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.

Most parameters can also get the const attribute.

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.

One of the checks was too restrictive, as lstmeval deserializes
char arrays with 14000000 elements, so raise the limit to 30000000.
That check was added in commit 992031e824.
Add also assertions which help finding such problems in debug mode.

Commit 4d514d5a60 introduced tprintf_internal
with an additional argument "level" which was removed again in commit
7dc5296fe9.
So we can now restore the original state without tprintf_internal.
Remove also the declaration of debug_window_on (it does not exist since
commit 030aae9896) and make the
configuration parameter debug_file local as it is only used by tprintf.

Wrong file data could give a large value for the number of vector elements
resulting in very large memory allocations.
Limit the allowed data range to UINT16_MAX (65535) elements
which hopefully should be sufficient for all use cases.
Changing the data type of the related member variables from int to
uint32_t allowed removing several type casts.
