90c2ae5de2 feat: use the MCExtractor DB as the reference for the microcode versions
Use platomav's MCExtractor DB as the reference to decide whether our CPU microcode is the latest or not.
We have a builtin version of the DB in the script, but an updated version can be fetched and stored locally with --update-mcedb

53d6a44754 Fix detection of CVE-2018-3615 (L1TF_SGX) (#253)
* Add another location of Arch Linux ARM kernel

* Fix detection of CVE-2018-3615

We change the value of variantl1tf in the line directly before so its
value will never be "immune". Instead we can directly use the value of
variantl1tf to initialize variantl1tf_sgx.

fbbb19f244 Fix cases where a CPU ucode version is not found in $procfs/cpuinfo. (#246)
* Fix cases where a CPU ucode version is not found in $procfs/cpuinfo.

When running whithin a virtual machine, it seems like $procfs/cpuinfo doesn't contain
a 'microcode' line, which triggers a script runtime error.
Fall back to '0x0' in this case, as other part of the script seems to already this
as a default value anyway.

* Double quote to prevent globbing and word splitting.

349d77b3b6 Fix kernel detection when /lib/kernel exists on a distro (#252)
Commit b48b2177b7 ("feat: Add Clear Linux Distro (#244)") broke kernel
detection for distros using that directory for other purposes than
storing the kernel image.

Example:
 # pacman -Qo /lib/kernel
/usr/lib/kernel/ is owned by mkinitcpio 24-2
/usr/lib/kernel/ is owned by systemd 239.2-1

* Cortex A8 Vulnerable

Arm Cortex A8 is vulnerable to variants 1 & 2  (https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability)

Part number is 0xc08 (https://developer.arm.com/docs/ddi0344/b/system-control-coprocessor/system-control-coprocessorregisters/c0-main-id-register)

False negative reported by @V10lator in #206

* ARM Cortex A12 Vulnerable to 1&2

https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability

* A76 vulnerable to variant 4

All arch 8 cortex A57-A76 are vulnerable to variant 4.

https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability

* Whitelist variant4 nonvuln Arms

* ARM Cortex Whitelist & Cumulative Blacklist

Applies all information about vulnerabilities of ARM Cortex processors (from https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability).

Whitelist & blacklist approach, using both vulnerable and non vulnerable status for each identified CPU, with vulnerabilities tracked cumulatively for multi CPU systems.
