Summary:
Fix read/write in binary format, which crashes Python 3.
Additionally, clean up redundant (as for Python 3) code and
fix a handful of flake8 warnings.

In Python3, dict.items, dict.keys, dict.values, zip, map and filter no longer return lists, they create generator instead.
The portability patch consists in forcing an extra `list` call if the result is actually used as a list.
`map` are replaced by list comprehension and `filter` by filtered list comprehension.

In Python2, division between integer yields an integer, while it yields a float in Python3.
Use a combination of from __future__ import division and // operator to get a portable behavior.

Using from __future__ import print_function it is possible to have a compatible behavior of `print(...)` across Python version.

Have all classes derive from object: that's implicitly the default in Python3,
it needs to be done explicilty in Python2.

Combined with enabled flag for stable filenames, this greatly simplifies
finding the offending report.

Indeed, "CHANGE" is not a thing yet, and we should probably not carry
around dead code which does not do anything apart from confusing the
reader.

- Exporting needed function for future reuse.
- Idiomatic python: using with `file as f` instead of `try/finally`.
- Fixing some indentation issues.
- No need to reinvent python `multiprocessing.getCPUCount()`
- Removing a function parameter which is always the same under all invocations.
- Adding some docstrings.

This patch adds hashes to the plist and html output to be able to identfy bugs
for suppressing false positives or diff results against a baseline. This hash
aims to be resilient for code evolution and is usable to identify bugs in two
different snapshots of the same software. One missing piece however is a
permanent unique identifier of the checker that produces the warning. Once that
issue is resolved, the hashes generated are going to change. Until that point
this feature is marked experimental, but it is suitable for early adoption.

This allows us to compare two direct invocations of the analyzer on a
single source file without having to wrap the output plists in their
own directories.

This prevents us from treating the issues from different files with the
same function names and same offsets as the same.
The issue identifier now includes the file name. Also added a way to
strip off the root directories form the source file names.

CmpRuns can be used for static analyzer bug report comparison. However,
we want to make sure external users do not rely on the way bugs are
represented (plist files). Make sure that we have a user
friendly/documented API for CmpRuns script.
