Subject: [PATCH] Support UEFI networking protocols
References: fate#320130, bsc#1015589, bsc#1076132
Patch-Mainline: no
V1:
* Add preliminary support of UEFI networking protocols
* Support UEFI HTTPS Boot
V2:
* Workaround http data access in firmware
* Fix DNS device path parsing for efinet device
* Relaxed UEFI Protocol requirement
* Support Intel OPA (Omni-Path Architecture) PXE Boot
V3:
* Fix bufio in calculating address of next_buf
* Check HTTP respond code
* Use HEAD request method to test before GET
* Finish HTTP transaction in one go
* Fix bsc#1076132
