9a74c4ccad viewer: Use std::unique_ptr in waiting_for_events data structure 
The current usage of waiting_for_events is taking ownership of SVEvent
pointer from a unique_ptr. This is error prone as all code paths using
waiting_for_events need to ensure deletion. We fix it by using
unique_ptr in waiting_for_events and all dependent code paths.

Povilas Kanapickas
4f831ff489 viewer: Fix double free caused by ScrollView::MessageReceiver 
waiting_for_events takes ownership of the passed event which is later
deleted. Since we use unique_ptr::get() to acquire the pointer, we cause
double free: one free happens in the code path where the event from
waiting_for_events goes and the other free happens in unique_ptr
destructor.

The fix is to move ownership out of unique_ptr by unique_ptr::release().

ebf367e248 Partially revert changes of list data types (fix compiler warnings) 
Changing from class to struct causes clang compiler warnings like this one:

In file included from ../../../src/api/baseapi.cpp:63:
../../../include/tesseract/osdetect.h:29:1: warning: class 'BLOB_CHOICE_LIST' was previously declared as a struct; this is valid, but may result in linker errors under the Microsoft C++ ABI [-Wmismatched-tags]
class BLOB_CHOICE_LIST;

ELISTIZEH(BLOB_CHOICE)

BLOB_CHOICE_LIST
^
../../../include/tesseract/osdetect.h:29:1: note: did you mean struct here?
class BLOB_CHOICE_LIST;
^~~~~

As it is not possible to change the API header tesseract/osdetect.h,
some of the changes from class to struct had to be reverted.
