server: prohibit more than MaxConcurrentStreams handlers from running at once
(CVE-2023-44487).
In addition to this change, applications should ensure they do not leave running
tasks behind related to the RPC before returning from method handlers, or should
enforce appropriate limits on any such work.

While updating the docker/docker dependency in BuildKit, I noticed that the
dependency tree showed _two_ separate versions of the semconv package;
BuildKit and containerd were using the v1.17.0 version and docker/docker was
using v1.7.0.
This patch updates the version we use to align with BuildKit and containerd.

This fixes the same CVE as go1.21.3 and go1.20.10;
- net/http: rapid stream resets can cause excessive work
A malicious HTTP/2 client which rapidly creates requests and
immediately resets them can cause excessive server resource consumption.
While the total number of requests is bounded to the
http2.Server.MaxConcurrentStreams setting, resetting an in-progress
request allows the attacker to create a new request while the existing
one is still executing.
HTTP/2 servers now bound the number of simultaneously executing
handler goroutines to the stream concurrency limit. New requests
arriving when at the limit (which can only happen after the client
has reset an existing, in-flight request) will be queued until a
handler exits. If the request queue grows too large, the server
will terminate the connection.
This issue is also fixed in golang.org/x/net/http2 v0.17.0,
for users manually configuring HTTP/2.
The default stream concurrency limit is 250 streams (requests)
per HTTP/2 connection. This value may be adjusted using the
golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams
setting and the ConfigureServer function.
This is CVE-2023-39325 and Go issue https://go.dev/issue/63417.
This is also tracked by CVE-2023-44487.

The DeepEqual ignore required in the daemon tests is a bit ugly, but it
works given the new protoc output.
We also have to ignore lints related to schema1 deprecations; these do
not apply as we must continue to support this schema version.

This uses otel standard environment variables to configure tracing in
the daemon.
It also adds support for propagating trace contexts in the client and
reading those from the API server.

for details on otel environment variables.

The BuildKit dockerignore package was integrated in the patternmatcher
repository / module. This patch updates our uses of the BuildKit package
with its new location.
A small local change was made to keep the format of the existing error message,
because the "ignorefile" package is slightly more agnostic in that respect
and doesn't include ".dockerignore" in the error message.
