The changes are based on an analysis done with include-what-you-use.

Replace also some standard header files by the corresponding
standard C++ header files.

44450094c3 Replace ASSERT_HOST in genericvector.h 
genericvector.h used a mix of assert and ASSERT_HOST.

By using assert only, it does no longer depend on errcode.h
which defines the ASSERT_HOST macro.

Other files which still use ASSERT_HOST now need an explicit
include statement for errcode.h.

c1c87d73ee Require tesseract/ for API header files (fixes potential name conflicts) 
The tesseract/ subdirectory is no longer automatically added to the
include path of the compiler. Therefore old code which used code like

    #include "capi.h"

must now change that to

    #include "tesseract/capi.h"

This avoids name conflicts with header files from other projects.

Test for correct locale settings

Stefan Weil
3292484f67 Test for correct locale settings 
Normal C++ programs like those which are built for tesseract automatically
set the locale "C".

There can be different locale settings if the tesseract library is used
in other software.

A wrong locale can cause wrong results from sscanf which is used at
different places in the tesseract code, so make sure that we have the
right locale settings and fail if that is not the case.
