Bug 323471: Remove nsTString::ToCString
Attachment 208522: patch
------- Additional Comments from Brian Ryner
In order to cover some of the use cases for ToCString, I added versions of
Lossy[Convert|Append]UTF16toASCII that write into a raw char buffer. The
caller must pass in the length of the buffer, and the method fails if the
buffer turns out not to be large enough.
