  Log Message:
  -----------
  [yaml2obj/obj2yaml] - Improve dumping/creating of ELF versioning sections.

This makes the following improvements.

For `SHT_GNU_versym`:
 * yaml2obj: set `sh_link` to index of `.dynsym` section automatically.
For `SHT_GNU_verdef`:
 * yaml2obj: set `sh_link` to index of `.dynstr` section automatically.
 * yaml2obj: set `sh_info` field automatically.
 * obj2yaml: don't dump the `Info` field when its value matches the number of version definitions.
For `SHT_GNU_verneed`:
 * yaml2obj: set `sh_link` to index of `.dynstr` section automatically.
 * yaml2obj: set `sh_info` field automatically.
 * obj2yaml: don't dump the `Info` field when its value matches the number of version dependencies.

Also, simplifies few test cases.
