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...

Replace my original asprintf() and vasprintf() hacks with something

more cleanly integrated with stdio. This should be faster and cleaner since it doesn't memcpy() the data into a seperate buffer. This lets stdio allocate and manage the buffer and then hand it over to the user. Obtained from: Todd Miller via OpenBSD

Added #include to get prototypes.

Rework previous commit.. I was confused by the number of diffs in the PR

and forgot what I was trying to do originally and accidently zapped a feature. :-] The problem is that we are converting a counted buffer in a malloc pool into a null terminated C-style string. I was calling realloc originally to shrink the buffer to the desired size. If realloc failed, we still returned the valid buffer - the only thing wrong was it was a tad too large. The previous commit disabled this. This commit now handles the three cases.. 1: the buffer is exactly right for the null byte to terminate the string (we don't call realloc). 2: it's got h.left = 0, so we must expand it to make room. If realloc fails here, it's fatal. 3: if there's too much room, we realloc to shrink it - a failed realloc is not fatal, we use the original buffer which is still valid.

Fix off-by-one error

This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

Fix some of the problems that bde pointed out to me some time ago.

- buffer expansions were not working right due to a return code botch. - signed types instead of size_t's meant somebody else went and put casts in, I've changed the types to what they should have been.
