Without declaring EFIAPI for ERR_add_error_vdata, shim would crash
while verifying the loaded image.

It's annoying to find out we're not in SB mode over and over. Really it

Nobody should be deploying SHA-1. No hardware deploys it, and the rate
of change on https://en.wikipedia.org/wiki/SHA-1#Attacks is wildly
uninspiring.

Add SHA1 hash support and amend the code to make it easier to support
other SHA digests.

match_hash() requests the number of keys in a list and it was
mistakenly replaced with the size of the Mok node. This would
made MokManager to remove the whole Mok node instead of one
hash.

MokSize of the hash signature list includes the owner GUID,
so we should not add the 16bytes compensation.

When we made lib build with the correct CFLAGS, it inherited
-Werror=sign-compare, and I fixed up some parameters on
console_print_box() and console_print_box_at() to avoid sign comparison
errors.
The fixups were *completely wrong*, as some behavior relies on negative
values. So this fixes them in a completely different way, by casting
appropriately to signed types where we're doing comparisons.

Right now applications run by shim get our wrapper for Exit(), but it
doesn't do as much cleanup as it should - shim itself also exits, but
currently is not doing all the cleanup it should be doing.
This changes it so all of shim's cleanup is also performed.
Based on a patch and lots of review from Gary Lin.

Right now if shim_verify() sees secure_mode()==0, it exits with
EFI_SUCCESS, but accidentally leaves in_protocol=1. This means any
other call will have supressed error/warning messages.
That's wrong, so don't do it.

Don't run MokManager on any random error from start_image(second_stage);
only try it if it /is/ the second stage, or if start_image gave us
EFI_SECURITY_VIOLATION.

The wildcard support was introduced in objcopy since binutils 2.24.
However, objcopy < 2.24 never issues any warning message with the
wildcard and a faulty binary will be generated. This commit makes
the build failed as a notification for the usage of binutils < 2.24.

We depend on there being a .hash section in the binary, and that's not
the case on distributions that default to building with gnu-style ELF
hashes. Explicitly request sysv-style hashes in order to avoid building
broken binaries.
