `TCP.Client` and `TCP.Listener`
abstractions respectively away from the `Socket` abstraction.
Some additional socket options from @LemonBoy's prior PR for Darwin were
also moved in (i.e. SIGNOPIPE).
* `comptime const` is redundant
* don't use `extern enum`; specify a tag type.
`extern enum` is only when you need tags to alias. But aliasing tags
is a smell. I will be making a proposal shortly to remove `extern enum`
from the language.
* there is no such thing as `packed enum`.
* instead of `catch |_|`, omit the capture entirely.
* unused function definition with missing parameter name
* using `try` outside of a function or test
Xnu's sigaction() only supports fetching a limited set of sa_flags, test
SA_SIGINFO instead of SA_RESETHAND as that's supported everywhere.
Add another check to make sure SA_RESETHAND works.

There's no guarantee for the kernel definition to be ABI compatible with
the libc one (and vice versa).
There's also no guarantee of ABI compatibility between musl/glibc.
Fun, isn't it?
On Darwin, according to the man pages for setrlimit(), when adjusting
max number of open fds, the reported hard max by getrlimit() is only
theoretical, while the actual maximum, set in the kernel, is hardcoded
in the header file. Therefore, the reported max has to be adjusted
as `min(OPEN_MAX, lim.max)`.

- correct uid_t from i32 to u32 on linux
- define uid_t and gid_t for OSes missing definitions
- use uid_t/gid_t instead of plain u32s throughout std.os
Remove the constants that assume a base unit in favor of explicit
x_per_y constants.
nanosecond calendar timestamps now use i128 for the type. This affects
fs.File.Stat, std.time.nanoTimestamp, and fs.File.updateTimes.
calendar timestamps are now signed, because the value can be less than
the epoch (the user can set their computer time to whatever they wish).
implement std.os.clock_gettime for Windows when clock id is
CLOCK_CALENDAR.
`flock` locks based on the file handle, instead of the process id.
This brings the file locking on unix based systems closer to file
locking on Windows.
* `zig test` gainst `--test-evented-io` parameter and gains the ability
to seamlessly run async tests.
* `std.ChildProcess` opens its child process pipe with O_NONBLOCK when
using evented I/O
* `std.io.getStdErr()` gives a File that is blocking even in evented
I/O mode.
* Delete `std.event.fs`. The functionality is now merged into `std.fs`
and async file system access (using a dedicated thread) is
automatically handled.
* `std.fs.File` can be configured to specify whether its handle is
expected to block, and whether that is OK to block even when in
async I/O mode. This makes async I/O work correctly for e.g. the
file system as well as network.
* `std.fs.File` has some deprecated functions removed.
* Missing readv,writev,pread,pwrite,preadv,pwritev functions are added
to `std.os` and `std.fs.File`. They are all integrated with async
I/O.
* `std.fs.Watch` is still bit rotted and needs to be audited in light
of the new async/await syntax.
* `std.io.OutStream` integrates with async I/O
* linked list nodes in the std lib have default `null` values for
`prev` and `next`.
* Windows async I/O integration is enabled for reading/writing file
handles.
* Added `std.os.mode_t`. Integer sizes need to be audited.
* Fixed#4403 which was causing compiler to crash.
This is working towards:
./zig test ../test/stage1/behavior.zig --test-evented-io
Which does not successfully build yet. I'd like to enable behavioral
tests and std lib tests with --test-evented-io in the test matrix in the
future, to prevent regressions.
* Delete `std.net.TmpWinAddr`. I don't think that was ever meant to
be a real thing.
* Delete `std.net.OsAddress`. This abstraction was not helpful.
* Rename `std.net.Address` to `std.net.IpAddress`. It is now an extern
union of IPv4 and IPv6 addresses.
* Move `std.net.parseIp4` and `std.net.parseIp6` to the
`std.net.IpAddress` namespace. They now return `IpAddress` instead of
`u32` and `std.net.Ip6Addr`, which is deleted.
* Add `std.net.IpAddress.parse` which accepts a port and parses either
an IPv4 or IPv6 address.
* Add `std.net.IpAddress.parseExpectingFamily` which additionally
accepts a `family` parameter.
* `std.net.IpAddress.initIp4` and `std.net.IpAddress.initIp6` are
improved to directly take the address fields instead of a weird
in-between type.
* `std.net.IpAddress.port` is renamed to `std.net.IpAddress.getPort`.
* Added `std.net.IpAddress.setPort`.
* `os.sockaddr` struct on all targets is improved to match the
corresponding system struct. Previously I had made it a union of
sockaddr_in, sockaddr_in6, and sockaddr_un. The new abstraction for
this is now `std.net.IpAddress`.
* `os.sockaddr` and related bits are added for Windows.
* `os.sockaddr` and related bits now have the `zero` fields default
to zero initialization, and `len` fields default to the correct size.
This is enough to abstract the differences across targets, and so
no more switch on the target OS is needed in `std.net.IpAddress`.
* Add the missing `os.sockaddr_un` on FreeBSD and NetBSD.
* `std.net.IpAddress.initPosix` now takes a pointer to `os.sockaddr`.
