cfgfile: fix parsing of long fields

When parsing a ini file with a "key = value" line that has both "key" and
"value" sized to the maximum allowed length causes a parsing failure.  The
internal "buffer" variable should be sized at least as large as the maximum
for both fields.  This commit updates the local array to be sized to hold
the max name, max value, " = ", and the nul terminator.
