[Crash-utility] Source code formatting cleanups

Hi, Dave Reading through the 'crash' source code I found that it uses different styles across codebase. I went ahead and fixed the most common formatting problems. The changes can be found here https://github.com/anatol/crash Here is the list of cleanups. Most of them are self descriptive: 21da621 Indent the code using GNU indent tool 8b9c671 Replace leading spaces with tabs 9ce66d8 Remove trailing whitespaces f67b4c3 Fix misspellings using codespell tool 92fc952 Convert Windows EOL to Unix one using 'dos2unix' tool Feel free to pick any of them. Actually most of the changes (except the codespell one) are fully automatic and can be rerun on your local machine. And "Replace leading spaces with tabs" is not strictly needed as "indent" change will do the same, I just kept them separate if you want to pick only one of the changes.
