iPXE used Uri() device path nodes. So we should support them in the
device path to text protocol.

In the commit c982874e930d ("efi_loader: refactor
efi_setup_loaded_image()"), setjmp-related definitions were moved to
efi_loaded_image_obj in efi_loader.h. So setjmp.h is no longer
refererenced in efi_api.h.

This also fixes some error when efi_api.h will be included in
mkeficapsule.c.

The ESRT is initialised during efi_init_objlist after
efi_initialize_system_table().

The ESRT is recreated from scratch at the following events:
- successful UpdateCapsule;
- FMP instance install.

The code ensures that every ESRT entry has a unique fw_class value.

Limitations:
- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left
undefined. Setting these values will require a per-platform function
that returns the image_type/flags as a function of the image fw_class.
