Eric Pouech 5477ee640b dbghelp: Fix vdso.so lookup.
- should have been fixed when libwine.so has been removed
- code was broken anyway
- enhanced protect against error when reading debuggee's memory

Introducing helper to correctly read pointer's from debuggee
(and other integral values).

vdso is now listed in ELF's module list (except if Wine's preloader
removes it from auxilary vector)

/* Understanding functions internal storage:
* - functions, inline sites and blocks can be described as spreading across
* several chunks of memory (hence describing potentially a non contiguous
* memory space).
* - this is described internally as an array of address ranges
* (struct addr_range)
*
* - there's a hierarchical (aka lexical) relationship:
* + function's parent is a compiland or the module itself
* + inline site's parent is either a function or another inline site
* + block's parent is either a function, an inline site or another block.
*
* - internal storage rely on the following assumptions:
* + in an array of address ranges, one address range doesn't overlap over
* one of its siblings
* + each address range of a block is inside a single range of its lexical
* parent (and outside of the others since they don't overlap)
* + each address range of an inline site is inside a single range its
* lexical parent
* + a function (as of today) is only represented by a single address range
* (A).
*
* - all inline sites of a function are stored in a linked list:
* + this linked list shall preserve the weak order of the lexical-parent
* relationship (eg for any inline site A, which has inline site B
* as lexical parent, A must appear before B in the linked list)
*
* - lookup:
* + when looking up which inline site contains a given address, the first
* range containing that address found while walking the list of inline
* sites is the right one.
* + when lookup up which inner-most block contains an address, descend the
* blocks tree with branching on the block (if any) which contains the given
* address in one of its ranges
*
* Notes:
* (A): shall evolve but storage in native is awkward: from PGO testing, the
* top function is stored with its first range of address; all the others
* are stored as blocks, children of compiland, but which lexical parent
* is the top function. This breaks the natural assumption that
* children <> lexical parent is symmetrical.
* (B): see dwarf.c for some gory discrepancies between native & builtin
* DbgHelp.
