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.

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.

This copies the github.com/moby/buildkit/util/appcontext
package as an internal package. The appcontext package from
BuildKit was the only remaining dependency on BuildKit, and
while we may need some of its functionality, the implementation
is not correct for how it's used in docker/cli (so would need
a rewrite).
Moving a copy of the code into the docker/cli (but as internal
package to prevent others from depending on it) is a first step
in that process, and removes the circular dependency between
BuildKit and the CLi.

The BuildKit dockerignore package was migrated to 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.
