Revert "Merge pull request #3330 from Sintun/master" (#3505) 
This reverts commit 122daf1d64, reversing
changes made to 4cd56dc5f5.

Those changes caused two regressions which resulted in an assertion
or a segmentation fault.

444fe14273 Fix a couple of 'shadowed local variables' compiler warnings 
These fixes got through while I manually extracted the template work
from my mainline (warnings due to running MSVC at Level 4)

f72d4b1fe7 NEON arch: dead ref cycle fix 
When neon_available_ is ON, the DotProduct was set to point to DotProduct,
which should have been DotProductNative, as dotProduct is the *target* global itself:
see simddetect.h --> effectively making that part of the SetDotProduct() call
identical to this (no-op) statement: `DotProduct = DotProduct;`

Also added the Neon check in the Update() API, where it exists together
with the other checks (for AVX/SSE/etc.)

[sw: formatted commit message and merged into main branch]

Add --reset_learning_rate option to lstmtraining (#3470) 
When the --reset_learning_rate option is specified,
it resets the learning rate stored in each layer of the network
loaded with --continue_from to the value specified by the --learning_rate option.
If checkpoint is available, it does nothing.

c24538518c ThresholdMethod::TiledSauvola -> ThresholdMethod::Sauvola 
The fact that this method uses tiles is implementation detail. It does not change the result compared to Sauvola without tiles. The use of tiles minimize memory consumption.
