Use safer allocation routines in more places of the tree

Browse Source 
This is part of a more global effort to modernize the code tree with
safer allocation functions, which offer more protection in terms of:
- stronger type safety guarantees
- size overflow checks, particulary for arrays.

This set of updates includes allocation changes based on
palloc_object(), palloc_array() and repalloc_array().  This work is
similar to 1b105f9472, expanding more the new APIs in the tree in an
incremental fashion.
