17e2bf5717 core(tls): implement releasing of TLS on thread termination 
- move TLS & instrumentation code out of core/utility.hpp
- (*) TLSData lost .gather() method (to dispose thread data on thread termination)
- use TLSDataAccumulator for reliable collecting of thread data
- prefer using of .detachData() + .cleanupDetachedData() instead of .gather() method

(*) API is broken: replace TLSData => TLSDataAccumulator if gather required
(objects disposal on threads termination is not available in accumulator mode)

9ca9249992 Merge pull request #15527 from everton1984:faster_acc 
* Adding support for vectorized masking for uchar/ushort.

* Fixing bug where mask was zeroing the dst. Improved the way to calculate
the mask and tweaked for further performance improvements.

* Fixing mask comparison test.

* Restricting to one channel.

* Adding support for 3 channels, switch old approach to start using HAL's
v_select.

Crosscorr cleanup (#14936)

* Simplify code for convolution destination type/size

For the 2d filter code, destination size equals source size, and the
crossCorr function even (re-)creates the output matrix with the given size.

The number of channels also have to match. The destination type() is the
one used to create the output matrix, so we can use its type() here.

This is a preparatory patch.

Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de>

* Remove redundant destination size and type parameters from crossCorr

All calling sites of crossCorr already use (...,
mat, mat.size(), mat.type(), ...), so the parameters are redundant.
