Ultimate flexibility, just be sure to destroy the correct amount of
information when looking at them.

* Uncouple std.http.ChunkParser from protocol.zig
* Fix receiveHead not passing leftover buffer through the header parser.
* Fix content-length read streaming
This implementation handles the final chunk length correctly rather than
"hoping" that the buffer already contains \r\n.

Mainly, this removes the poorly named `wait`, `send`, `finish`
functions, which all operated on the same "Response" object, which was
actually being used as the request.
Now, it looks like this:
1. std.net.Server.accept() gives you a std.net.Server.Connection
2. std.http.Server.init() with the connection
3. Server.receiveHead() gives you a Request
4. Request.reader() gives you a body reader
5. Request.respond() is a one-shot, or Request.respondStreaming() creates
a Response
6. Response.writer() gives you a body writer
7. Response.end() finishes the response; Response.endChunked() allows
passing response trailers.
In other words, the type system now guides the API user down the correct
path.
receiveHead allows extra bytes to be read into the read buffer, and then
will reuse those bytes for the body or the next request upon connection
reuse.
respond(), the one-shot function, will send the entire response in one
syscall.
Streaming response bodies no longer wastefully wraps every call to write
with a chunk header and trailer; instead it only sends the HTTP chunk
wrapper when flushing. This means the user can still control when it
happens but it also does not add unnecessary chunks.
Empirically, in my example project that uses this API, the usage code is
significantly less noisy, it has less error handling while handling
errors more correctly, it's more obvious what is happening, and it is
syscall-optimal.
Additionally:
* Uncouple std.http.HeadParser from protocol.zig
* Delete std.Server.Connection; use std.net.Server.Connection instead.
- The API user supplies the read buffer when initializing the
http.Server, and it is used for the HTTP head as well as a buffer
for reading the body into.
* Replace and document the State enum. No longer is there both "start"
and "first".

* add API for iterating over custom HTTP headers
* remove `trailing` flag from std.http.Client.parse. Instead, simply
don't call parse() for trailers.
* fix the logic inside that parse() function. it was using wrong std.mem
functions, ignoring malformed data, and returned errors on dead
branches.
* simplify logic inside wait()
* fix HeadersParser not dropping the 2 read bytes of \r\n after a
chunked transfer
* move the trailers test to be a std lib unit test and make it pass

This reverts commit 42be972a72c86b32ad8403d082ab42763c6facec.
Using a bit to distinguish between headers and trailers is fine. It was
just named and documented poorly.
|

This is a state machine that already has a `state` field. No need to
additionally store "done" - it just makes things unnecessarily
complicated and buggy.
|
|
The buffer for HTTP headers is now always provided via a static buffer.
As a consequence, OutOfMemory is no longer a member of the read() error
set, and the API and implementation of Client and Server are simplified.
error.HttpHeadersExceededSizeLimit is renamed to
error.HttpHeadersOversize.

The function returns the vector length, not the byte size of the vector or the bit size of individual elements. This distinction is very important and some usages of this function in the stdlib operated under these incorrect assumptions.

Let's take this breaking change opportunity to fix the style of this
enum.

Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change

fix for 32bit arches
curate error sets for api facing functions, expose raw errors in client.last_error
fix bugged dependency loop, disable protocol tests (needs mocking)
add separate mutex for bundle rescan

through upgrades

* extract http protocol into protocol.zig, as it is shared between client and server
* coalesce Request and Response back into Client.zig, they don't contain
any large chunks of code anymore
* http.Server is implemented as basic as possible, a simple example below:
```zig
fn handler(res: *Server.Response) !void {
while (true) {
defer res.reset();
try res.waitForCompleteHead();
res.headers.transfer_encoding = .{ .content_length = 14 };
res.headers.connection = res.request.headers.connection;
try res.sendResponseHead();
_ = try res.write("Hello, World!\n");
if (res.connection.closing) break;
}
}
pub fn main() !void {
var server = Server.init(std.heap.page_allocator, .{ .reuse_address = true });
defer server.deinit();
try server.listen(try net.Address.parseIp("127.0.0.1", 8080));
while (true) {
const res = try server.accept(.{ .dynamic = 8192 });
const thread = try std.Thread.spawn(.{}, handler, .{res});
thread.detach();
}
}
```
