corrected a mistake that blocked compilation(from last commit at shminfo initialization),
removed the options from USAGE in the manpage and the program ,since it's too bloated to be usefull

libjack is dlopened so there's no runtime dependency on it. Ports must be connected at startup.

and thus require sufficiently less hard disk space.
Instead of the old (plane_width/16)*(plane_height/16) blocksize,
now we are using 16x16 for the y plane and 8x8 blocks for the u,v planes.
Also this byte alignment allows comparing of blocks to happen by
first casting into a larger datatype(u_int64_t if available, u_int32_t else).
This way we do as little as 1/8 or 1/4 of comparisons. This essentially offsets
the higher CPU required to check the now increased number of blocks, and even
provides a slight performance boost from the previous way of caching.
Also, the load cache loop has been debloated, by moving much of the functionality
that previously resided in an if evaluation statement, into anew function(ReadFrame).
For further abstraction, ReadFrame utilizes ReadZF to do the actual reading.
ReadZF determines if a gzread or an fread has to be done.
Another improvement in the program is that, now, write operations on the disk, happen
in 4 kbytes pages, minimizing thus the overall cost of access.
Last change in this set is that the indexes in the CachedFrame and FrameHeader datatypes,
are now u_int32_t's, to accomodate the possibly large number of blocks(could have been 16 bit
types but that would give 4096*4096 max resolution, which might have caused problems in the future)

(rule is purely for visual purposes, macro expansions are not taken into account).

which have been replaced with UPDATE_*_PLANE(S) with an extra __bit_depth__ parameter

Currently the UPDATE_*_PLANE(S)_* macros are duplicated, so they might need some
reworking (they are perfectly functional though).

This one is further broken into UPDATE_(X)_PLANE(S)_(Y) macros, where X is Y or UV and Y is 32 or 16(color depth).
This will allow easier incorporation of 16bpp support, without code duplication(where it can be avoided) and
without bloating the toplevel calls of these macros with multiple similar blocks of code.
Also changed toplevel check of depth, to allow running on 16 bpp

with sizeof(long)!=4). Xfixes.h declares the pixels as a list of unsigned long
instead of CARD32 that is used on the serverside , resulting in 4 byte padding on amd64,
where sizeof(long)==8.This was breaking the XFIXES_POINTER_TO_YUV macro, but is now corrected.
