README: reflect boost build change
jniLibs: remove links
seems not needed with bundled boost
ceph: rebase onto 19.2.0, build boost
Containerfile: remove aarch64 boost, add native clang
in preparation of building boost via ceph build
ceph: rebase onto 18.2.4
with performance patch upstreamed
ceph: update for cmake compatibility backport
build.gradle: update cmake version to match image
Containerfile: clean pacman pkg cache
CephFSDocumentsProvider: reduce io need for thumbnails on dir listing
CephFSDocumentsProvider: basic xdg-style thumbnail support
needs more work on reducing io @ dir listing, and perhaps validations
move to android-ndk-beta
for better c++20 stdlib support, and prepare for moving to reef
link libcephfs-jni java parts instead of copying
README: document new build approach
jni: add libc++_shared.so link as blob into jniLibs
somehow gradle did not pick this up, needed by libboost
TODO: find out how agp deals with lib deps
add our ceph fork as a submodule
to be wired up with gradle later
Containerfile: riggings for ghcr
