We use global variable TSC_FREQ defined in config.py in each of the analyzers.
And the value set to TSC_FREQ through option -f/--frequency doesn't take effect.
This patch fix it by adding one parameter to each of the analyzers and pass
the value set by -f/--frequency to it instead of use the global one.

This patch adds the steps required to use the newly
introduced blkrescan feature for Virtio-blk device.
Tracked-On: #3051
Signed-off-by: Vijay Dhanraj <vijay.dhanraj@intel.com>
This patch adds support for new acrnctl command blkrescan.
Purpose: To add a virtio-blk device to guest VM after launch.
Use case:
1. Anticipate number of block devices that will be needed
and add empty backend file while launching VM.
e.g: -s 5, virtio-blk,nodisk
2. Use the following acrnctl command to trigger
a rescan of virtio-blk device by guest VM, to
revalidate and update the backend file.
“acrnctl blkrescan VMname slot,newfilepath”
v5 -> v6:
- Removed unsed #define
- Reduced the size of param len of blkrescan command
from 512 to 256.
v2 -> v5:
- No change
v1 -> v2:
- Renamed the acrnctl command and APIs from diskplug
to blkrescan.
- Split the patch into two. This corresponds to
changes in tools.

This patch refines the process of log space check.
Check a folder's size need to traverse all nodes of files and subdirs,
in the case of extreme memory strain, accessing these log file nodes
frequently will increase the IO pressure on the eMMC.
Previously, all log files will be accessed and counted in each space
