Do not line buffer code generator output
Line buffering results in slow performance on FUSE- and network-based
file systems, e.g., eCryptfs. std::ostream << std::endl emits a
newline and flushes buffers to the kernel[1], yielding excessive
system calls. Instead, emit "\n" which does the equivalent without
the flush[2]. The attached patch accomplishes this while minimizing
code churn by removing "using namespace std" and introducing a static
variable endl.
