MacroExpand leaks in, in->args, in->args[] for various failure cases

[GoogleCodeExporter]

What steps will reproduce the problem?
1. run Coverity on mozilla-central from something after 
http://hg.mozilla.org/mozilla-central/rev/582be9aca672

What is the expected output?
no memory leak warnings in MacroExpand

What do you see instead?
warnings that "in" is leaked

What version of the product are you using?
r367

On what operating system?
Linux with Coverity 4.5

Please provide any additional information below.
The patch here tries to handle two distinct cases:
* early failure by arg scanning (before in-> is filled)
* later failure after in->args[] is filled (in two similar blocks, by 
refactoring)

Note that the I'm not adding code to handle failure to allocate in->args from 
malloc(). The code also seems to have a random mix of tabs and spaces. I tried 
to follow style or at least not rewrite the file.

The old preprocessor has been replaced with a completely rewritten one.  This 
issue should no longer be a problem.
