errno.h on FreeBSD contains ENOATTR instead of ENODATA

Added missing function parameter "value"

Allow UTF8 in tests/run/annotate_html.pyx

Otherwise tests are failing on my box with a UnicodeDecodeError.

So allow for that value in this enumeration.
Added immediately after ENODATA

This reverts commit e4fcfa3b.

This is a workaround for github hissue #1530.

Closes github issue #1533.

This helps with #1510. There is still a bug in that the builtin
classmethod is not use here.

This fixes #551.

A header was added to the html file, now check the first 100 chars.

This fixes #1519.

Only analyse typeless inner expressions.

Cython uses many static inline utility functions.  Most compilers
don't emit warnings for such functions, but Clang does if they're
not defined in header files.  As such functions are often defined
as a group (e.g. utility code for a specific type) it would be
cumbersome to thin them out to those that happen to actually get
used.  Instead, simply suppress this warning for this compiler
for all inline functions.

This fixes #1523.

This closes #1522.

Move CYTHON_UNUSED macro up such that included files can use it

Closes #1506

Closes #1506

Fixes #1499
