Correct wrong frequency array index in fxdecon.f90 (bug #156). Also apply
same patch to fxdnoise.f90, fxinterp.f90 and fxtis.f90, as they reused the
code from fxdecon.f90.
Add count of number of windows denoised to fxdnoise.90.
Add count of traces killed due to amplitude out of range in scab.f90.

Add option to process HEADMAP to reduce printout.

Fix problem in spsrps.f90 where values stored as 8-bit or 16-bit could
receive an INIL due to field being blank in SPS files, and truncated to
invalid result (INIL is -888728). So convert INIL to zero to avoid this.

Update comments in xps.f90 and spsrps.f90

Fix tapeio.c to compile in Fedora 40. Thanks to Tahir Helvaci for spotting
this bug.
Update comments in vc.f90

Patch for pcard.c from Tahir Helvaci, who found it would not compile in Fedora 40.
Add autocorrelation option to VC process, to provide a Klauder wavelet from sweep.

Changed TTRIN and TTROT to operate with local tape drive. The existing
processes were written for remote drives with operators and tape library.
They were not usable without additional software. Also found they only
worked in 32-bit linux, due to some variables declared as long integer.
Fixed that and it now works in 64-bit linux.

Revise the cfe_apphelp.xml file as it just said "This is the application help".
Unfortnately, that popup is unformatted like the others, so without word wrap
it is limited to one line of about 100 characters.
Update comments in the f90 files.

Fix issues in avovit.f90 and update comments in other files.

Add input trace check to avocorr.f90, as missing traces could cause malloc
memory corruption errors, which are not user friendly. Also add the gather
check and LAV setting, which was common issue with the AVO processes.
