DocumentsProvider: detect symlink to dirs
tree: remove ceph.patch
this is unused since pacific rebase, which source is hosted in a new
standalone repo
DocumentsProvider: unify metadata row building
this also fix a case where full path are taken as display names
DocumentsProvider: simplify logging and toasting
DocumentsProvider: wrap remaining mount() to throw IOE
CephFSDocumentsProvider: simplify mount setup handling
CephFSDocumentsProvider: improve log messages
CephFSDocumentsProvider: root: improve naming
make title shorter, and move cephfs string to summary, which makes it
friendlier to stock DocumentsUI with phone screen
jni: update prebuilts from ceph v16.2.7 rebase, un-lfs
newer ndk r23.b toolchain seems to produce a lot smaller binaries, and
we can now get rid of lfs. old binraries are branched at
old-prebuilts-lfs branch on github.
build: require sdk runtime minimum 24
this restriction actually already exists for a long time, from libceph*
libraries. ceph needs:
ns_* from arpa/nameser.h, __INTRODUCED_IN_64(22)
{get,free}ifaddrs from ifaddrs.h, __INTRODUCED_IN(24)
CephFSDocumentsProvider: lookup mime-type on symlinks
build: use maven central instead of jcenter
make mount timeout configurable
DocumentsProvider: toast and unset global handle on mount errors
update prebuilt ceph libs to pacific
DocumentsProvider: setup ceph only when needed
DocumentsProvider: set ceph mount timeout to 20
DocumentsUI on Pixels seems to have a timeout of 20.
Default timeout of 300 is too long, let's make it 20 for now.
To be configurable in future.
