We log a number of messages during startup, whether or not logging is enabled. However, logcat messages take non-trivial (and not entirely predictable) amount of time to process, so we should limit their number by default in order to speed up startup. Tests show the following improvements resulting from this change: * Displayed: 1.49% faster * Native-to-managed transition: 7.47% faster * Total native init time: 5.94% faster

[^0]: Numbers from running [XAPerfTestRunner][0] with **all** of
logcat logging disabled, including `monodroid-timing` messages.
The `timing=fast-bare` mode is used, which doesn't log anything
until asked to do so.
This way logcat's inherently unpredictable behavior was
completely removed and the results are more stable.
