[PATCH 0/2] Add ESRT and test ESRT creation

The following 2 commits add the ESRT and provide a test of the
functionality.

The first commit adds the ESRT as defined in the UEFI 2.8 specification.
An empty ESRT is created during the execution of the efi_init_obj_list().
The ESRT is updated when:
  1) a FMP protocol is installed in the system: this will add the
corresponding entries to the ESRT.
  2) a capsule is installed via UpdateCapsule: this should update
entries already present in the ESRT.

This implementation of the ESRT creation takes input from FMP only.
It is assumed that the FMP will maintain the following values across
reboot:
 - LastAttemptVersion.
 - LastAttemptStatus.


The second commit enables testing the ESRT creation in the sandbox
platfrom. The test executes from the u-boot shell with "ut lib".

Note: I've removed the RFC tag that was previously used to post this
patch.

Patch v1:
- reworked the ESRT creation code, allowing table to resize as
FMPs are installed.
- registered a callback for the FMP protocol install.
- Created a unit test running on the sandbox platform.
