Merge csync_create and csync_init into the constructor and
replace csync_destroy with the destructor.
Also use a QByteArray for csync_s::root_perms and flatten
csync_rename_s as a rename sub-struct of csync_s since it
can now handle C++ types.
Also move csync_normalize_etag to common/utility since we
don't need the char* function anymore.
Remove the single space file_stat->remotePerm codepath since
this won't be used in csync anymore since
8de3bda0b1.
Issue #1817
This is the first commit trying to unify csync_file_stat_s,
csync_vio_file_stat_s and csync_tree_walk_file_s. Use QByteArray
and unique_ptr already since I'm not used to track memory allocations
and this will make the transition easier.
Issue #1817
Now that csync builds as C++, this will avoid having to implement
functionalities needed by csync mandatorily in csync itself.
This library is built as part of libocsync and symbols exported
through it.
This requires a relicense of Utility as LGPL. All classes moved into
this library from src/libsync will need to be relicensed as well.
This will allow us to unify data structures between csync and libsync.
Utility functions like csync_time and c_std are still compiled as C
since we won't need to be coupled with Qt in the short term.
