[lldb-dev] RFC: Namespaces in lldb

The initial developers of lldb-mi perhaps did not want to use the classes from
lldb_private inside lldb-mi. So in some cases, they sort of duplicated the code
for things like Mutex in lld-mi which are already available in host layer. If there
are no objections on using lldb_private inside lldb-mi then I can remove that
code duplication.
