Fix from zzam at gentoo.org for using relatively rarely used linker options.

Remove the ' interlacing' part of the message. It was apparently causing
problems when corrupt/invalid files were used with lav2mpeg

A smal fix to make the spect file compatibel with my versions of rpm gen process.

Move/add a pkg-config check to placate the gentoo folks

Core2Duo Intel cpus are 'pentium-m' NOT pentium3. using pentium3 will cause
gcc to crash on MacBookPro using a Core2 cpu.

trying to sqeeze the last bit of image quality out of it ...

Fix minor warning-generating errors in source-code.

Fix various initialisation bugs detected by valgrind in Pass-1 of
on-the-fly rate controller.
Switch on-the-fly rate controller to use the variance instead of old
DCT coefficient based 'activity metric' for rate control so rate control
can setup without all DCTs first having been done.
Fix a number of minor errors causing compiler warnings

Need to install mpeg2syntaxcodes.h and imageplanes.hh for compiling against
libmpeg2encpp.

Add to LIBLADD to work around a windows linker limitation.

Further finetuning

a) should run under OSX with Altivec-SIMD, now (Steven can you pls
check this?
b) should be a lot faster (time-recursive approach)
c) should be capable of giving the full vertical resolution ;-)
(it might however produce visable ghosts on scene changes, which
is not possible to come arround completely...)
