Uses/iconv.mk: Set iconv-related CMake variables.

The way we deal with iconv in base and ports across different FreeBSD
releases is complicated: 9.x does not have iconv.h in base, 10.1 has it with
a different prototype for iconv(3) and later versions have the right
iconv(3) prototype. And, in some cases (USES=iconv:{translit,wchar_t}), we
must always use the libiconv port.

This is why there are so many checks in Uses/iconv.mk: we need to know the
situation we currently have in order to decide whether to pull iconv from
converters/libiconv, whether to just use its header (and pull the library
from base) or whether to use everything from base.

r384038 adjusted several CMake-based ports, but did so in a way that was not
very scalable and required a few intrusive patches to some ports. Most ports

converters/libiconv:
- Remove const qualifier from iconv(3) to match POSIX:
  http://pubs.opengroup.org/onlinepubs/9699919799/functions/iconv.html
- Patch iconv.h to expose more GNU extensions when LIBICONV_PLUG is
  defined because the base system iconv supports these extensions too.

Add/remove patches to/from ports to call iconv with non-const arguments.

This breaks some ports on FreeBSD 10 because base system iconv.h still has
the const qualifier.  Fix this by letting USES=iconv add a build dependency
on converters/libiconv so ports can use its iconv.h (with LIBICONV_PLUG
defined) instead of the base system iconv.h.

This exposed some ports that link with libiconv when it is available instead
of using libc iconv.  In these cases one of the following changes has been
