Weave incorrectly assumes PyStrings are NUL-terminated (Trac #657)

[scipy-gitbot]

Original ticket http://projects.scipy.org/scipy/ticket/657 on 2008-04-26 by trac user jonny5532, assigned to unknown.

Weave incorrectly assumes that PyStrings are NUL terminated - they infact store the length separately. As a result, all conversions to/from std::strings can be unnecessarily truncated if they contain NUL characters as they go via char* arrays.

I have fixed this locally by changing the code surrounding PyString_FromString and PyString_AsString calls which convert to/from std::strings to also note the length of the string.

Closing since weave is no longer a part of SciPy. This issue is now tracked at scipy/weave#7.
