core: heketi-cli is throwing error "target is busy"

Problem: When rpc-transport-disconnect happens, server_connection_cleanup_flush_cbk() 
         is supposed to call rpc_transport_unref() after open-files on 
         that transport are flushed per transport.But open-fd-count is 
         maintained in bound_xl->fd_count, which can be incremented/decremented 
         cumulatively in server_connection_cleanup() by all transport 
         disconnect paths. So instead of rpc_transport_unref() happening 
         per transport, it ends up doing it only once after all the files 
         on all the transports for the brick are flushed leading to 
         rpc-leaks.

Solution: To avoid races maintain fd_cnt at client instead of maintaining
          on brick

libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.
