[bananas] Patches to 31DEC09

[Eric Greisen]

A couple of insidious errors were found:

1. DBCON could overwrite the input file headers with a header that is no 
longer correct for that file (frequency changed to ref pixel 1) when the 
AN file needed reformatting.  That could occur on an unknown array. 
Corrected the reformatting to be more careful and added stations and an 
array to the known lists.

2. Copying of bandpass tables omitted any record for which one or both 
polarizations had failed solutions.  This lost good solutions and even 
when both failed caused the application of BP tables to be different 
after a copy.

The COMLNK is so long on these two combined that a script is available 
for those sites that need to apply the patch by hand.  Go to
          http://www.aips.nrao.edu/31DEC09/patches.html
for information on all 15 patches to 31DEC09.

Binary installations should simply run a MNJ.
