Radix tree assing val fix

Fix value() function which was creating an empty string (wrong input parameter)
and add testcases for basic_inline_string<uint8_t> and basic_inline_string<wchar_t>
as value types.

Realocating path should be taken for values which are instances
of basic_inline_string<CharT, Traits> (not only for CharT = char).

coloring in IDE was not applied, because of this additional new line

add stable-1.11 to valid branches

tests: string_view_assignment

cmake: look for libpmemobj also when building benchmarks

radix_tree: fix upper_bound implementation

- string_view_assignment.pass test port
- T_size_size.pass test port

In internal_bound we actually rely on leaf node to be the leftmost one.

If a key was not present in a radix tree and a slot variable was
set to &root, next_leaf function lead to accessing uninitialzied memory
(we tried to increment slot, as if it was a pointer to an element in array).

fix ChangeLog 1.11-rc2

- changed to be consistent with the C++ specs

string_view: enable string_view.fail test

- enable string_view.fail test

- add explicit to basic_string(const T &t) constructor

docker: cron workflows are no longer for coverity jobs only

add CMake flag for pmreorder tests

tests: fix syncthreads implementation

Radix tree improvements

Since std::condition_variable::wait can wakeup spuriosly we need to
pass a predicate to wait.

and turn it on by default in CI. Check if pmreorder >= 1.9
- it guarantees reliable output.

unifdef generic tests (txabort, assignment op) and
extend insert_or_assign, try_emplace tests.
