2264fca03e fix regression on linux with kernel_timespec
I incorrectly assumed that __kernel_timespec was used when not linking
libc, however that is not the case. `std.os.timespec` is used both for
libc and non-libc cases. `__kernel_timespec` is a special struct that is
used only for io_uring.

a2ff3a13fe std, compiler-rt: remove test names where applicable
Tests with no names are executed when using `zig test` regardless of the
`--test-filter` used. Non-named tests should be used when simply
importing unit tests from another file. This allows `zig test` to find
all the appropriate tests, even when using `--test-filter`.

c05a20fc8c std: reorganization that allows new usingnamespace semantics
The proposal #9629 is now accepted, usingnamespace stays but no longer
puts identifiers in scope.

7f03cfe161 std.os: more reorganization efforts
* 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`

3deda15e21 std.os reorganization, avoiding usingnamespace
The main purpose of this branch is to explore avoiding the
`usingnamespace` feature of the zig language, specifically with regards
to `std.os` and related functionality.

If this experiment is successful, it will provide a data point on
whether or not it would be practical to entirely remove `usingnamespace`
from the language.

In this commit, `usingnamespace` has been completely eliminated from
the Linux x86_64 compilation path, aside from io_uring.

The behavior tests pass, however that's as far as this branch goes. It is
very breaking, and a lot more work is needed before it could be
considered mergeable. I wanted to put a pull requset up early so that
zig programmers have time to provide feedback.

This is progress towards closing #6600 since it clarifies where the
actual "owner" of each declaration is, and reduces the number of
different ways to import the same declarations.

One of the main organizational strategies used here is to do namespacing
with real namespaces (e.g. structs) rather than by having declarations
share a common prefix (the C strategy). It's no coincidence that
`usingnamespace` has similar semantics to `#include` and becomes much
less necessary when using proper namespaces.

d29871977f remove redundant license headers from zig standard library
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.

871f6343f4 Move iovec and log levels to bits/posix.zig
This lets only the OSes that uses them to import them, and removes
dependencies on bits.zig for the os/<os>/<arch>.zig files

d279a23c93 mips: fix syscall_pipe
Previously the fd parameter was ignored and so the result would not get
populated. Now it passes the fd pointer to the inline assembly so that
the results can be observed.

867ae506e3 std: Add syscall7 stub for Linux/MIPS
Some syscalls such as fadvise require an extra argument to comply with
the register pair alignment imposed by the ABI.

Wacky, isn't it?
