8720f42b33 examples: Update gpio example 
The example assumed that there was always at least one TX and on RX
channel.  Since that is not always true, this change checks for TX
and RX channels and only exucutes tests for what exists on the device.

Applied clang format.

Note: template_lvbitx.{cpp,hpp} need to be excluded from the list of
files that clang-format gets applied against.

d7304cc724 x300: add front-panel GPIO source control 
Adds a ZPU register to control the FP GPIO source. These are 2bits
per GPIO pin, totalling 24 bits. 0 corresponds to RF-A, 1 corresponds
to RF-B. The following Python code will control the upper 6 bits of the
front-panel GPIO from the B-side radio on an X300:

>>> import uhd
>>> U = uhd.usrp.MultiUSRP("type=x300")
>>> U.get_gpio_src_banks()
['FP0']
>>> U.get_gpio_src("FP0")
['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA',
'RFA', 'RFA']
>>> U.set_gpio_src("FP0", ['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA',
                           'RFB', 'RFB', 'RFB', 'RFB', 'RFB', 'RFB'])
>>> U.get_gpio_src("FP0")
['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFB', 'RFB', 'RFB', 'RFB',
'RFB', 'RFB']
>>> # Make all GPIOs outputs:
>>> U.set_gpio_attr("FP0A", "DDR", 0xFFF)
>>> U.set_gpio_attr("FP0B", "DDR", 0xFFF)
>>> # Control all GPIOs from software (not ATR):
>>> U.set_gpio_attr("FP0A", "CTRL", 0x000)
>>> U.set_gpio_attr("FP0B", "CTRL", 0x000)
>>> # Bottom 3 pins go high from radio A
>>> U.set_gpio_attr("FP0A", "OUT", 0x007)
>>> # Top 3 pins go high from radio B
>>> U.set_gpio_attr("FP0B", "OUT", 0xE00)

Amends the gpio.cpp example to allow switching the source.

91f8a9b8b2 examples: gpio: Replace get_time_now() with steady_clock::now() 
The gpio example would continously call get_time_now() to time a loop.
There is no need to query a device here, so we query the system timer
instead.

This fixes an issue where the large amounts of control traffic could
slow down TX, causing the TX and FDX tests to fail. This was only ever
seen on the X300_HG over 1GigE.

60a70f7142 examples: remove thread priority elevation 
Remove UHD call to elevate thread priority to realtime. Setting all
threads to the same realtime priority can cause the threads to not share
access to the network interface fairly, which adversely affects
operation of the worker threads in UHD.

967be2a4e8 uhd: mpm: apply clang-format to all files 
Applying formatting changes to all .cpp and .hpp files in the following
directories:
```
find host/examples/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find host/tests/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find host/lib/usrp/dboard/neon/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find host/lib/usrp/dboard/magnesium/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find host/lib/usrp/device3/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find host/lib/usrp/mpmd/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find host/lib/usrp/x300/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find host/utils/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
find mpm/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
```

Also formatted host/include/, except Cpp03 was used as a the language
standard instead of Cpp11.
```
sed -i 's/ Cpp11/ Cpp03/g' .clang-format
find host/include/ -iname *.hpp -o -iname *.cpp | \
    xargs clang-format -i -style=file
```

Formatting style was designated by the .clang-format file.

601e0ed87b examples: utils: skip formatting program options 
Turning off clang formatting around the program option declarations.
clang-format makes them looks bad an unreadable because it thinks the
options are function calls or something.

99c2730bc9 Remove all boost:: namespace prefix for uint32_t, int32_t etc. (fixed-width types) 
- Also removes all references to boost/cstdint.hpp and replaces it with
  stdint.h (The 'correct' replacement would be <cstdint>, but not all of our
  compilers support that).
