Work in progress, incomplete
* Renamed noaa.carrier_pll_cc to noaa.hrpt_pll_cc
* Added nop noaa.hrpt_sync_cc
* Renamed grc apps to use usrp_ prefix and protocol name
* Installed grc generated scripts to path

Created new gr-noaa top-level component.
Initial work:
- Carrier recovery/mixer PLL block
- Start of POES grc pipeline, recovers Manchester symbols only
- Start of GOES grc pipeline, recovers BPSK symbols only
Used blks2.cvsd* wrappers, not bare gnuradio.vocoder.cvsd*
Example application sweeps 0-4KHz through encoder/decoder pair configured
as Bluetooth standard
Re/evaluate the notebook blocks label because we dont garuntee the evaluation priority.
Meaning, we cant garuntee that the notebook block will be evaluated before this param,
without explicitly calling evaluate on it when the value is needed.

Add rxdspno parameter to private interface of quadradio.
This allows control of each Rx DSP pipeline independent of each other.
The public interface remains unchanged, but should have the rxdspno
parameter added as indicated in the FIXMEs. When that is done, the
gr-vrt interface (and any code using it) will need to be updated too.

configure.gnu needs to unset more vars from the environment.
This solves a problem running the usrp2/firmware configure script
when the USB_* vars are set in the environment. Long term fix is
to have the configure.gnu wrapper make sure the quoting is OK for vars
passed on.
Merge branch 'utils' of http://gnuradio.org/git/trondeau into master
* 'utils' of http://gnuradio.org/git/trondeau:
Fixed slider behavior when the end of the file is reached.
Handling a few exceptions when no file is loaded.
Can now change the size of the symbols. Also fixes some layout issues.
Adding ability to change line width and style (only a handful of current styles enabled).
Removing plot picker that addd nothing to the interface.
Adding a Reload option (Ctrl+R) option to quickly reread the file and reset the state.

Applied libusb-1.0 patch set from Thomas Tsou <ttsou@vt.edu>:
This patch set updates the usrp to support libusb-1.0. Asynchronous I/O
through libusb is added with fusb_libusb1.*, which is heavily based on
fusb_linux.*. In short, URB's and ioctl calls are replaced with
libusb_transfer structs and native calls. Transfer reaping is handled by
libusb and associated callbacks. I get 32Mb/s on all of my machines using
test_usrp_standard_rx or tx. Due to the API rewrite in 1.0 from 0.12, there
are alot of changes, many are simply name changes.
Known Issues:
Transmit and receive both work, but not at same time
(e.g. usrp_benchmark_usb.py). libusb does not create any internal threads,
so for a single session fusb_libusb1 works in the same manner as
fusb_linux with the callback called at controlled times. With multiple
libusb sessions the callback may occur at any time and threading issues
come into play causing behavior to become undefined. The use of separate
libusb_contexts _might_ solve this issue; I have not had the time to look
into it.
Merge branch 'grc' of http://gnuradio.org/git/jblum into master
* 'grc' of http://gnuradio.org/git/jblum:
fixed issue where entry boxes lost focus (mishandling of hide changing)
fixed bool converter in forms to work with non bool options
tweaked key handling callbacks
fix for uniformity convention with gtk signal name strings
Simply Actions module imports, using module prefix.
Reworked actions api and actions objects:
Move key press extraction logic into actions module.
rename variable, use keysyms in props dialog
use the keymap's translate_keyboard_state, use the key value rather than name
ignore irrelevant modifiers and events pending
properties dialog with ok/cancel buttons
Reworked actions api and actions objects:
Created standardized Action object for all gui actions.
Actions module constants are actual Action objects (not strings).
Keypresses, labels, tooltips, stock icons, etc all associate in the Action constructor.
Usage of the action's signaling call () eliminated the need for a reference to handle_states.
Move key press extraction logic into actions module.
Replaced xml encode with gtk escape text.
Added templates for category and docs tool tips.
Other various code tweaks in gui modules.
Merge branch 'grc' of http://gnuradio.org/git/jblum into master
* 'grc' of http://gnuradio.org/git/jblum:
use show signal to perform initial gui update
Fixed the usrp and usrp2 probe scripts to work with the new gui param api.
propsdialog tweaks
more code cleanup for properties dialog
Rework the params/properties dialog and param gui class:
renamed params dialog to props dialog
remove unused imports, copyright date update, tweak
Created recursive create labels and shapes method for gui element.
replaced dict[rot] storage of areas and lines with a single list for the current rotation
standardized the Element inheritance __init__ usage in gui
better error msg for empty statements
Implement a recursive validation api in the base Element class.
Merge branch 'usrp_siggen' of http://gnuradio.org/git/jblum into master
* 'usrp_siggen' of http://gnuradio.org/git/jblum:
only import usrp and usrp2 modules in the setup methods
updated digital to use installed usrp options
tweaked ampl slider params
copied usrp_siggen stuff from experimental gui into gnuradio tree
Round the slider's value, but not the internal representation.
Now, the slider can operate on any step size without killing the precision for other forms.
Fixed the usrp and usrp2 probe scripts to work with the new gui param api.
Also fixed the scripts to work since they were broken by previous changes.
Get input in param class now pases a param instance (self) into the object.
Created recursive create labels and shapes method for gui element.
Replaces update methods in the gui classes and simplifies calls.
The master update method in flow graph calls create labels and shapes.
Implement a recursive validation api in the base Element class.
The rewrite and validate methods will invoke themselves on the child elements.
The error messages are now a super-list of element and child error messages.
As a side-effect, this cleans up code in base Block and Flowgraph class.

Implement Eth flow control using pause frames
Not fully tested, but it seems to work without frame errors, sequence
number errors or ethernet overruns. Still of course will get tx underruns
on a slow machine, and the transmitted signal has some issues though.
