volk: commit the super squash (volk dir only changes)
volk: convert kernels one last time, removed old kernels

Please use the new kernel style in kernels/volk.
One file with both generic, and possibly aligned and unaligned implementations.
The kernel may have a custom dispatcher.
See kernels/README.txt

Examples: Fixed minor bugs in examples and blks2impl from namespace changes.
cmake: copy stdbool for gnuradio as well
wavelet: fix API export declarations
qtgui: fix log10 ambiguous overload in DisplayPlot
core: dont export totally inline classes

These classes have no symbols actually grounded in the core library.
Due to this exporting the class seems to confuse MSVC.
Commenting out GR_CORE_API makes MSVC and gcc happy.
filter: moving filter design tool from gr-utils to gr-filter.
digital: Fixes LMS and CMA equalizers.

filter: updated fir_filter_* by adding a method that allows the update of a single tap in the filter in a way that propagates to all of the aligned tap vectors. Mostly to support the adaptive equalizers.
