Mountbroker is configured in glusterd volfile through a DSL
which is restriced enough to be able to appear in the role
of the value of a volfile knob.
Basically the DSL describes set-theorical requirements
against the option set which is sent by the cli (in the
hope of getting a mount with these options).
If the requirements meet and the volume id and the uid
who is to "own" the mount can be unambigously deduced from
the given request, glusterd does the mount with the given
parameters.
The use case of geo-replication is sugared by means of volume
options which then generate a complete mount-broker option set.
Demo:
- add the following option to your glusterd volfile:
option mountbroker-root /tmp/mbr
option mountbroker.fool EQL(volfile-id=pop*|user-map-root=*|volfile-server=localhost)&MEET(user-map-root=john|user-map-root=jane)
- before starting glusterd, create /tmp/mbr owned by root with mode 0755
- with cli, do
$ gluster system:: mount fool volfile-id=pop33 user-map-root=jane volfile-server=localhost
- on succesful completion (volume pop33 exists and is started, jane is a valid username),
the mount path will be echoed to you
- you can get rid of the mount by
$ gluster system:: umount <mount-path>

This fixes ~200 such warnings, but leaves three categories untouched.
(1) Rpcgen code.
(2) Macros which set variables in the outer (calling function) scope.
(3) Variables which are set via function calls which may have side effects.

The header of the ptr returned from mem-pool will now store the
mem-pool ptr it belongs to. mem_put will now take only the pointer
to be freed.
Also, changing MALLOC call to GF_CALLOC in mem_get when we run out
of entries in mem-pool. This also will have the header information
saved.

NetBSD's <dirent.h> does a #defiine d_ino d_fileno. Since glusterfs
declares structs with d_ino members, we must include <dirent.h> early
so that d_ino get preprocessed into d_fileno conssitently.
Also define proper xdr types for NetBSD.

NetBSD does not have AI_ADDRCONFIG. This patch has a side effect: glusterfsd
listens on IPv6 adresses only by default. Option transport.socket.bind-address
in volume server-tcp must be used to listen on an IPv4 address.

Allows glusterfs clients to bind to any port and does not restrict it
to 1024.
This is a xlator-option only, and is not supported in volume set cmd.
The reason is, few clients may choose this, and few may not. Hence
only supported as a xlator-option during mount time.
For this to work with glusterfs, server.allow-insecure should be set
to on
