Fix #8922 (SIGSEGV below exprDependsOnThis - stack overflow?) (#1761) 
This limits the recursion depth as a last line of defense to avoid stack
overflows when there are really huge arrays.

7c7ee66cf9 Fix crash in TemplateSimplifier::TokenAndName::TokenAndName in case of template constexpr (#1748) 
This is not propper solution. This change just eliminates crash and logs error.

774464eabb Fix issue 8996: False positive duplicateCondition 
This fixes issue 8996 by improving the alias checking by using lifetime analysis. It also extends the lifetime checker to handle constructors and initializer lists for containers and arrays.

Library: Enhance minsize configuration and allow simple values. (#1736) 
Some POSIX and Windows functions require buffers of at least some
specific size. This is now possible to configure via for example this
minsize configuration: `<minsize type="value" value="26"/>`.
The range for valid buffer size values is 1 to LLONG_MAX
