the ability to have strings up to 32k characters. This implies that using
setinputsizes() is necessary if a long string type is desired as this will not
occur automatically when the string exceeds 4000 characters. Tests are tidied
up to remove the "p_" prefix from all bind variables.
deprecating allocelems (replaced by numElements) and maxlength (replaced by
bufferSize); avoid increasing memory allocation for strings when using variable
width character sets and increasing the number of elements in a variable during
executemany(). Thanks to Don Reid for pointing out this issue.
