Bug fix release, address shared memory unmapping for opcode, sysbadaddr, enosys and sysinval stressors. Fix trimming in malloc stressor, fixes memory leak in mmap stressor.

[Colin Ian King]

• Makefile: bump version
• Makefile: remove -g from CFLAGS
• stress-sock: fix memory real on mmap_buffer
• stress-malloc: replace pre-inc with post-inc on trim_counter
• stress-tsc: only define stress_tsc_check when required
• manual: update release date
• stress-opcode: allow exit system call
• stress-sysbadaddr: don't unmap shared memory, just make it read-only
• stress-enosys: don't unmap shared memory, just make it read-only
• stress-opcode: don't unmap shared memory, just make it read-only
• stress-sysinval: don't unmap shared memory, just make it read-only
• stress-tsc: clean up warnings with systems that do not support lfence
• stress-sysonval: add in missing old/deprecated and new system calls
• stress-enosys: add in missing _NR* syscalls
• README.md: add another kernel issue found by stress-ng
• stress-malloc: mmap addr array and prefetch values
• stress-malloc: only trim memory when new option --malloc-trim is used
• stress-tsc: add the --tsc-rdtscp option
• Add build-time check for rdtsc instruction
