* 'master' of https://github.com/tesseract-ocr/tesseract:
Remove code for _MSC_VER < 1900
keep API compatibility with #1265
Update googletest submodule to release v1.8.1
Update test submodule
Always use isascii() with isspace()
Avoid crash with --psm 0 and LSTM traineddata
SVPaint: Remove empty block
Classify: Don't hide debug parameter
UNICHARMAP: Remove comparison which is always false
svpaint: Change a variable from global to local
pgedit: remove unused declaration of display_bln_lines
Plumbing: Remove comparison which is always false
Release candidate 2
use pdf L_FLATE_ENCODE only for png input; fixes#1961
isspace() must only used with an unsigned char or EOF argument,
and even then its result can depend on the current locale settings.
While this is not a problem for C/C++ executables which use the default
"C" locale, it becomes a problem when the Tesseract API is called from
languages like Python or Java which don't use the "C" locale.
By calling isasci() before calling isspace() this uncertainty can be
avoided, because any locale will hopefully give identical results for
the basic ASCII character set.

Poor global variable name 'rgb'. Prefer longer, descriptive
names for globals (eg. kMyGlobalConstant, not foo).

This fixes warnings from LGTM:
Comparison is always false because id >= 0.
Comparison is always true because mirrored >= 1.
Comparison is always false because id >= 0.
INVALID_UNICHAR_ID is -1, so the warnings are correct.

Most parameters can also get the const attribute.

This fixes warnings from LGTM:
Multiplication result may overflow 'float' before it is converted
to 'double'.
While the sqrt function always calculates with double, here the
overloaded std::sqrt can be used to handle the float arguments
more efficiently.
Replace also an old C++ type cast by a static_cast.

Warning from LGTM:
Resource data_ is acquired by class GenericVector<FontSpacingInfo *>
but not released in the destructor.
LGTM complains about data_ not being deleted in the destructor.
The destructor calls the clear() method, but the delete there
was conditional which confuses the static code analyzer.

wildcard_unichar_id_, apostrophe_unichar_id_, question_unichar_id_ and
slash_unichar_id_ were not initialized in the constructor.
slash_unichar_id_ was used later in a conditional.
