The contrib/top code is no longer maintained upstream (last pulled 16 years
ago). The K&R-style followed by the code spews -Wimplicit-int and -Wreturn-type

as possible by adding necessary return types, definitions, headers, and header
guards, and missing header includes.
The 5 warnings that remain are due to undeclared ncurses references. I didn't

Make __FreeBSD_cc_version predefined macro configurable at build time
The `FreeBSDTargetInfo` class has always set the `__FreeBSD_cc_version`
predefined macro to a rather static value, calculated from the major OS

In the FreeBSD base system, we will start incrementing the value of this
macro whenever we make any signifant change to clang, so we need a way
to configure the macro's value at build time.
Use `FREEBSD_CC_VERSION` for this, which we can define in the FreeBSD
build system using either the `-D` command line option, or an include
file. Stock builds will keep the earlier value.

Merge ELF Tool Chain r3434:
Previously, elfcopy defines:
VMA: section virtual address
LMA: PHDR(p_vaddr)
While binutils(libbfd) defines:
VMA: section virtual address and PHDR(p_vaddr).
LMA: PHDR(p_paddr)
For elfcopy, p_paddr is considered not meaningful and is always set
to the same value as p_vaddr.
elfcopy was implemented that way because I thought p_paddr is not
used/meaningful according to the ELF ABI. However it turned out
p_paddr is at least used in some ELF files, e.g. the FreeBSD kernel.
This change made elfcopy treat p_paddr as LMA, same as libbfd.
(However, some VMA/LMA related command line option still need tweaking
to make them compatible with binutils objcopy. This will be improved
later)

1. Turn on variable templates. (Uses __cpp_variable_templates)

3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)

config. The change for that ended up removing __sdp_sockaddr_to_sdp
which the IPV4 config code required; the IPv6 fix resolved the lack of
that symbol.
Note that the ChangeLog was lacking entries for which we already had the
changes for, which itself was an upstream bug.

When the armv6 support was imported from a project branch, this complex
conditional logic and related #define'd values came along, but it's really
not clear what the intent of it all was. The effect, however, was that
OSABI was always set to zero, which is "UNIX System V ABI". Having the wrong
value there causes pkg(8) to avoid looking inside arm elf binaries to
determine shared-lib required/provides info for packaging.
If the output object is not an ELF file, choose an arbitrary ELF format
