loader: add HTTP support using UEFI

Add support for an HTTP "network filesystem" using the UEFI's HTTP
stack.

This also supports HTTPS, but TianoCore EDK2 implementations currently
crash while fetching loader files.
Only IPv4 is supported at the moment. IPv6 support is planned for a
follow-up changeset.

Note that we include some headers from the TianoCore EDK II project in
stand/efi/include/Protocol verbatim, including links to the license instead
of including the full text because that's their preferred way of
communicating it, despite not being normal FreeBSD project practice.

The HTTP driver will queue a receive token to the underlying TCP instance. When data
is received in the underlying TCP instance, the data will be parsed and Token will
be populated with the response data. If the data received from the remote host
contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
(asynchronously) for more data to be sent from the remote host before signaling
Event in Token.
It is the responsibility of the caller to allocate a buffer for Body and specify the
size in BodyLength. If the remote host provides a response that contains a content
body, up to BodyLength bytes will be copied from the receive buffer into Body and
BodyLength will be updated with the amount of bytes received and copied to Body. This
allows the client to download a large file in chunks instead of into one contiguous
block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
token to underlying TCP instance. If data arrives in the receive buffer, up to
BodyLength bytes of data will be copied to Body. The HTTP driver will then update
BodyLength with the amount of bytes received and copied to Body.
If the HTTP driver does not have an open underlying TCP connection with the host
specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
an open TCP connection between client and host.

The successfully configured data is valid after system reset or power-off.
The DataSize is used to calculate the count of structure instances in the Data for some
DataType that multiple structure instances are allowed.
This function is always non-blocking. When setting some typeof configuration data, an
asynchronous process is invoked to check the correctness of the data, such as doing address conflict
detection on the manually set local IPv4 address. EFI_NOT_READY is returned immediately to
indicate that such an asynchronous process is invoked and the process is not finished yet. The caller
willing to get the result of the asynchronous process is required to call RegisterDataNotify()
to register an event on the specified configuration data. Once the event is signaled, the caller can call
GetData()to get back the configuration data in order to know the result. For other types of
configuration data that do not require an asynchronous configuration process, the result of the
operation is immediately returned.
