Update aapt source to latest (android/platform_frameworks_base@6a8f0d70b09d3e628f2b3472b1c534dd213be3ec)
https://android.googlesource.com/platform/frameworks/base.git/+log/6a8f0d70b09d3e628f2b3472b1c534dd213be3ec/tools/aapt

- switch to clang to resolve various ndk-build gcc errors introduced in NDK r14b
- suppress warnings in aapt, libandroidfw and libcutils since clang is much noisier than gcc
- clang is more rigid so work around cpp file compilation within libcutils
- a link to libatomic.a is now required
- target platform currently cannot go above android-21 due to libc.a not being up to date

- change library link order to satisfy libziparchive linkage to libbase; error: undefined reference to 'android::base::ReadFully(int, void*, unsigned int)'

- from including both platform/android-21 xattr headers in system_properties

- add system_properties from bionic to satisfy linkage to liblog; error: undefined reference to '__system_property_area_serial' (https://android.googlesource.com/platform/bionic/+/master/libc/bionic)
- add header dependencies for system_properties (https://android.googlesource.com/platform/bionic/+/master/libc/private)

- from including both platform/android-21 stdatomic and libc++ in CursorWindow

- SCREENROUND* 'is not a member of android::ResTable_config' errors with platform/android-21

- CursorWindow appears to only compile with c++ STL but several other components of libandroidfw only compile with gnu STL so split it into its own Makefile, and compile it first with c++_static STL so its object can then be used by the subsequent gnu STL compile of libandroidfw

- update .gitignore for ndk-build products

- use local built library dependencies (thanks @Surge1223)
- force static binary
- build target executable only

- SCREENROUND* 'not declared in this scope' errors with platform/android-21

- invalid conversion from 'const uint8_t* {aka const unsigned char*}' to 'Bytef* {aka unsigned char*}'
