Felix Geisendörfer c93e0aaf06 Deprecate string interface for fs.read()
This patch makes buffers the preferred output for fs.read() and
fs.readSync(). The old string interface is still supported by
converting buffers to strings dynamically. This allows to remove the
C++ code for string handling which is also part of this patch.
