Fix HDFFV-11120 and HDFFV-11121 (CVE-2018-13870 and CVE-2018-13869)
Description:
When a buffer overflow occurred because a name length was corrupted
and became very large, h5dump produced a segfault on one file and a
memcpy parameter overlap on another file. This commit added checks
that detect a read pass the end of the buffer to prevent these error
conditions.
Platforms tested:
Linux/64 (jelly)
