Michael Paquier ddbd5d8731 Add to pageinspect function to make t_infomask/t_infomask2 human-readable
Flags of t_infomask and t_infomask2 for each tuple are already included
in the information returned by heap_page_items as integers, and we
lacked a way to make that information human-readable.

Per discussion, the function includes an option which controls if
combined flags should be decomposed or not.  The default is false, to
not decompose combined flags.

The module is bumped to version 1.8.
