• fix clang++ compilation error
• fix patricia glue node prefix
• fix compilation error for building libbgpstream with sqlite support

• remove redundant unreachable breaks
• clean up bgpreader exit
• remove redundant log messages
• fix invalid enum value
• clean up some integer conversion safety
• separate package and shared library versions

Testing

• fix compiler warnings that break auto build test
• clean up unused functions and variables in test
• add more IP address mask tests
• fix/improve patricia test
• modify tests to not quit after first FAIL
• fix compiler warning in test suite
• add AS path unit tests
• add exit status to work with automake script-based tests
• add unit tests for snprintf-like functions

libparsebgp

• fix unused variable in STATIC_ASSERT
• fix compiler warning that breaks auto build test
