This patch introduces the following changes:
1) introduces new flag VMA_AREA_SYSVIPC to mark corresponding vma entries.
2) enhance task /proc/<pid>/maps parsing to obtain first 5 letters of mapped
file. If device major file belong to ins equal to 0 (tmpfs) and it's name
starts with "/SYSV", then this mapping is considered as SYSV IPC and
corresponding vma entry status is updated with VMA_AREA_SYSVIPC flag.
3) omit dumping of mapping pages for SYSV IPC vmas.
