* semantic.el (semantic-error-if-unparsed): New function. Raise
error if buffer was not parsed by Semantic (bug #12045).
(navigate-menu, edit-menu, cedet-menu-map): Enable Semantic items
only if buffer was parsed. Also, replace ':active' with ':enable'
where necessary.
* semantic/wisent/python.el
(semantic-python-get-system-include-path): Use
`python-shell-internal-send-string' if available to query Python
for system paths.
* semantic/senator.el (senator-next-tag):
(senator-previous-tag):
(senator-go-to-up-reference): Use `semantic-error-if-unparsed'.
* semantic/complete.el (semantic-complete-jump-local):
(semantic-complete-jump):
(semantic-complete-jump-local-members):
(semantic-complete-self-insert): Use `semantic-error-if-unparsed'.
(semantic-complete-inline-project): Fix autoload cookie.
* semantic/analyze/complete.el
(semantic-analyze-possible-completions): Check if buffer was
parsed. Only raise an error if function was called interactively,
otherwise silently return nil.
* cedet.el (cedet-menu-map): Fix copy&paste typo in menu creation.
(semantic-ctxt-current-assignment): New overrides, simply returning
nil. The defaults do not work correctly and can send the parser in
an inifinite loop (bug#12458).
