Current implementation save trace data files on tmpfs by default, acrntrace

This commit changes default location for trace data file to current dir, and
removes the codes for space reservation, which is not necessary.

in the $PATH on the Service OS. This creates an obscure dependency. The patch
changes the code to use standard C APIs to perform the same functionality which
makes the code more self-contained.

acrntrace writes trace data to /tmp with unlimited size and will cause tmpfs
100% occupied. Consequently, some problem will raise up on SOS, like failing to
exec cmd.
This patch introduce an option -r to let user configre minimal space left on the
disk which ensures that acrntrace will exit when free storage space is less than
the reserved space. By default, we reserve 512M on the disk. Users can configure
reserved space through '-r'.

The trend is to focus on Python3 and deprecate Python2. This patch make all the
acrntrace related scripts as Python3 module.
- Add parentheses to all the print as Python3 required.
- Remove suffix L and long() Python3 has deprecated. Python3 will treat all
intergers as long.
- Replace has_key() with "key in .keys()" because has_key() has been deprecated.

Benefits of outputing trace data as raw data:
- Smaller trace data size
- More convenient to add new trace entry. There is no need to change acrntrace
when we add new trace entry to HV. All we need do is to update the analysis
scripts to deal with this situation.

~57M -- with patch
~137M -- without patch
