Missing parameter in glibc probe points

Issue

• Backport the code to allow for incremental loading of the library list.
• map_complete and reloc_complete have two arguments rather than the three documented in elf/rtld-debugger-interface.txt
• The functionality implements a critical pointer that keeps programs from having to reparse the link map on every library load.
• This has a mesurable impact on the performance of a program and especially HPC clusters as a whole.
