James Muir 86db958835 demos: tidy up makefiles, fix warnings
Update makefiles so that consistent patterns are used.  Object files
are compiled from source using an implicit rule (but using our
CFLAGS); for linking, we give an explicit rule.  Ensure that "make
test" works in each subdirectory (even if it does not actually run any
applications).  The top-level demo makefile now works.

The makefiles are not make-agnostic.  e.g. they use the variable $(RM)
in "clean" recipes, which is defined in gnu-make but may not be
defined in others.

Part of #17806

Testing:

  $ cd demo
  $ make test

HTTP/3 Demo using OpenSSL QUIC and nghttp3

This is a simple demo of how to use HTTP/3 with OpenSSL QUIC using the HTTP/3 library “nghttp3”.

The demo is structured into two parts:

  • an adaptation layer which binds nghttp3 to OpenSSL's QUIC implementation (ossl-nghttp3.c);
  • a simple application which makes an HTTP/3 request using this adaptation layer (ossl-nghttp3-demo.c).

The Makefile in this directory can be used to build the demo on *nix-style systems. You will need the nghttp3 library and header file. On Ubuntu, these can be obtained by installing the package libnghttp3-dev.

Running the Demo

Depending on your system configuration it may be necessary to set the SSL_CERT_FILE or SSL_CERT_DIR environment variables to a location where trusted root CA certificates can be found.

After building by running make, run ./ossl-nghttp3-demo with a hostname and port as the sole argument:

$ make
$ LD_LIBRARY_PATH=../.. ./ossl-nghttp3-demo www.google.com:443

The demo produces the HTTP response headers in textual form as output followed by the response body.
