// Writes a microdump (a reduced dump containing only the state of the crashing
// thread) on the console (logcat on Android). These functions do not malloc nor
// use libc functions which may. Thus, it can be used in contexts where the
// state of the heap may be corrupt.
// Args:
//   crashing_process: the pid of the crashing process. This must be trusted.
//   blob: a blob of data from the crashing process. See exception_handler.h
//   blob_size: the length of |blob| in bytes.
//   mappings: a list of additional mappings provided by the application.
//
// Returns true iff successful.
