Runtime/testcase/tstRTSystemQueryOsInfo: added output of RTSystemQueryTotalRam() and RTSystemQueryAvailableRam()
header (C) fixes
*: Replaced memchr(psz, '\0', cb) with RTStrEnd(psz, cb) and worked around memchr(,, RTSTR_MAX) issue in RTStrEnd. Here (linux.amd64 / glibc-2.10.1-r1) memchr fails for cb > ~(size_t)11. Since RTSTR_MAX is ~(size_t)0, this behavior breaks several IPRT string APIs.
Automated rebranding to Oracle copyright/license strings via filemuncher
tstRTSystemQueryOsInfo.cpp: Copied back the corrected overflow test from tstRTSystemQueryDmi.cpp.
