grab bag of fixes required for IPP-2.4 to build on Macs

[jester@…]

From Mark Huber's email to ps-ipp-users on 27/02/2008,

psLib/src/math/psUnaryOp.c, psBinaryOp.c - needed <strings.h> included

psModules/src/objects/pmSource.c - needed <strings.h> included

psastro/src/psastroModelDataLoad.c - needed <strings.h> included in psastroStandAlone.h

The following is a result of the problems with KAPA (is that still turned off on Macs by hand? If so, why? see bug 892...)

psastro/src/psastroDemoPlot.c - re-declaration of psastroPlotRawstars,...Refstars,...OneChipFit

in psastro.h. i made a separate psastro.h with those prototypes commented out.

The problem is simply that the #else branch needs the prototypes to include

psMetadata *recipe

as last argument (starting in line 476), and psastroPlotOneChipFit doesn't need the

pmAstromFitResults *results

any more.

This fixes all these problems. I still have a HAVE_PSDB one...
