NAME
	clear_bit - clear a bit in a bitstring

SYNOPSIS
	string clear_bit(string str, int b)


DESCRIPTION
	Clear the bit b in bitstring str and returns the new bitstring.
	The length of the bitstring will dynamically increase if
	nescessary.

	Config.h must define MUDOS_BITSTRING for bitstring functions to
	exist.

ERROR
        If b < 0 an error will occur. The resulting bitstring must also be
        smaller than MAX_STRING_SIZE.

NOTE
	Bitstrings are currently on byte level. This may change in the
	future, so do NOT make ANY assumptions on bitstring data.
