Fix build after LibV4L upgrade to v1.18.0.

Approved by:	pi (implicit)

Bump PORTREVISION to chase update of multimedia/v4l_compat and libv4l

multimedia/w_scan: update to 20170107, which adds support for DVB-T2

- take maintainership
- drop LINUX option, the Linux binary is no longer pre-shipped
- pet portlint

Remove libiconv.so.3 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

- Replace Mk/bsd.linux-apps.mk and Mk/bsd.linux-rpm.mk with
  Mk/Uses/linux.mk.
- Replace USE_LINUX=yes with USES+=linux and USE_LINUX=(.*) with
  USES+=linux:\1 in all ports.
- Replace USE_LINUX_APPS with USE_LINUX in all ports.
- Use INSTALL_SCRIPT instead of INSTALL_PROGRAM to install scripts in some
  ports.
- When USE_LINUX_RPM is defined, simplify the way DISTFILES and EXTRACT_ONLY
  are defined.
- Remove BRANDELF_DIRS and BRANDELF_FILES handling.  In the very rare cases
  that it is still necessary ports can run ${BRANDELF} from post-patch.
- Remove AUTOMATIC_PLIST handling.  Only one port used it.
- Fix Linux MASTER_SITES.
- Replace OVERRIDE_LINUX_BASE_PORT and OVERRIDE_LINUX_NONBASE_PORTS with
  default versions framework.

With the power of USES=dos2unix, get rid of most patches and files
with CRLF.

While there, run make makepatch, rename patches to use the new scheme,
and various fixes.

Remove double quotes from OPTIONng *_DESC now that make showconfig
no longer needs them.

- Convert these to OPTIONng.
- Omit shlib major versions in LIB_DEPENDS to pet portlint.

Update to 20120415 .

- Update to 20111203 .
- Add knob to install the Linux version too (needs
  multimedia/linux_dvbwrapper-kmod kldload'ed to run.)
- Add workaround to avoid invalid UTF-8 encodings when converting
  from ISO_6937-2 (that the iconv used on FreeBSD doesn't know) -
  if you need ISO_6937-2 converted properly you have to use the
  Linux version for now.  (Tho all the 8-bit channel names I see
  here marked as the default ISO_6937-2 charset are in fact
  ISO8859-1(5) i.e. the charset isn't marked properly on those
  transponders and thus the Linux version would convert them wrongly
  too.)

Feature safe:   yes

Update to 20111011 .

- Add LDFLAGS to CONFIGURE_ENV and MAKE_ENV (as it was done with LDFLAGS)
- Fix all ports that add {CPP,LD}FLAGS to *_ENV to modify flags instead

[From the README:]

this is a small channel scan tool for vdr which generates ATSC, DVB-C,
DVB-S/S2 and DVB-T channels.conf files.
It's 50% "scan" from linuxtv-dvb-apps-1.1.0, the differences are:

- no initial tuning data needed, because scanning without this data is exactly
  what a scan tool like this should do
- it detects automatically which DVB/ATSC card to use.
