Remove redundant variable and manipulation thereof
Reverted refactoring 828417c for now. It caused a major slowdown in the unused functions checking.

Fix SEGV on Solaris x86

On Solaris x86, with both GCC 4.8 and 4.9, running cppcheck causes a segmentation fault when process terminates.

The destructor order is somehow getting messed up on this platform.

This fix moves the code away from header file and ensures _instances remains valid during termination.

Fixed #6268 (False positive functionStatic (inconclusive) - nested namespaces)
Add VS2013 projects for my personal use (using /LTCG, /MP, /RELEASE, /MT).

[ci skip]
Add a script to run coverity with VS2013.

[ci skip]
Move astyle options to astyle.ini.

This way we can use it in runastyle and runastyle.bat.

Settings changes:
* specify the files to exclude instead of specifying the files to style
* remove `--lineend` option
* keep the file's modified timestamp
* only show the styled files on the command output

Also change the astyle version check to only check for older not the exact version.

[ci skip]
Update runastyle.bat from MPC-HC.

It includes a check if astyle is present and for astyle's version.
Also, it allows drag and dropping files onto it to style them.

[ci skip]
PEP8 fixes.
