cve-check: backport rewrite from master

As detailed at [1] the XML feeds provided by NIST are being discontinued on
October 9th 2019.  As cve-check-tool uses these feeds, cve-check.bbclass will be
inoperable after this date.

To ensure that cve-check continues working, backport the following commits from
master to move away from the unmaintained cve-check-tool to our own Python code
that fetches the JSON:

546d14135c5 cve-update-db: New recipe to update CVE database
bc144b028f6 cve-check: Remove dependency to cve-check-tool-native
7f62a20b32a cve-check: Manage CVE_PRODUCT with more than one name

c0eabd30d7b cve-update-db: Use std library instead of urllib3

-Subject: [PATCH] curl: allow overriding default CA certificate file
-
-Similar to curl, --cacert can now be used in cve-check-tool and
-cve-check-update to override the default CA certificate file. Useful
-in cases where the system default is unsuitable (for example,
-out-dated) or broken (as in OE's current native libcurl, which embeds
-a path string from one build host and then uses it on another although
-the right path may have become something different).
-
-Upstream-Status: Submitted [https://github.com/ikeydoherty/cve-check-tool/pull/45]
-
-Signed-off-by: Patrick Ohly <patrick.ohly@intel.com>
-
-
-Took Patrick Ohlys original patch from meta-security-isafw, rebased
-on top of other patches.

-Subject: [PATCH] update: Compare computed vs expected sha256 digit string
- ignoring case
-
-We produce sha256 digest string using %x snprintf()
-qualifier for each byte of digest which uses alphabetic
-characters from "a" to "f" in lower case to represent
-integer values from 10 to 15.
-
-Previously all of the NVD META files supply sha256
-digest string for corresponding XML file in lower case.
-
-However due to some reason this changed recently to
-provide digest digits in upper case causing fetched
-data consistency checks to fail. This prevents database
-from being updated periodically.
-
-While commit c4f6e94 (update: Do not treat sha256 failure
-as fatal if requested) adds useful option to skip
-digest validation at all and thus provides workaround for
-this situation, it might be unacceptable for some
-deployments where we need to ensure that downloaded
-data is consistent before start parsing it and update
-SQLite database.
-
-Use strcasecmp() to compare two digest strings case
-insensitively and addressing this case.
