0333ff4476 stage2: make error{} the same size as anyerror
Having `error{}` be a zero bit type causes issues when it interracts
with empty inferred error sets which are the same size as `anyerror`.

zig fmt: remove trailing whitespace on doc comments
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.

compress: add a deflate compressor
Replaces the inflate API from `inflateStream(reader: anytype, window_slice: []u8)` to
`decompressor(allocator: mem.Allocator, reader: anytype, dictionary: ?[]const u8)` and
`compressor(allocator: mem.Allocator, writer: anytype, options: CompressorOptions)`

compress: remove sha256 checks from tests
Read bytes to check expected values instead of reading and hashing them.
Hashing is a waste of time when we can just read and compare.
This also removes a dependency on std.crypto.hash.sha2.Sha256 for tests.

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.

13068da43e x/os, x/net: re-approach Address, rename namespace TCP -> tcp
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.

41f244bd2f std: Make the DEFLATE decompression routine 3x faster
A profiler run showed that the main bottleneck was the naive decoding of
the Huffman codes, replacing it with a nice trick borrowed by Zlib gave
a substantial speedup.
Replacing a `%` with a `and (mask-1)` gave another significant
improvement (yay for low hanging fruits).

A few numbers obtained by decompressing a 22M file:

Before:
```
./decompress  2,39s user 0,00s system 99% cpu 2,400 total
```

After:
```
./decompress  0,79s user 0,00s system 99% cpu 0,798 total
