36c39678d6 Fix a bug that prevented applications from laying out ELF objects
with section header tables residing in between other sections.

Introduce additional checks for overlaps between section data and
the section header table when the application is performing section
layout.

Document additional error returns.

f6c0f35e07 Keep shadow copies of the e_shnum', e_phnum' and `e_shstrndx'
members of the ELF Executable Header inside the library-private
`struct _Elf' descriptor and only update the underlying Elf{32,64}_Ehdr
structure on an elf_update(3) call.  These fields of the Ehdr
structure are technically `out of bounds' for an application program
per the ELF(3) API, but we've seen applications that initialize
a new Ehdr structure using memcpy(), messing up the library's
invariants. [1]

Implement elf_getphnum() and handle ELF objects with more than
64K program header table entries.
