Add support for GPG signature enforcement on booted
kernels and related blobs This can be used to implement a form of organization-controlled secure boot, whereby kernels may be loaded from a variety of sources but they will only boot if a valid signature file is found for each component, and only if the signature is listed in the /etc/pb-lockdown file. Signed-off-by: Timothy Pearson <tpearson@raptorengineering.com> Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com> (Minor build fixes and gpgme.m4, comment on secure boot in gpg.c)
