revert to using codecs.open() for output files instead of io.open() as the latter cannot write str objects in text mode under Py2 (and we erroneously do that in some spots)

make encoding detection code a bit faster if the first two source file lines are longer than 250 bytes

Get rid of obsolete Python cruft.

cython-mode.el: don't highlight builtins when they're part of varname

simplify test for GCC >= 2.95 for branch prediction

document memoryview attributes better

revert to using malloc/free for data buffer allocation in case external code wants to fiddle with it

make it easier for the C compiler to prune some useless error checking code in cython.array constructor
