[pseudo] pseudo_util: Add log severity flags

From: Dmitry Sakhonchik <frezidok1@gmail.com>

Create an infrastructure to make use of severity flags from pseudo_tables.
After that it is now possible to set severity flags from env (PSEUDO_SEVERITY) and from terminal via optargs.

In the above string, the letters should be in alphabetic order.  So the new line 
should be:

+BCdfhi:klm:M:p:P:r:R:St:vVx:

I've no objections to 'k'.  We're out of easily letters at this point.. :(
