[Patch-gnuradio] Patch for gri_glfsr.h

[Eudean Sun]

I have a short patch for gri_glfsr.h. I haven't filled out a copyright
form but this is very short so hopefully it won't be an issue.

Description of bug:

In file gnuradio-core/src/lib/general/gri_glfsr.h, the variable
d_shift_register is declared as a signed integer. When right shifted in
function next_bit(), this produces an arithmetic instead of a logical
shift, which gives incorrect results. Fixed by making d_shift_register and
d_mask unsigned integers.

Also in this file, the constructor should use an initialization list to
initialize the member variables.

ChangeLog entry:

Changed d_shift_register and d_mask from signed to unsigned. Moved member
variable initialization from constructor body to initialization list.

Patch is attached.
