nuttx/libs/libc/modlib/modlib_x64_globals.S
Neale Ferguson fec789047a Add support for the loading of ET_DYN objects 
* libs/libc/machine/arm/armv7-m/arch_elf.c
      - Fix cast of error message parameters

    * build-globals.sh
      - Build the modlib_globals.S file used to resolve symbols when dynamically loading

    * libs/libc/modlib/Make.defs
      - Build modlib_globals.S for all targets

    * libs/libc/modlib/modlib_load.c
      - Calculate sizes and text/data addresses based on program headers rather than section headers
      - Handle objects with no program headers

    * libs/libc/modlib/modlib_bind.c
      - Call modlib_readsym with pointer to symbol table
      - Add modlib_relocatedyn to manage relocation of symbols with shared object (ET_DYN)
      - Differentiate between ET_REL and ET_DYN objects
      - Use arch independent symbol ELF_R_SYM
      - Cast sizes to avoid warnings

    * libs/libc/modlib/modlib_load.c
      - Cast sizes to avoid warnings

      - Define Elf_Dyn and Elf_Off according to the elf architecture
      - Add fields to mod_loadifno_s:
        - Program headers
        - Exported symbols
        - Data section address
        - Padding requirement
        - Section index for dynamic symbol table
        - Number of symbols exported
      - Add prottotype for modlib_freesymtab

      - Add dump of program headers to debug routine
      - Differentiate between ET_REL and ET_DYN objects

    * libs/libc/machine/arm/armv7-m/arch_elf.c
      - Add handling of R_ARM_RELATIVE and R_ARM_JUMP slot relocation types

    * libs/libc/modlib/modlib_loadshdrs.c
      - Rename modlib_loadshdrs.c to modlib_loadhdrs.c
      - Rename modlib_loadshdrs to modlib_loadhdrs
      - Add code to load program headers

    * libs/libc/modlib/modlib_symbols.c
      - Define entry point structure
      - Add offset parameter to modlib_symname() and use to find symbol names
      - Add symtab section header parameter to modlib_readsym()
      - Add offset parameter to modlib_symvalue() to locate symbol names
      - Add modlib_insertsyntab() to create a symbol table for exporting and resolution
      - Add findEP() to resolve a symbol in the modlib_global table
      - Add modlib_findglobal() to find symbol in the modlib_global table
      - Add modlib_freesymtab() to free the symbol table

    * libs/libc/modlib/modlib_uninit.c
      - Free header and sections from a module_loadinfo_s control block

    * libs/libc/modlib/modlib_verify.c
      - Handle ET_DYN shared objects

    * libs/libc/modlib/modlib_globals.S
      - Multi-target global table
      - Define library APIs that may be resolved when loading a shared object
