Manage QUICStream instances without relying on quiche

[maskit]

quiche_conn_stream_init_application_data and quiche_conn_stream_application_data will be unavailable on next version of quiche. Actually I found there is a case that we cannot rely on them and I was going to stop using it.

After rerunning ./tools/build_h3_tools.sh I no longer see this issue. However, I was seeing this new problem:

Undefined symbols for architecture arm64:
  "_SecRandomCopyBytes", referenced from:
      ring::rand::darwin::fill::h44242773538e164c in libquiche.a(ring-2c63e41ea77c72de.ring.52c1a422d4e2ffc5-cgu.10.rcgu.o)
  "_kSecRandomDefault", referenced from:
      ring::rand::darwin::fill::h44242773538e164c in libquiche.a(ring-2c63e41ea77c72de.ring.52c1a422d4e2ffc5-cgu.10.rcgu.o)
ld: symbol(s) not found for architecture arm64

I was about to around this by setting my LDFLAGS with:
export LDFLAGS="-framework Security -framework Foundation"

I am using the Apple clang compiler:

-- CMAKE_CXX_COMPILER="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++"
-- CMAKE_C_COMPILER="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc"

We cannot close this issue. We need to modify our code so we do not use the removed functions.
