I'm pretty done with typing uefi_call_wrapper() and counting arguments
every time. Instead, just make the compiler error if we don't have
ms_abi. Also, make it so nothing can use uefi_call_wrapper() directly.

Also consistently name our status variable "efi_status" unless there's a
good reason not to, such as already having another one of those.

Originally, we check if the last 2 nodes in the device path are
IPv4()/Uri() or IPv6()/Uri() to determine whether httpboot is used or
not. However, since UEFI 2.7, the DNS node will be inserted between the
IP node and the URI node if the server provides the DNS server address.
This commit changes the matching rule to search IP node and URI node
and ignore any node between those two nodes.

This commit adds the basic support for HTTPBoot, i.e. to fetch
the next stage loader with the HTTP protocol.
It requires gnu-efi >= 3.0.3 to support the URI device path and
Ip4Config2 or Ip6Config protocol support in the UEFI implementation.
To build shim.efi with HTTPBoot support:
make ENABLE_HTTPBOOT=1 shim.efi
