Log message size limitation

[si14]

We should take in account fact that user can try to log a very large data (big lists and binaries, for example). We should trim such messages (this trimming should be enabled by default and one should have an ability to disable it). Also http://erlang.org/pipermail/erlang-questions/2011-July/060102.html

I think we should do it only for our logs. I mean alog_tty, alog_disk_log, alog_syslog and scribe log.
When user implements his own logger, he should care about described problem. Alogger only sends data to loggers and we should not decide for a user what must be logged.
