tests: do not use basic_string_view comparison as a workaround

Radix tree: make mt mode a template parameter

mpsc_queue: do not call ringbuf_consume/release with number of byte

for C2593: 'operator ==' is ambigous on Visual Studio 14.0

if !MtMode. This improves performance for single-threaded workloads.

After this change performance difference when using MtMode true vs false
is ~ 15% for readseq in pmemkv-bench benchmarks for radix.

This allows for better optimization and getting rid of atomic
operations in single-threaded workloads.

but rather with number of cachelines. This allows to workaround
the size limitation.

radix_tree: fix pmemcheck annotation

Add helgrind/drd suppress files for valgrind 3.17

mpsc_queue: allow interrupting try_consume_batch

Use annotation only if PMEMCHECK is enabled (not just any valgrind tool).

If interrupt (exception) happens, next try_consume_batch will
resume from the previous position.

inline_string: do not check if inline_string is on pmem

Radix: concurrent erase

In pmemkv we have a use for keeping inline_string in DRAM. It's
also safe (unlike for e.g. pmem::obj::string) since inline_string
does not manage allocations.

radix_tree: fix key comparison in internal_bound

Ubsan fixes

Weekly fixes

p_ext_0_none fails with:
"runtime error: shift exponent 127 is too large for 32-bit type 'int'"

concurrent_hash_map_layout_0_none fails with:
"runtime error: reference binding to null pointer of type ..."

Cast to unsigned was in wrong place. We casted result of assignemnt
which already overflowed which resulted in the follwowing error in
multiple radix tests under UBSAN:

"runtime error: signed integer overflow: 5 + 2147483647 cannot be
represented in type 'int'"

Previously it was default-initialized to nullptr in copy ctor
from non-const iterator which resulted in the following error
for multiple radix tests under UBSAN:

"runtime error: member call on null pointer of type ..."

Original implementation resulted in the following error in multiple
radix tests under UBSAN:

"runtime error: reference binding to misaligned address 0x7fc4f7bc08dc
for type 'const double', which requires 8 byte alignment"

Key's bytes should be compared as unsigned chars. Otherwsie
thse comparison will yield incorrect result for values < 0.

Radix tree concurrent fix

Found by weekly USAN tests

* add missing pmreorder suffix
* remove unnecessary mpsc_queue prefix

Simplify previously imported EBR to C++. Modify radix_tree to work with it.

Add tests to check if garbage collection is done properly when we are
erasing and reading concurrently from the radix.

they are not compatible

mpsc_queue: improvements needed by multi-tier engine

in radix_tree_iterator::operator++/-- <-> internal_bound. The recursion
caused stack overflow errors, e.g. : https://github.com/pmem/libpmemobj-cpp/issues/1091

Fix Clang detection

CI: add new workflow with more jobs

- use CMAKE_CXX_COMPILER_VERSION/CMAKE_C[XX]_COMPILER_ID for
  setting compiler conditions
- fixes #1090

by renaming 'other_OSes.yml' to 'nigthly.yml' and reordering some jobs.

executing USAN, UBSAN and valgrind tests using upstream valgrind's package.
