Experimental support for QEMU TCG (x86_64)

c2w experimentally integrates QEMU TCG on Wasm(emscripten), using QEMU Wasm. Multicore CPUs can also be enabled leveraging MTTCG(Multi-Threded TCG).

NOTE: Example of AArch64 container with QEMU TCG is available at ./../emscripten-aarch64

Example: x86_64 alpine on emscripten

$ make
$ mkdir -p /tmp/out-js4/htdocs
$ ./out/c2w --dockerfile=Dockerfile --assets=. --target-stage=js-qemu-amd64 alpine /tmp/out-js4/htdocs/
$ cp -R ./examples/emscripten-qemu-tcg/* /tmp/out-js4/
$ docker run --rm -p 8082:80 \
         -v "/tmp/out-js4/htdocs:/usr/local/apache2/htdocs/:ro" \
         -v "/tmp/out-js4/xterm-pty.conf:/usr/local/apache2/conf/extra/xterm-pty.conf:ro" \
         --entrypoint=/bin/sh httpd -c 'echo "Include conf/extra/xterm-pty.conf" >> /usr/local/apache2/conf/httpd.conf && httpd-foreground'

Then localhost:8082 serves the image.
