1) Except for compatibility code which does not concern us here,
'initial_value' is only needed in Pari.xs:installep() 
( a copy of an old version of the identically named static routine in anal.c).

This is then used in PARIvar, findVariable: can't you use fetch_named_var()
in there ?

2) bl_prev() is required in dumpHeap in order to traverse the linked
list of PARI 'blocs' which are neither documented, nor accessible.

I can provide a public routine

  traverseheap( void (*f)(void *D, GEN x), void *data )

that would successively apply f(data, x) to each GEN x in the PARI heap,
starting from the most recent one.

Would that be suitable ?

Cheers,

    Karim.
