don't dereference NULL after failed strdup

Most of these are obvious NULL-deref bug fixes, for example,
the ones in these files:

Add HTTP protocol using curl v6

Currently Qemu can read from posix I/O and NBD. This patch adds a
third protocol to the game: HTTP.

In certain situations it can be useful to access HTTP data directly,
for example if you want to try out an http provided OS image, but...
