Subject: core: adding a mutex as a protected member of gr_block for use in
protecting set and work function access to variables.
This is used in gr-analog's noise_source and gr-filter's fir_filter_XXX since these two cause particular problems (in next's channel model). This shows the use of the mutex for general protection when needed.
