Patch #1731049: make threading.py use a proper "raise" when checking internal state, rather than assert statements (which get stripped out by -O).

support the complete capability of HCI on FreeBSD yet.

Closes bug #1730389.  Will be backported.

Different versions of Berkeley DB handle this differently.
The comments and bug report should have the details.  Memory is allocated
in 4.4 (and presumably earlier), but not in 4.5.  Thus
4.5 has the free error, but not earlier versions.

Mostly update comments, plus make the free conditional.

This needs to be backported.  I'm too tired tonight.  It would be great

specify an error handling scheme for character conversion. Additional
scheme "utf-8" in read mode. Unicode input filenames are now

Fixed: In read mode use a possible pax header size field.
Fixed: Strip trailing slashes from pax header name values.
Fixed: Give values in user-specified pax_headers precedence when
writing.

Added unicode tests. Added pax/regtype4 member to testtar.tar all
possible number fields in a pax header.

Added two chapters to the documentation about the different formats
tarfile.py supports and how unicode issues are handled.
