Add utility methods to Crash Parser

Also update the filtering implementation to be cleaner and easier to read.

* add process name to Crash.java
* detect crashes on process regex instead of thread name
* add the crash blob string to Crash.java
* add matchSecurityCrashes() to CrashUtils.java
* use BigInteger instead of long to correctly compare 64-bit addresses
* update unit tests
