lang/go14: Remove port

lang/go was switched to the new bootstrap and it was the only consumer of
lang/go14.

lang/go14: Don't install doc and test files

Currently, lang/go14 installs about 1,400-ish doc and test files.
The only role of go14 is to build lang/go, and those files have
no role in that.

lang/go14: update to go1.4-bootstrap-20171003

Build lang/go14 without SSE2

This allows to build lang/go14 on old x86 CPUs without SSE2 instructions.
This has an impact on generated machine code performance, but lang/go14
is only useful to boostrap lang/go so it is ok to do so unconditionally.

- Switch to new test framework

Approved by:	portmgr blanket

This built for me on the most recent armv7 run.  Let's try it on
the cluster on armv6 again.

Approved by:	portmgr (tier-2 blanket)

Mark more ports broken that fail on both armv6 and armv7.

Approved by:	portmgr (tier-2 blanket)

For ports that are explicitly enabled on armv6, also enable them
on armv7.  This has not been tested with an -exp run but should
"do no harm".

Sort ARCHS.  Pet portlint.

Scrub mention of armv6hf from ARCHS.  It was never in a released version.

While here, sort ARCHS and pet portlint.

- Fix shebangs
- Fix bin/rc in lang/go since we dont have it in base or a port to support it
- While in lang/go remove WRKSRC for SHEBANG_FILES
- Bump PORTREVISION for package change

Add two patches to lang/go14.

- patch-syscall

  Use SYSCALL assembly instead of INT 0x80 for syscalls on amd64.
  Using INT 0x80 as syscall gate on amd64 is an accidential and
  undocumented feature of COMPAT_FREEBSD32. It allows to use 64-bit
  ABI, but run syscalls through i386 gate.
  Go used this "feature" to workaround a bug in FreeBSD 8, which is no
  longer relevant.
  The patch is exact e9ce76b0eca8fa95dddb90b0a72aadab58de2ffc from go
  repo.
  Now lang/go14 doesn't need COMPAT_FREEBSD32 to build and run.

- patch-pipe2

  The pipe2 syscall is present in all supported versions of FreeBSD,
  but pipe was removed from FreeBSD 11. With the patch go14 can be
  built and run on a system without COMPAT_FREEBSD10.

Disable BROKEN for armv6.

Apparently the failure is only when running under emulation, and it
works fine on physical hardware.

Mark as broken on armv6 after recent runs.

lang/go14: allow building on armv6hf

Improve shebangfix framework

- Support multiple values in *_OLD_CMD, i.e. we can now fix both
"/usr/bin/python" and "/usr/bin/env python" at the same time
- Default *_OLD_CMD values are now always appended, so you don't need to specify
them in individual ports
- Add lua support (depends on USES=lua)
- Add more default values, such as "/usr/bin/env foo" for python, perl, bash,
ruby and lua
- Shebangfix now matches whole words, e.g. we will no longer (erroneously)
replace "/usr/bin/perl5.005" with "${perl_CMD}5.005" (but "/usr/bin/perl -tt" is
still (correctly) replaced with "${perl_CMD} -tt")

Note that *_OLD_CMD items containing spaces must now be quoted (e.g.
perl_OLD_CMD=/bin/perl /usr/bin/perl "/usr/bin/env perl")

Update shebangfix usage according to new rules in many ports:

- Remove *_OLD_CMD for patterns now replaced by default
- Quote custom *_OLD_CMD which contain spaces

Fix shebangfix usage in many ports (irrelevant to infrastructure change):

- Remove redundant SHEBANG_LANG (no need to duplicate default langs)
- Remove redundant *_CMD (such as
python_CMD=${LOCALBASE}/bin/python${PYTHON_VER} when USES=python is present)
- Never use *_OLD_CMD in REINPLACE_CMD matchers, these should always look for
exact string
