Added an explicit type for the termios constants (#10266) 
Adds the `tcflag_t` type to the termios constants.
This is made to allow bitwise operations on the termios
constants without an integer cast, e.g.:

```zig
var raw = try std.os.tcgetattr(std.os.STDIN_FILENO);
raw.lflag &= std.os.linux.ECHO | std.os.linux.ICANON;
```
instead of

```zig
var raw = try std.os.tcgetattr(std.os.STDIN_FILENO);
raw.lflag &= ~@intCast(u32, std.os.linux.ECHO | std.os.linux.ICANON);
```

0714832c21 Fix test for io_uring link_timeout 
The old test "timeout_link_chain1" was ported from liburing test_timeout_link_chain1
509873c445/test/link-timeout.c (L539-L628)
However it turns out that both fails with EBADF (-9) on Linux kernel 5.4.

The this new test skips properly on Linux kernel 5.4
and passes on Linux kernel 5.11.

d7c770fb7f os: fix getrlimit/setrlimit test for MIPS 
This test can fail due to a fix in musl for 32 bit MIPS, where musl changes limits greater than -1UL/2 to RLIM_INFINITY.
See http://git.musl-libc.org/cgit/musl/commit/src/misc/getrlimit.c?id=8258014fd1e34e942a549c88c7e022a00445c352

Depending on the system where the test is run getrlimit can return
RLIM_INFINITY for example if RLIMIT_MEMLOCK is bigger than ~2GiB.

If that happens, the setrlimit call will fail with PermissionDenied.

008b0ec5e5 std.Thread.Mutex: change API to lock() and unlock() 
This is a breaking change. Before, usage looked like this:

```zig
const held = mutex.acquire();
defer held.release();
```

Now it looks like this:

```zig
mutex.lock();
defer mutex.unlock();
```

The `Held` type was an idea to make mutexes slightly safer by making it
more difficult to forget to release an aquired lock. However, this
ultimately caused more problems than it solved, when any data structures
needed to store a held mutex. Simplify everything by reducing the API
down to the primitives: lock() and unlock().

Closes #8051
Closes #8246
Closes #10105

            .exclude_kernel = true,

        },
    };
    const fd = try std.os.perf_event_open(&attr, 0, -1, -1, PERF.FLAG.FD_CLOEXEC);
    defer std.os.close(fd);

    _ = std.os.linux.ioctl(fd, PERF.EVENT_IOC.RESET, 0);
    _ = std.os.linux.ioctl(fd, PERF.EVENT_IOC.ENABLE, 0);

    std.debug.print("instruction count: {d}\n", .{result});
}

fn long() void {
    var i: usize = 0;
    while (i < 100000) : (i += 1) {}

1690b35770 std: Fix edge case in TLS tp calculation 
The TLS area may be located in the upper part of the address space and,
if the platform expects a constant offset to be applied, may make the tp
register calculation overflow.

Use +% instead of +, the overflow is harmless.

506f24cac2 Set the Storage socket sizes to be system defined 
Some systems (Solaris, OpenBSD, AIX) change their definitions of
sockaddr_storage to be larger than 128 bytes. This comment adds a new
constant in the `sockaddr` that defines the size for every system.
