4.2.0-rc

Changes since v4.2.0-beta:

• Fixed performance regressions.
• Made further memory usage improvements.
• Fixed build issues with clean target and runtime_library_dirs.
• Revised package structure to make policyrep a module of the setools package.
• Symbol names are now available as the name attribute (e.g. Boolean.name, Type.name, etc.)
• Fixed some apol layouts to increase the size of text fields.
• Move constraint expression to its own class.
• Made Conditional.evaluate() more useful and added BaseTERule.enabled() method to determine if a rule is enabled..

Changes since v4.1.1:

• Replaced the Python/SWIG/static-linked-libsepol policyrep module with a Cython implementation. This will have performance and memory-usage improvements and breaks the static linking to libsepol.
• Significant memory usage reduction in sediff (approximately 60%, depending on the policies).
• Added support for SCTP portcons
• Updated permission maps
• Support for Python 2.7 was dropped

This release of SETools has changed dependencies since 4.1.1. See README.md for more details.
