strings (#13526)
* Export invalidFmtErr
To allow consistent use of "invalid format string" compile error
response for badly formatted format strings.
See https://github.com/ziglang/zig/pull/13489#issuecomment-1311759340.
* Replace format compile errors with invalidFmtErr
- Provides more consistent compile errors.
- Gives user info about the type of the badly formated value.
* Rename invalidFmtErr as invalidFmtError
For consistency. Zig seems to use “Error” more often than “Err”.
* std: add invalid format string checks to remaining custom formatters
* pass reference-trace to comp when building build file; fix checkobjectstep

Add Seccomp bits for linux

Fixes #11353
The renderer treats comments and doc comments differently since doc
comments are parsed into the Ast. This commit adds a check after getting
the text for the doc comment and trims whitespace at the end before
rendering.
The `a = 0,` in the test is here to avoid a ParseError while parsing the
test.

This library contains:
- The global constants as used by C code.
- An Insn struct that implements can generate all the BPF instructions.
- A simple BPF virtual machine implementation that can be used for
testing programs. This has complete code-coverage and has been
extensively fuzzed.

Extract existing constants to do with TCP socket options into a 'TCP'
namespace.
Export 'MSG' and 'TCP' from std.os.{linux, windows} into std.c.
Fix compile errors to do with std.x.os.Socket methods related to setting
TCP socket options.
Handle errors in the case that an interface could not be resolved in an
IPv6 address on Windows. Tested using Wine with the loopback interface
disabled.
Have all instantiations of std.x.os.Socket on Windows instantiate an
overlapped socket descriptor. Fixes the '1ms read timeout' test in
std.x.net.tcp.Client. The test would previously deadlock, as read
timeouts only apply to overlapped sockets.
Windows documentation by default recommends that most instantiations of
sockets on Windows be overlapped sockets (s.t. they may operate in both
blocking or nonblocking mode when operated with WSA* syscalls). Refer to
the documentation for WSASocketA for more info.

Also move some usingnamespace test cases from compare_output to
behavior.

* std lib tests are passing on x86_64-linux with and without -lc
* stage2 is building from source on x86_64-linux
* down to 38 remaining uses of `usingnamespace`

We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.

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.

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.

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`.

Only allow SOCK_STREAM (std.x.net.tcp.Client) sockets to have wrappers
for std.io.Reader and std.io.Writer provided, instead of Socket's in
general.

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.

On OpenBSD, connecting to a newly-allocated port on an unspecified IPv4
host address causes EINVAL. This was found by @mikdusan when running TCP
tests on OpenBSD.
This commit fixes TCP tests on OpenBSD by having all tests that allocate
a new host-port pair to have the host IPv4/IPv6 address point to the
host's loopback adapter (on localhost).

Generalize `tcp.Address` into `ip.Address` given that multiple transport
protocols apart from TCP (i.e. UDP) operate solely over IP.

Address comments from @ifreund and @MasterQ32 to address unsafeness and
ergonomics of the `Address` API.
Rename the `TCP` namespace to `tcp` as it does not contain any
top-level fields.
Fix missing reference to `sockaddr` which was identified by @kprotty in
os/bits/linux/arm64.zig.

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).
