first part of bugfix [#24376] Fly mode disturbs the rotation or scale of the camera object
object_apply_mat4 was incorrectly negating the matrix values,

This worked in most cases but even when it worked would end up with negative scales too often.
now when no negative scale is used they will all stay positive and from my tests it works in all cases now.

Closing #24367 (Incorrect behaviour for Optimal Display option) and reopening #22634 (sculpting/multires and wireframe display mode glitches)

* Reverting my earlier changes to subsurf edge drawing; seems to be causing more bugs than the minor bug it fixed.

move fly mode operator into its own file.

* Another attempt to fix the bug partly addressed in revision 31419.

* Fix for the missing function declaration of strcpy. This caused
a linker error in the Debug build with x64 VC 2008 and CMake.

== addons ==

- new (and temporary) directory addons_extern/ to store external projects addons

Merged changes in the trunk up to revision 32684.

Remove the unsigned, since totbits is signed too.

Make sure separation between modifier keys is communicated from GHOST upwards too (BGE at least uses this).

rna rename: use_inherit_rotate -> use_inherit_rotation, noticed _rotate is not used like this much elsewhere in rna.

Collada : header files order dependency was making osx compile fail

bugfix [#24357] Font folder can be specified but is not opened
- open operator was incorrectly checking if the font path was set.
- rna ID editable check was also incorrect, checking the ID name rather then the filename.
- use define FO_BUILTIN_NAME rather then "<builtin>".

bugfix [#21097] Rotating multiple bones with non-local location behaves incorrectly.
- rotation and bone scaling with Durian feature 'Local Location' would fail to correctly translate the bone
because a different matrix is needed for translation and rotation.

Added CMake macro REMOVE_STRICT_FLAGS(), this means developers can build with -Werror in their CMAKE_C_FLAGS_DEBUG (so all warnings give errors).
but external libs which we don't maintain & generated code will have -Werror removed.

This is GCC only, MSVC can be added easily.

Fixed bug #24364, "subsurf modifier causes wire-only meshes to disappear in object mode."

* Re-added code to draw loose edge

Fully disable AUD's FFTW3 usage.

Added support for dashed line in the Parameter Editor mode.

warning fixes.

CMake options to disable Decimate and Boolean Modifiers: WITH_MOD_BOOLEAN, WITH_MOD_DECIMATE, renamed WITH_FLUID to WITH_MOD_FLUID

Remove msvc build files which are not needed anymore.

fix for implicit declaration
