OE-11 Logging revamp (#13909)

* Initial commit for log tag support.

Part of #11003, incomplete. Should pass build.

Moved LogLevel enum to logger.defines.hpp

LogTag struct used to convey both name and log level threshold as
one argument to the new logging macro. See logtag.hpp file, and
CV_LOG_WITH_TAG macro.

Global log level is now associated with a global log tag, when a
logging statement doesn't specify any log tag. See getLogLevel and
getGlobalLogTag functions.

A macro CV_LOGTAG_FALLBACK is allowed to be re-defined by other modules
or compilation units, internally, so that logging statements inside
that unit that specify NULL as tag will fall back to the re-defined tag.

Line-of-code information (file name, line number, function name),
together with tag name, are passed into the new log message sink.
See writeLogMessageEx function.

Fixed old incorrect CV_LOG_VERBOSE usage in ocl4dnn_conv_spatial.cpp.

* Implemented tag-based log filtering

Added LogTagManager. This is an initial version, using standard C++
approach as much as possible, to allow easier code review. Will
optimize later.

A workaround for all static dynamic initialization issues is
implemented. Refer to code comments.

* Added LogTagConfigParser.

Note: new code does not fully handle old log config parsing behavior.

* Fix log tag config vs registering ordering issue.

* Started testing LogTagConfigParser, incomplete.

The intention of this commit is to illustrate the capabilities of
the current design of LogTagConfigParser.

The test contained in this commit is not complete. Also, design changes
may require throwing away this commit and rewriting test code from
scratch.

Does not test whitespace segmentation (multiple tags on the config);
will do in next commit.

* Added CV_LOGTAG_EXPAND_NAME macro

This macro allows to be re-defined locally in other compilation units
to apply a prefix to whatever argument is passed as the "tag" argument
into CV_LOG_WITH_TAG. The default definition in logger.hpp does not
modify the argument. It is recommended to include the address-of
operator (ampersand) when re-defined locally.

* Added a few tests for LogTagManager, some fail.

See test_logtagmanager.cpp
Failed tests are: non-global ("something"), setting level by name-part
(first part or any part) has no effect at all.

* LogTagManagerTests substring non-confusion tests

* Fix major bugs in LogTagManager

The code change is intended to approximate the spec documented in
https://gist.github.com/kinchungwong/ec25bc1eba99142e0be4509b0f67d0c6

Refer to test suite in test_logtagmanager.cpp

Filter test result in "opencv_test_core" ...
with gtest_filter "LogTagManager*"

* Added LogTagManagerNamePartNonConfusionTest.

See test_logtagmanager.cpp in modules/core/test.

* Added LogTagAuto for auto registration in ctor

* Rewritten LogTagManager to resolve issues.

* Resolves code review issues around 2019-04-10

LogTagConfigParser::parseLogLevel - as part of resolving code review
issues, this function is rewritten to simplify control flow and to
improve conformance with legacy usage (for string values "OFF",
"DISABLED", and "WARNINGS").

core: eliminate coverity scan issues (#14162)

* core(hal): avoid using of r,g,b,a parameters in interleave/deinterleave

- static analysis tools blame on possible parameters reordering
- align AVX parameters with corresponding SSE/NEO/VSX/cpp code

* core: avoid "i,j" parameters in Matx methods

- static analysis tools blame on possible parameters reordering

* core: resolve coverity scan issues

This reverts commit 3721c8bb
except changes in modules/dnn/test/test_tf_importer.cpp

* Add Operator override for multi-channel Mat with literal constant.

* simple test

* Operator overloading channel constraint for primitive types

* fix some test for #13586

Fix a bug in cv :: merge when array of 3-channel mat is input (#13544)

* Mat merge function bug fix - Bug fix of merge function of 3-channel vector <Mat> of 3 or 4 matrices

* Add Core_merge test for opencv#13544

* fixups

to verify SIMD code path

* Support for Matx read/write by FileStorage

* Only empty filestorage read now produces default Matx. Split Matx IO test into smaller units. Test checks for exception thrown if reading a Mat into a Matx of different size.

* integrated the new C++ persistence; removed old persistence; most of OpenCV compiles fine! the tests have not been run yet

* fixed multiple bugs in the new C++ persistence

* fixed raw size of the parsed empty sequences

* [temporarily] excluded obsolete applications traincascade and createsamples from build

* fixed several compiler warnings and multiple test failures

* undo changes in cocoa window rendering (that was fixed in another PR)

* fixed more compile warnings and the remaining test failures (hopefully)

* trying to fix the last little warning

  - initialize arithmetic dispatcher
  - add new universal intrinsic v_absdiffs
  - add new universal intrinsic v_pack_b
  - add accumulate version of universal intrinsic v_round
  - fix sse/avx2:uint8 multiplication overflow
  - reimplement arithmetic, logic and comparison operations into wide universal intrinsics
    with full support for all types
  - reimplement IPP arithmetic, logic and comparison operations in a sperate file arithm_ipp.hpp
  - avoid scalar multiplication if scaling factor eq 1 and use integer multiplication
  - move C arithmetic operations to precomp.hpp and delete [arithm_simd|arithm_core].hpp
  - add compatibility with new opencv4 divide policy

* Updated ICV packages and IPP integration

Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.

  - redefine 16-bit multiply operator to perform saturating multiply
    instead of non-saturating multiply
  - implement 8-bit multiply operator to perform saturating multiply
  - implement v_mul_wrap() for 8-bit, 16-bit non-saturating multiply
  - improve performance of v_mul_hi() for VSX
  - update intrin tests with new changes
  - replace unv 16-bit multiplication operator with v_mul_wrap due behavior changes
