Fixes GH-235

This reverts commit 585af938.

When adding a large amount of data that spans to multiple chunks, the pointer is incremented by the wrong value.

From autoconf manual, section 5.6.1 Portability of Headers, says:

"""
The C99 standard says that inttypes.h includes stdint.h, so there's no
need to include stdint.h separately in a standard environment. Some
implementations have inttypes.h but not stdint.h (e.g., Solaris 7),
but we don't know of any implementation that has stdint.h but not
inttypes.h.
"""

Remove AC_PROG_RANLIB because it is rendered obsolete by LT_INIT.
Remove AC_CHECK_HEADER_STDBOOl, because travis does not have one.

The assert only evaluates to code if NDEBUG is undefined. Protect rv and its use accordingly
