2010-12-07	This is a merge of several commits from a tree which turned out to	Peter Seebach
	be out of sync in a very inconvenient way. Changes include: * Some whitespace fixes, also move the pseudo_variables definition into pseudo_util.c since it's not used anywhere else. * Further improvements in the fork() support: We now recognize both positive and negative forms of PSEUDO_DISABLED, so we can distinguish between "it was removed from the environment by env -i" (restore the old value) and "it was intentionally turned off" (the new value wins). * clone(2) support. This is a little primitive, and programs might still fail horribly due to clone's semantics, but at least it's there and passes easy test cases. Plus a big patch from Mark Hatle: Cleanup fork/clone and PSEUDO_DISABLED guts/fork.c: * cleanup function and make it more robust * be sure to call pseudo_setupenv prior to pseudo_client_reset to match exec behavior pseudo_wrappers.c: * fix mismatched type in execl_to_v call via typecast * Simplify fork call via single call to wrap_fork() * be sure to save pseudo_disabled * be sure to call pseudo_setupenv prior to pseudo_client_reset to match exec behavior tests: * Add a test of whether pseudo can be disabled/enabled on a fork.

2010-10-25	Clean up makewrappers a bit.	Peter Seebach

2010-10-11	Major change: Replace the shell-based makewrappers with a Python	Peter Seebach
	one. There's a long story here, but to abbreviate it: The shell script was annoying at best to maintain and starting to show signs of not really being the right tool for the job. For various reasons, we have some other Python stuff in our build system, so we picked Python as the language we were already using for other stuff. We think this works with anything reasonably recent (around Python 2.4 through 2.6). There's a little bit of cleanup, also, of the wrapper templates.
