66b77e6639 Prepare using float instead of double for LSTM calculations 
The new header file ccutils/tesstypes.h also prepares support
for larger images by introducing a new data type for image
size and coordinates (still unused).

FloatToDouble is now a local function.

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.

bf3421ff12 Fix autoconf build for latest MacOS (Intel and M1) 
On latest MacOS 11.3 the system header file "ostream" includes a file
named "version".

The macro DEFAULT_INCLUDES adds the source root to the list of include
directories by default. As MacOS uses a case insensitive file system,
the compiler finds and includes the file "VERSION" there which causes
compiler errors and a failing build process.

Setting an empty DEFAULT_INCLUDES fixes that, but requires moving
config_auto.h to another directory in the include search path.

f79e52a7cc NEON SIMD code. 
In tests on my pi3b+, a release build of my ghostscript integration
takes 2 minutes 27 seconds to render a PDF and OCR it with the
vanilla sources. With this NEON coded added the time drops to 37
seconds.

I have not tested the configure/Makefile changes as I'm not using
them.
