perf gtk/browser: Convert hpp helpers to a function

Browse Source 
The hpp helpers do same job for each field so it was implemented as
macro in order to access those fields easily.  But it gets cumbersome to
maintain a large function in a macro as the function grows. Factor it
out to a function with a little helper macro to access field.
