Add Mk/Uses/alias.mk

When on used FreeBSD, this tool doesn't do anything.  However, when used
on DragonFly, it will define __FreeBSD__ appropriately in CFLAGS which
allows the port to build with minimal or no extra patches.

Add USES=alias to several ports

Alias is a new USES tool that allows DragonFly to masquerade as FreeBSD
by setting CFLAGS+= -D__FreeBSD__.  For some ports, this fixes the build
without the need for additional patches.

games/warsow: Add USES=alias plus...

While adding USES=alias to warsow under blanket permission, I decided
to bring in other changes from DPorts:
  * define LDFLAGS=-L${LOCALBASE}/lib (required for compilers that don't
    search /usr/local/lib by default)
  * Only change x86_64 arch if the OPSYS is FreeBSD.  Doing this breaks
    DragonFly

The total sum of these changes for FreeBSD is no-op.
Update to 0.48.5.

Adobe Illustrator SVG files containing entities can be loaded again
Support for Poppler 0.26
Support for Boehm-GC 7.4.0 and later
Several crash bugs were fixed

Remove the gnomevfs option.

multimedia/mlt: add USES=alias plus ...

USES=alias allows the port to build on DragonFly without patches, but
only if --target-os=FreeBSD is also sent to the configure script.  This
is a no-op for FreeBSD (configure eventually sets target-os to FreeBSD
anyway).  USES=alias was covered by portmgr blanket.
- Fix format:
  - Add blank line
  - Remove trailing space
