2011-03-25	Merge in ports work	Peter Seebach
	This is a spiffied-up rebase of a bunch of intermediate changes, presented as a whole because it is, surprisingly, less confusing that way. The basic idea is to separate the guts code into categories ranging from generic stuff that can be the same everywhere and specific variants. The big scary one is the Darwin support, which actually seems to run okay on 64-bit OS X 10.6. (No other variants were tested.) The other example given is support for the old clone() syscall on RHEL 4, which affects some wrlinux use cases. There's a few minor cleanup bits here, such as a function with inconsistent calling conventions, but nothing really exciting.
2011-02-08	Expand paths on exec.	Peter Seebach
	This is fussy, because we have to actually do the path search ourselves as best we can to handle unqualified paths. The result, though, is more meaningful logs. Along the way, fix some bitrot in the comments in pseudo_fix_path and friends.
2010-12-13	Further amend the system to enable/disable sudo during fork/exec.	Mark Hatle
	2010-12-09: * (mhatle) Add doc/program_flow to attempt to explain startup/running * (mhatle) guts/* minor cleanup * (mhatle) Reorganize into a new constructor for libpseudo ONLY pseudo main() now manually calls the util init new / revised init for client, wrappers and utils * (mhatle) Add central "reinit" function * (mhatle) Add manul execv* functions * (mhatle) rename pseudo_populate_wrappers to pseudo_check_wrappers Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2010-09-16	The exec*() functions were inconsistent about the name of their first	Peter Seebach
	argument -- which turns out to be a problem, as this controls the canonicalization. The upshot is that some invocations of symlinks were corrupting $0.
2010-08-25	Initial attempt at fixing problems with SIGCHLD being blocked	seebs
	in processes started under pseudo.
2010-08-11	Enable local variable cache	Mark Hatle
	Add local variable cache via get_value and set_value. The local cache is setup at constructor time (or soon after). Rewrite the pseudo_setupenv and pseudo_dropenv routines, add a new pseudo_setupenvp and pseudo_dropenvp as well to handle the execve cases. We can now successfully use /usr/bin/env -i env and get pseudo values back!
2010-08-11	Enable execl, execle, execlp, execv, and execvp wrappers	Mark Hatle
	We wrap all of the execs so that we can ensure the environment is properly configured prior to the exec running. handle ... for the new execl* wrappers Add a test for the new execl* ... handling.
