Currently all usage of struct qmi_elem_info, which is used to define
the QMI message encoding/decoding rules, does not use const. This
prevents clients from registering const arrays. Since these arrays are
always pre-defined, they should be const, so add the const qualifier
to all places in the QMI interface where struct qmi_elem_info is used.
Once this patch is in place, clients can independently update their
pre-defined arrays to be const, as demonstrated in the QMI sample
code.

Add the helper library for encoding and decoding QMI encoded messages.
The implementation is taken from lib/qmi_encdec.c of the Qualcomm kernel
(msm-3.18).
Modifications has been made to the public API, source buffers has been
made const and the debug-logging part was omitted, for now.
