r210344:
  Avoid switching between "unsigned char" and "char" in the C code
  generated from "libelf_convert.m4".

r210345:
  * Deprecate `elf_getshnum()`, `elf_getphnum()` and `elf_getshstrndx()` in
    favour of `elf_getshdrnum()`, `elf_getphdrnum()` and `elf_getshdrstrndx()`
    respectively.
  * Add new manual pages for `elf_getshdrstrndx()`, `elf_getphdrnum()` and
    `elf_getshdrnum()`.
  * Add a deprecation warning for `elf_getshstrndx()`, `elf_getphnum()` and
    `elf_getshnum()`.

r210348:
  Move helper functions `_libelf_ar_get_{name,number,string}()` and
  `_libelf_ar_open()` to a new compilation unit "libelf_ar_util.c"
  to break the circular dependency between "elf_memory.o" and
  "libelf_ar.o".

Don't need to set symbol, default value is OK.

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.

Use rather than the OS version reported by the kernel

to determine which Elf Types are to be handled.  Change the M4
templates to wrap an `#if __FreeBSD_version >= NNN'/`#endif' pair
around the generated code for each ELF data type, where `NNN' is
the OS version where the ELF type was added to the source tree.

This change allows cross-builds of old sources on newer FreeBSD
systems to work correctly.

Problem reported by:	ru

- style: use `=' instead of `+=' for initial assignments.

- don't add generated sources' objects to OBJS explicitly;
  GENSRCS is part of SRCS so they were already in OBJS.

- Replace the use of DPSRCS with something more appropriate. DPSRCS

  is for when you need something in ".depend", but not compiled in.
- Style fixes: Spell ${.OBJDIR} as ".".
- Neaten a comment.
