Add bitarray functions for setting and clearing all the array

Browse source 
- bitArraySetAll() and bitArrayClrAll() set and clear the whole
array, with the size (in bytes) specified by the caller (to make
them work like bitArrayFindFirstSet())
- macros BITARRAY_SET_ALL() and BITARRAY_CLR_ALL() call those two
new functions using sizeof(array) as its size
