On most systems double is the IEEE 754 double-precision binary
floating-point format (64 bits). Tesseract does not support other systems.

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.

Remove unneeded include statements, remove conditional statements and
replace the remaining assert.h by their standard C++ variant cassert.

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.

Coverity Scan does not like incrementing of a null pointer,
so increment an index value instead of a pointer.

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.

The assertions introduced by commit 8bea6bcc12
were too strict. The first one failed in osd_test, the second one failed
in `tesseract IMAGE BASE --psm 13 lstm.train`.

Raise an assertion for unexpected arguments and use size_t instead of int
for the size argument which is typically sizeof(some_datatype).

The progress reporting function returns a boolean. The returned
value is never used by the tesseract and its meaing is not
documented, which renders the value meaningless. Still, lack of
return should not be premitted.
The progress_callback field in the ETEXT_DESC monitor type does not
take any 'context' parameter, which may make implementing callback
functions difficult and may require use of global variables.
The new function receives the ETEXT_DESC pointer as an argument.
This makes it possible to share the cancel_this field as context
carrier if required.
The change is backwards-compatible: the old pointer remains as a
member of the class, and the default value for the new pointer is
a function calling the classic progress notifier. This way the code
unaware of the new member will continue to work as before.
It's still possible to set the warning level in the project settings,
but single source files should normally not disable compiler warnings.
