 *  Bugs:
 *    Commented out warnings of type mis-matches in check_and_copy_key
 *    There is evidently a bug in append_keyval_to_primekeyval() in keystuff.c,
 *      as the ingest_track module was generating a seg fault in
 *      drms_setkey_string() with values of the PrimeKeyString like
 *  1987:000.0|22.5|-52.5|2002.03.30_00:44:30_TAI|1664|16.0|16.0|0.100000|0.000000|Postels|0.12500|0.00000|prog:mdi,level:lev1.5,series:fd_V_01h[80986-81014],sel:[53-36]
 *      I was only able to work around this by changing the initial value of
 *      buflen in append_keyval_to_primekeyval() from 128 to 256
 *    Many combinations of legitimate prefixes and unit strings for WCS time
 *      descriptions are not yet supported
 *    Consistency of floating-point key values in check_and_setkey_XXX is
 *      only guaranteed to within the recommended format precision; this is
 *      by design
 *    check_and_setkey unimplemented for keys of type char and long long
 *

/*
 *  Revision History (all mods by Rick Bogart unless otherwise noted)
 *
 *  09.04.27 or earlier created file
 *  09.05.16            added functions for creating prime key string
 *  09.11.06            added WCS parsing function
 *  09.11.09            modified check_and_set_key_* to only require matching
 *              to precision of keyword format for float, double, & time
 *  09.12.02            fixed two icc11 compiler warnings and one error
 *  10.01.07            added support in check_and_copy_key for keywords that
 *              are dynamic links (in which case checking is irrelevant)
 *  10.02.03            relaxed check in check_and_copy_key (too much)
 *  10.04.24            added copy_prime_keys()
 *  10.06.11            added construct_stringlist() (orig in drms_rebin)
 *  12.03.21            added check_and_set_key_longlong()
