eficonfig_select_file_handler() is commonly used to select the file. eficonfig_display_select_file_option() intends to add the additional menu mainly to clear the selected file information. eficonfig_display_select_file_option() is not necessary for the file selection process, so it should be outside of eficonfig_select_file_handler().

This commit adds the menu-driven interface to show and delete the signature database.

EFI Signature Lists can contain the multiple signature entries, this menu can delete the indivisual entry.

If the PK is enrolled and UEFI Secure Boot is in User Mode or Deployed Mode, user can not delete the existing signature lists since the signature lists must be signed by KEK or PK but signing information is not stored in the signature database.

To delete PK, user needs to enroll the new key with an empty value and this new key must be signed with the old PK.

Signed-off-by: Masahisa Kojima masahisa.kojima@linaro.org --- No change since v2

Changes in v2: - integrate show and delete signature database menu - add confirmation message before delete - add function comment
