19991217: garp and next version of Gempak

Steve,

I've made a quick pass at compiling Garp with Mary's 5.4.3v N-AWIPS
distribution (which won't be released...but lets us know where things
are headed). 

Here are the basic porting issues:

SSTN calls changed (ispri argument added to call) in 5.4.3 gemlib.
These Garp routines are affected:
gempak/
psnprof.f:                      
psurf.f:                        
pupa.f:                       
wprofwnd.f:


XW image routines moved to gn library and renamed
(gempak/readimgdata.c)
xrarea --> crarea
xrgini --> crarea
xrnids --> crnids
xrnowr --> crnowr


Jim Cowie's image library variable changes are in 5.4.3 now, so no longer
a need to port back to our release.


GFLUSH routine eliminated from Gempak 5.4.2 and higher. No longer a need
to call GFLUSH in any routine - several instances in Garp commented out.


gempak/erwmsg.f changed calling sequence to ER_MMSG

 CALL ER_MMSG ( errgrp, numerr, errstr, .false., 
     +     outmsg, iret )


Addition text attributes added to 5.4.3 calls-
gqtext.f calling sequence changed:
dstext.f calling sequence changed:
This affects routines in:
gempak/gpmap.c
gempak/pthgt.f
gempak/ptitle.c
gempak/pvprof.f


Gempak 5.4.3 allows color coding of parameters by value (eg a surface plot
of temperature can have color values assigned to a data range). This
changees the COLORS calls in the sfmap routines:
gempak/psurf.f --> sfmprm calling sequence changed
SFMPLT
SFMCOF
SF_SNXTA

gempak/pupa.f
SNMCOF delete imark from call
SNMPLT delete imark from call 


inline.f sequence change:
gempak/wprofbor.f
gempak/psgrid.f
gempak/pstream.f
gempak/pxsec.f
