stress-ng V0.18.01 "synchronized synthetic stressor"

New stressors:

• --min-nanosleep to measure minimum time nanosleep will sleep

New options:

• --sync-start to synchronize the start of stressing with invoked stressor instances
• --mmapfork-bytes to specify mmap size
• --yield-sched to specify scheduler type (deadline | idle | fifo | other | batch | rr)
• --pci-dev option to specify a specific PCI device to exercise

Detailed changelog:
