I did this

I noticed build failures on travis on current ngtcp2 builds. They build ngtcp2 from their git master and the failure is in the building of their example client.

In file included from client.cc:47:0:
client.h:35:23: fatal error: string_view: No such file or directory
compilation terminated.
Makefile:719: recipe for target 'client.o' failed
make[2]: *** [client.o] Error 1

I expected the following

The build to go green

Details

I asked @tatsuhiro-t about it in another channel and he responded like this:

It is in C++17 standard. Recent gcc/clang should work. I'll add configure option to build library only.

We can work on fixing the C++ in travis or just disable the example build for ngtcp2 (once support for that has landed). Disabling the example will be preferably anyway since it'll speed up the build and we don't use the example for anything!
