[PATCH v2 0/9] efi_loader: capsule: improve capsule authentication support

[AKASHI Takahiro]

As I proposed and discussed in [1] and [2], I have made a couple of
improvements on the current implementation of capsule update in this
patch set.

* add signing feature to mkeficapsule
* add "--guid" option to mkeficapsule
* add man page of mkeficapsule
* add pytest for capsule authentication (on sandbox)

NOTE:
Due to Ilias's commit[3], we need to have a customized configuration
for sandbox to properly set up and run capsule authentication test.
See patch#5,#6 and #7.
