Some refpolicy interfaces use:
* "$" character in paths, for example in kernel/selinux.if:
genfscon selinuxfs /booleans/$2 gen_context(system_u:object_r:$1,s0)
* empty members in ifelse statement, for example in system/init.if:
ifelse(`$5',`',`',`
...
')
Modify sepolgen/refparser grammar accordingly.
This fixes the following syntax errors reported by sepolgen-ifgen:
/usr/share/selinux/refpolicy/include/kernel/selinux.if: Syntax error
on line 43 gen_context [type=GEN_CONTEXT]
/usr/share/selinux/refpolicy/include/system/init.if: Syntax error on

Since Python 3.3, dictionary hashes are randomized and iterating over
them is no longer deterministic. This makes it difficult to compare
outputs of sepolgen-ifgen command.
Make sepolgen-ifgen deterministic again with Python>=3.3 by always
sorting the dictonaries and sets which are used to produce output.

In Py3.0, the cmp parameter in sort() function was removed and key keyword is
available since Py2.4.

When running sepolgen-ifgen on refpolicy (git master branch), the
following messages show up:
/usr/share/selinux/refpolicy/include/kernel/selinux.if: Syntax error
on line 3369 gen_context [type=GEN_CONTEXT]
/usr/share/selinux/refpolicy/include/system/init.if: Syntax error on
line 188379 ' [type=SQUOTE]
/usr/share/selinux/refpolicy/include/system/init.if: Syntax error on
line 188385 ' [type=SQUOTE]
The line numbers are incorrect because the lineno member of the lexer
object is not resetted after each file has been processed. After fixing
this, the messages are nicer:
/usr/share/selinux/refpolicy/include/kernel/selinux.if: Syntax error
on line 43 gen_context [type=GEN_CONTEXT]
/usr/share/selinux/refpolicy/include/system/init.if: Syntax error on
line 1416 ' [type=SQUOTE]
/usr/share/selinux/refpolicy/include/system/init.if: Syntax error on
line 1422 ' [type=SQUOTE]
As line 43 of kernel/selinux.if contains a genfscon statement with a
gen_context component, the reported line numbers are now correct.

By default in Python3 hash uses random seed as salt, this leads to
different order in output from functions which rely on hash as are
dicts and sets. Tests in sepolgen relied on the frozen order.

Replace usage of print statement with print function.
Use `in` instead of `has_key` when checking for key in dict.
When using `raise` add text (if any) as parameter of exception function.
Add Python3 imports of moved modules.
Replace `map` with list comprehension.
Use reserved word `as` in try-except when catching exception.
Replace `ifilter` function with `filter`.

In Python3 all strings are by default Unicode and both Unicode and String
types are removed from types module. We introduce separate
variables `bytes_type` and `string_type` to reflect Python3 understanding
of strings, on Python2 `bytes_type` refers to <str> and `string_type` to
<unicode>, on Python3 `bytes_type` are <bytes> and `string_type` <str>.
As all strings are Unicodes by default on Python3 we encode them to
bytes when needed as late as possible.
Also other attributes were replaced with their equivalents from
builtins which are available for both Python3 and Python2.

In Python3 the __cmp__ function is removed, and rich
comparison should be used instead.
Also the cmp function is gone in Python3 therefore it is

This fixes the build with "make PYTHON=python2" on systems where python
is python3.
For PYLIBVER and PYTHONLIBDIR definitions, I tested Python 2.5, 2.6, 2.7,
3.3 and 3.4. For each of them, these commands print the expected result:
python -c 'import sys;print("python%d.%d" % sys.version_info[0:2])'"
python -c "from distutils.sysconfig import *;print(get_python_lib(1))"
