Assume MOD_POSIX_CURRENCY_SYMBOL contains only ASCII characters
...
The GNU library now has "C.UTF-8" as a locale (which is NOT a single-byte
locale!), but we assume the currency symbol in MOD_POSIX_CURRENCY_SYMBOL
contains only ASCII characters.

Replace "tv.tv_sec * tv.tv_usec" with "tv.tv_sec + tv.tv_usec"

This allows the lower bits of seed to hopefully contain something useful
instead of just zeros!

Correct a subtle off-by-one error in copying in l_strfmon()
...
The bug in l_strfmon() is that bufsize is NOT the length of the string,
hence do not include the usual "+ 1" for the NUL byte. Also correct some
comparisons between signed and unsigned integers.

Compensate for the POSIX locale not having a currency symbol
...
The function l_strfmon() will insert MOD_POSIX_CURRENCY_SYMBOL in the
appropriate place when used with the POSIX ("C") locale.

Revise the scramble() and unscramble() functions

The scramble() and unscramble() functions now use a moving (incrementing)
key for the XOR encryption/decryption. Also include a table of XOR keys
to use at random for encryption.
