5d7f2fdf16 Fix loading of ET_DYN type of shared objects
* build-globals.sh
  - Only look in the nuttx for external symbols used when loading
    dynamic shared objects

* include/elf64.h
  - Correct the type of fields in the Elf64_Phdr structure

* libs/libc/dlfcn/lib_dlclose.c
  - Distinguish between ET_DYN and other objects as the former
    has both text and data in a single allocation to reserve
    GOT offsets

* libs/libc/dlfcn/lib_dlopen.c
  - Code formatting

* libs/libc/modlib/modlib_bind.c
  - Distinguish between relocation entry sizes by section type
  - Handle RELA style relocations

* libs/libc/modlib/modlib_globals.S
  - Formatting fixes
  - Symbols should not be weak - they exist or they don't

* include/nuttx/lib/modlib.h
  - Add an inidcator to module_s to distinguish between ET_DYN and other

* libs/libc/modlib/modlib_load.c
  - ET_DYN objects need to keep the relative displacement between the text
    and data sections due to GOT references from the former to the latter.
    This also implies that linking may require modification from the default
    for the shared objects being produced. For example, default alignment may
    mean nearly 64K of wasted space.

* libs/libc/modlib/modlib_unload.c
  sched/module/mod_rmmod.c
  - Distingusih between freeing of ET_DYN storage and other as the former
    is a single allocation.

* libs/libc/modlib/mod_insmod.c
  - Cater for ET_DYN objects having init and preinit sections

418e11b8b3 modlib: Always use separate allocation for text and data
Pros:

* Reduce code differences
* Smaller allocations for !CONFIG_ARCH_USE_MODULE_TEXT

Cons:

* Likely to use more memory for !CONFIG_ARCH_USE_MODULE_TEXT in total

Tested with:

* sim:module on macOS
* esp32-devkit:nsh + CONFIG_MODULE on qemu
* lm3s6965-ek:qemu-protected + CONFIG_EXAMPLES_SOTEST on qemu

51490bad55 modlib: Implement sh_addralign handling
I've seen a module with 16 bytes .rodata alignment for xmm operations.
It was getting SEGV on sim/Linux because of the alignment issue.
The same module binary seems working fine after applying this patch.

Also, tested on sim/macOS and esp32 on qemu,
using a module with an artificially large alignment. (64 bytes)

81f1133174 ELF64 support (#220)
* include: Introduce elf64.h and elf.h

    Added elf64.h for 64bit ELF support and moved common definitions
    from elf32.h to elf.h. Also introduced Elf_xxx to be used in
    common libraries such as binfmt.

  * binfmt, include, modlib, module: Add support for ELF64

    Elf_xxx must be used instead of Elf32_xxx to support ELF64.
    To use ELF64, CONFIG_ELF_64BIT must be enabled.

  * binfmt, modlib: Add support for relocate address

  * arch: risc-v: Add include/elf.h

  * libs: machine: Add risc-v related files.

    NOTE: Currently only supports ELF64

  * boards: maix-bit: Add elf and posix_spawn configurations

  * boards: maix-bit: Add support for module configuration

6a3c2aded6 Fix wait loop and void cast (#24)
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
