netwib

This release adds netwib__debug_ctrlc_pressed_break() to find memory leaks in debug mode. It limits the number of recursive directories that can be created to 100.

The licence was changed from GPLv2 to GPLv3. gcc 4.3 warnings about unused functions are suppressed.

A memory leak in netwib_dir_init() was fixed. Some netwib_buf functions were renamed. A new flag was created to wipe memory of sensitive buffers. A bash shell with a TTY and readline can be set in a netwib_io. The netwib_hash_ctl_get_count() function was created.

Support for Tru64 Unix was added. During
compilation of the libnetwib.so dynamic library,
GCCLIB was missing.

The uint64 module was rewritten to have common
defines supporting 64 and 32 bit processors.
