The mentioned security setting is relevant for accessing
external media like RAW block devices (/dev/xxx), which is one of
the main use cases for this module (modern Macs do not have internal
optical drives anymore).

Probe for this case explicitly to inform the user how to get
access.

This is only relevant starting with macOS Catalina.

2.9.1 had bogus PS due to untested CVE fixes

The current git master version of mingw-w64 activates
__USE_MINGW_ANSI_STDIO by default if targeting C99 (which is the
default C version in both GCC and Clang), unless using UCRT.

This patch (a backport of ca6f6cfbb4c78c063f2a50bb758edfc95c9d64a2
from gettext git) fixes building gettext when __USE_MINGW_ANSI_STDIO
is enabled - i.e. fixing building gettext with latest mingw-w64 when
using msvcrt.dll.

Rather than creating and immediately deleting the variable.

When the native SurfaceTexture API is available, construct a SurfaceTexture
object from Java through JNI calls and store the producer side
(Surface/ANativeWindow) for the AWindowHandler clients.

The SurfaceTexture constructor is only available since API 26 but the NDK
API for ASurfaceTexture already require API 28

To use new native functions, we wrap ASurfaceTextureAPI structure pointers
inside a new set of native functions, it allow to describe some specifics
behaviors for the NDK API.

If the NDK API requierements are met, native functions for ASurfaceTexture are
used instead of their JNI counterpart. The behavior change is made through the
SurfaceTextureHandler pointer structure.

Then, in all cases, wrap pointers of SurfaceTextureHandler in a common functions
used by OpenGL to attach / update / detach textures.

The methods from the SurfaceTexture and AndroidNativeWindow structures are
methods of the AWindow class.
Both structures are now merged inside struct AWindow.

SurfaceTexture structure will be used for SurfaceTexture methods and class.

uninitialized values if vm state is borked

This was happening when the instant ratio was smaller than the fixed ratio
(when the user ask for a playback speed > 1).

Fixes issue 956 on vlc-android.

The core is already taking care of smooth rate change (when the resampler is
used to catch up a delay).

Drawing an NSGradient into an empty bezier path causes an exception,
crashing the application.

Because calling libvlc_media_player_get_full_title_descriptions(), getting the
title via the index and releasing the whole list is not convenient to get the
info about the selected title.

In 3.0, this event was sent for a new selection and for a new list.

ffmpeg doesn't build without gas-preprocessor on armv7 for iOS.

This is a workaround to have the CI running on this platform but it
should eventually go as gas-preprocessor shouldn't be needed anymore.

As vpx buildsystem adds -fembed-bitcode as long as iphone target is > 8
it makes the build fails on compilers not supporting bitcode embedding.

In any case, we enable bitcode embedding ourselves by adding it to the
contribs CFLAGS, which ends up in --extra-cflags in vpx.

It fixes build for iOS armv7 as libtool expects a --tag on ios armv7
builds for assembly files. I don't really know why it need this
addition to accept compiling though...

de-versionning was done before alias selection, and armv7-apple-darwin
wasn't aliased to arm-apple-darwin, leading to failure finding the
correct triplet.

CoreServices is an iOS 12.0+ API so it cannot be linked when targetting
iOS 9.0. However it is still needed for MacOS and available since 10.0+
which is lesser than the target version.

See https://developer.apple.com/documentation/coreservices

This is particularily needed when ar and $(HOST)-ar are not producing
the same type of archive, like linux -> iOS cross compilation.

The pain point was that $(HOST)-ar doesn't exist on MacOSX as there is
no triplet-prefixed tools. This has become useless as we now enforce the
correct variant through `xcrun --find` in apple buildscripts.

ffmpeg rules.make is passing the variable to configure, and nm can be
present in different flavour, for example in linux/macosx
cross-compilation environments.

Vanilla clang doesn't seem to take the -Wl,--ios-version-min flag into
account and adding this flag doesn't break apple clang build.

It allows finding the correct ar when cross-compiling from Linux and
allows simplifying the contrib Makefile.
