19991202: Thoughts on Nmap and number of files in a directory

I have run into problems with nmap where I exceed the maximum
number of files in the data directory.

FL_MFIL has the maximum number of files(300) hardcoded.
Also, FL_SCND called by FL_MFIL is hardcoded with
the size of the filnam string (12801) in 2 places.
These sizes might be good candidates for the gemprm.prm
file.

More importantly, there is currently no error check in
those routines which prevents a messy crash when
CFL_SCND returns more than 300 file names in the string.
If the sizes were defined in the include files, then
FL_SCND would only need to check if nf > maxfilenames
and create an error message, or truncate the list
as appropriate.
