Update naming standards to avoid hungarian notation in C++

Update naming standards to avoid hungarian notation in C++

Our coding standards still contained lines specifying hungarian
notation for boolean and enumerated types, which is mostly a remnant
from our (really) old C practice. While apps hungarian might provide
some safety (i.e., using one prefix for rows and another for columns),
there is little or no value in systems hungarian where the prefix
is just based on type - in particular when we frequently assign
variables between those types. This recommends us to use long
descriptive names instead, including a verb for boolean variables.
When we eventually get C++11 support we should switch to class enums
to have the compiler to more checking, but that is not yet possible.
