This change is a pure refactoring of the common bits of minidump_writer.cc that will be shared soon with the upcoming microdump_writer.cc. In particular, this CL is extracting the following classes: - ThreadInfo: handles the state of the threads in the crashing process. - RawContextCPU: typedef for arch-specific CPU context structure. - UContextReader: Fills out a dump RawContextCPU structure from the ucontext struct provided by the kernel (arch-dependent). - SeccompUnwinder: cleans out the stack frames of the Seccomp sandbox on the supported architectures. - MappingInfo: handles information about mappings BUG=chromium:410294 R=mmandlis@chromium.org Review URL: https://breakpad.appspot.com/4684002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1388 4c0a9323-5329-0410-9bdc-e9ce6186880e
