SERVER-13923 BtreeLogic unit-tests
SERVER-13637: remove some header files leaking
SERVER-12461 Use larger values to test for too large $position arguments.

The previous values were integers that were just 3 away from the largest
possible 64-bit integer, were parsed as the same float as the largest possible
integer, and so were accepted.  This changes them to be much much larger.

SERVER-13463: Option Validation for NT Services

The current working directory for NT Services differs between installation time
and execution time. This leads to subtle user bugs where the service can fail to
start because directories do not exist. In the worst situation, the log file
directory may not exist which makes the debugging near impossible.
