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.

e8d5838424 windows.cfg: Remove buffer-size for HeapAlloc(); travis problems. 
There is an internal error somewhere in the tests for the Heap*
functions. Removing the attribute maybe makes travis happy again for
now. The problem should get fixed though.

0d14bdac22 windows.cfg: Add "buffer-size" attributes, fix allocation configuration. 
Memory allocated with `_aligned_*malloc*()` must be freed with
`_aligned_free*()`. Using `free()` is illegal.
See
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/aligned-malloc
for details.
Also add tests for some of the changed functions.

.travis.yml: Add retries to the apt-get commands. (#1749) 
Travis often fails to update / install the packages via `apt-get` and
jobs must be restarted manually. This should fix the problem or at least
reduce the frequency at which these failures occur.
Details about the problem and the `travis_retry` command can be found
here:

Libraries: Move valloc() from std.cfg to posix.cfg. (#1743) 
Move valloc() to posix.cfg since it is a legacy POSIX function and not
part of the standard (not even commonly used). It is not available in
msvc (Visual Studio).

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
