Only realloc() environ if we're sure that we know where it came from.

2000-09-20T03:05:37Z

The recent problems with sshd were due to sshd reassigning `environ' when setenv() thinks it owns it. setenv() subsequently realloc()s the new version of environ and *boom*

o Back out rev 1.4 - reallocf() failure clobbers existing `environ'.

o Do not override `environ' if realloc() fails, leave it intact. o Set `alloced' only when memory is actually allocated. PR: bin/5604 (2nd part) Reviewed by: bde

Replace memory leaking instances of realloc with non-leaking reallocf.

In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

General -Wall warning cleanup, part I.
