ec87dd4d49 Abort LSTM training with integer model (fixes issue #1573) 
Tesseract currently cannot continue LSTM training from an
integer (fast) model.

Report this to users who try it nevertheless instead of crashing
with an assertion.

a027dca007 Extend URI support for Tesseract with libcurl 
libcurl not only supports HTTP and HTTPS, but also a lot of other protocols,
for example FTP and SFTP. Those protocols can also be useful for Tesseract.

40fdacd485 Add missing check for __ARM_NEON 
This makes it consistent with intsimdmatrixneon.cpp file and allows having this file included in builds even for non-NEON platforms (simplifies build config).

bb4a1219d7 Improve setting of dot product functions via environment variable 
Apply the settings which are selected by environment variable DOTPRODUCT
after the autodetection which detects the available SIMD hardware.

'accelerate', 'fma' and 'std::inner_product' now no longer change
the setting for intSimdMatrix to 'generic' because they don't provide
their own implementation for it.
