Anna Zaks 7920eb0b1f Reapply: [asan] On OS X, log reports to syslog and os_trace 
When ASan currently detects a bug, by default it will only print out the text
        of the report to stderr. This patch changes this behavior and writes the full
        text of the report to syslog before we terminate the process. It also calls
        os_trace (Activity Tracing available on OS X and iOS) with a message saying
        that the report is available in syslog. This is useful, because this message
        will be shown in the crash log.

        For this to work, the patch makes sure we store the full report into
        error_message_buffer unconditionally, and it also strips out ANSI escape
        sequences from the report (they are used when producing colored reports).

        I've initially tried to log to syslog during printing, which is done on Android
        right now. The advantage is that if we crash during error reporting or the
        produced error does not go through ScopedInErrorReport, we would still get a
        (partial) message in the syslog. However, that solution is very problematic on
        OS X. One issue is that the logging routine uses GCD, which may spawn a new
        thread on its behalf. In many cases, the reporting logic locks threadRegistry,
        which leads to deadlocks.

        (In addition, add sanitizer_common_libcdep.cc to buildgo.sh to avoid
         build failures on Linux.)
