This avoids possible buffer overreads when int(), float(), compile(), exec()
and eval() are passed bytes-like objects. Similar code is removed from the
complex() constructor, where it was not reachable.

Patch by John Leitch, Serhiy Storchaka and Martin Panter.

The mkstemp() and mkdtemp() signatures have already been updated, but the
higher-level functions still suggest that the default values are forced to
text strings. Also merged some paragraphs describing the "suffix" and
"prefix" parameters, and pointed out that mktemp() does not support the new
changes.
