SERVER-14538 _appendUserInfo: don't save addr pointing to temporary

Before de724781, the return value of CurOp::getNS() had a lifetime of
the CurOp object.   As of de724781, CurOp::getNS() returns a
temporary.

_appendUserInfo() initialized a StringData from the result of
CurOp::getNS(), which was poor style but technically valid before
de724781.  As of de724781, the buffer being pointed to by the
StringData is destroyed along with the temporary, creating a
use-after-free at introspect.cpp:70 when the StringData is read.

SERVER-14284 cursor6.js, update_setOnInsert.js turn profiler off

SERVER-12751 remove BSONBuilderBase
SERVER-9570 SERVER-9572 Default install prefix to subdirectory of selectable build dir

In addition, move the .scons directory to a subdirectory of the build
directory. This makes all build artifacts not installed to '#' live under the
build directory.
SERVER-14343 Build fast and loose by default
SERVER-11290 Don't actually build static libraries

We don't currently use the static libraries, they are just nodes in our
dependency graph. Since they are unused, building them wastes time and disk
IO.

We still need to generate the files to appease scons. They are filled with a
UUID on the assumption that if scons thinks that a library needs to be rebuilt
then anything that depends on the library should also be rebuilt.
