* Disable pcap on android

* libretro: jni: Switch stl to c++ in prepararion for ndk r20

Also disable narrowing errors. This should be fixed properly later.

* libretro: android: fix compile

GFX3D: The polygon clipping stage now occurs before any polygon sorting, allowing for the sorting of smaller lists. This can be a significant performance improvement for some 3D scenes with high polygon counts.
- 3D renderers no longer perform polygon clipping themselves, instead relying on GFX3D to do it. By default, the clipping mode is ClipperMode_DetermineClipOnly, but 3D renderers can change this by overriding the virtual method Render3D::GetPreferredPolygonClippingMode() and returning their preferred clipping mode.

OpenGL Renderer: Revert the texture sampling hack in commit 02cd950b -- it causes graphical glitches in Sands of Destruction, especially visible within the Sky Gaol.

OpenGL Renderer: Before rendering, determine the list of clipped polygons, and then only render the clipped polygons, just like how SoftRasterizer does it. Most 3D games will see a significant performance improvement. For certain games with very high polygon count scenes, those games will see a massive performance boost.

OpenGL Renderer: Fix an occasional crashing bug that may occur when initializing the Clear Image textures. (Regression from commit 3dc860b2.)

OpenGL Renderer: Oops!!! Fix a critical bug that completely broke all rendering!!! (Regression from commit ab3d4894.)

OpenGL Renderer: In an effort to try and reduce graphical glitches whenever users try to run enhancements that were never native to the NDS to begin with, the texture sampling method is now being forced to clamp for polygons with texture coordinates of either 0.0 or 1.0.

OpenGL Renderer: Fix a bug where the incorrect buffer would be cleared when trying to clear the Fog attributes buffer while Edge Mark is disabled. Partially addresses #247. (Regression from commit 21a3fae0.)

OpenGL Renderer: Improve the overall reliability of CPU-to-GPU buffer writes, fixing a bug where certain polygons would intermittently flicker in some games. (OpenGL 3.2 only.)

OpenGL Renderer: Fix a bug where Fog rendering would fail when used with MSAA. Fixes #246. (OpenGL 3.2 only. Regression from commit 21a3fae0.)

- As a collateral improvement, this change also works as a minor optimization for the OpenGL Renderer for games that use clear images.

OpenGL Renderer: Partially revert commit 0f045d43 -- don't do the Z adjust in the vertex shader. Apparently, we shouldn't need to explicitly do this in OpenGL, as this adjustment should be automatic. Fixes a graphical glitch that can occur in "Sonic Chronicles: The Dark Brotherhood".

OpenGL Renderer: When rendering the main geometry, adjusts all Z-positions in the vertex shader so that Z is more likely to naturally fall between the depth range of 0.0 and 1.0. Further mitigates the performance cost of using the NDS-Style Depth Calculation option.

Video Filters: Fix an issue where the internal buffers were not created using a guaranteed alignment, possibly causing a segfault on AVX2-enabled systems. Fixes #245.

GPU: Fix graphical glitch that can occur when frameskip is enabled, running a custom resolution on a multicore CPU system. (Regression from commit abc0649a.)
