Currently we run all tests via Valgrind. This patch adds 2nd batch of
tests which are compiled with Clang AddressSanitizer[1],
LeakSanitizer[2] and UndefinedBehaviorSanitizer[3] in order to catch
more issues during QA on CI.
AddressSanitizer is a fast memory error detector. The tool can detect
the following types of bugs:
* Out-of-bounds accesses to heap, stack and globals
* Use-after-free, use-after-return, use-after-scope
* Double-free, invalid free
LeakSanitizer is a run-time memory leak detector. It can be combined
with AddressSanitizer to get both memory error and leak detection, or
used in a stand-alone mode.
UndefinedBehaviorSanitizer (UBSan) is a fast undefined behavior
detector. UBSan modifies the program at compile-time to catch various
kinds of undefined behavior during program execution, for example:
* Using misaligned or null pointer
* Signed integer overflow
* Conversion to, from, or between floating-point types which would
overflow the destination

clang-10 analyzer reports following:
base64.c:325:20: warning: Array access (from variable 'target') results in a null pointer dereference
target[tarindex] = 0;

and prepared test case confirms it:

For improved QA etc. For the start with initial test cases for avl,
base64, jshn and list components. Moved runqueue and blobmsg from
examples to tests. Converted just a few first test cases from
json-script example into the new cram based unit test, more to come.
