- update to 2.49:
* Implement cap_func_launcher() and cap.FuncLauncher().
* More robust "psx" redirection for nocgo compilation - the documentation for
the cgo implementation is now included in the nocgo one because the go.dev
automated documentation builds the docs from the nocgo version.
* Lots of documentation cleanups and added a few man pages: for IAB and
Launching.
* Some general no-op License changes that might cause folk to notice but only
for formatting reasons. These were initially inspired by some lawyerly
interactions, but I ended up rolling back half of them because they
confused automated software infrastructure.
