5deb0b024e build, test, doc: Temporarily remove Android-related stuff (Hennadii Stepanov)
Pull request description:
Previously, our Android builds were geared towards generating APKs, which relied on Qt. However, after migrating to C++20, compiling for Android became unfeasible due to Qt 5.15's compatibility limitations with NDK only up to r25, which includes an outdated embedded libc++ (see https://github.com/bitcoin/bitcoin/issues/29360).
All removed stuff will be reinstated after migrating the build system to CMake and upgrading Qt to version 6.x.
This PR makes possible a clean migration to the CMake-based build system as it removes code, which is not used at this moment.

Variables that are declared with AC_ARG_VAR macro are substituted via
AC_SUBST macro.
PKG_CHECK_MODULES macro already has AC_ARG_VAR(${PACKAGE}_CFLAGS) and
AC_ARG_VAR(${PACKAGE}_LIBS).
Very old shells suffered from bugs which meant that prefixing variables
with an "x" to ensure that the lefthand side of a comparison always
started with an alphanumeric character was needed. Modern shells don't
suffer from this issue (i.e Bash was fixed in 1996).
In any case, we've already got unprefixed checks used in our codebase,
i.e https://github.com/bitcoin/bitcoin/blob/master/configure.ac#L292,
and have dependencies (in depends) that also use unprefixed comparisons.
I think it's time that we can consolidate on not using the x-prefix
workaround. At best it's mostly just confusing.

remove fix_configure_mac.patch
Fixed upstream: https://bugreports.qt.io/browse/QTBUG-67286
remove fix_riscv64_arch.patch
Was fixed upstream in 6a39e49a6cdeb28a04a3657bb6a22f848d5dfa9d
remove fix_rcc_determinism.patch
Fixed upstream in https://bugreports.qt.io/browse/QTBUG-62511
remove freetype_back_compat.patch
By the time we ship a release with Qt 5.12, we'll certainly no-longer be
supporting Ubuntu 14.04 and Ubuntu 16.04 ships with FreeType 2.6.1,
which is new enough that using the symbol is no-longer an issue.
The renaming of FT_Get_X11_Font_Format() happened in FreeType 2.6
remove xkb-default.patch
This was removed upstream in d5abf545971da717014d316127045fc19edbcd65

cf0681133a build: disable D-Bus on Android by default (Igor Cota)
Pull request description:
I've been trying to build for Android on different OSes/Gitian with varying success. Build system is quite the beast and sometimes it doesn't get it right. To make sure it does these three little tweaks make the Android build more robust:
- disable D-Bus (Android doesn't support it and has its own way to trigger notifications)
- don't flag `-lpthread` when linking Boost, [Bionic has built-in support](https://stackoverflow.com/questions/30801752/android-ndk-and-pthread)
- ~~add `-static-libstdc++` to linker flags. This avoids having to bundle `libc++_shared` with CLI apps, still necessary with `bitcoin-qt` though (thanks Sjors)~~
I think these are small and fairly straightforward so I put them all into this one PR.

This change adds to the BITCOIN_QT_CONFIGURE script ability to use
pkg-config for MinGW. All of the non-pkg-config paths are removed as
needless.
If depends is built with DEBUG=1 the configure script fails to pickup
