Code and documentation improvements for all abstract domains

Insert missing return statements into the control flow graph.

Added a simple check that prints an error message when no dynamic symbol calls could be resolved.

Added brand new (and still experimental) checks for CWEs 415 and 416 together with a new interprocedural data-flow analysis engine written in Rust. Add `-partial=Memory` as command line flag to try out the new checks.

Each unit test can now be run with a separate test binary, making all unit tests more flexible.

Change the address translation function so that we are able to report more precise incident locations.

Added a new symbol structure enabling more precise handling of extern symbols.

Add "--version" to command line options.

Update emulation based acceptance tests on the basis of the new deduplicated warning output

Improved the CWE reports generated by emulation based checks.

Upgraded the BAP version to its current development version.

Unit tests no longer fail silently on Travis CI builds.

refactored cwe476 to add stack tracking

Added acceptance tests for more CPU-architectures. Added acceptance tests for PE-files for x86.

prepare v0.3 release

Added cwe_checker executable allowing shorter command line calls

This PR fixes two minor bugs and adds a workaround for the address computation of Ghidra, which sometimes adds an offset and sometimes not. There seems to be no function in the Ghidra API that can be used to tell the plugin when this happens and when not.

This PR adds a plugin for annotating the results of the cwe_checker in Ghidra.

adds check_path flag to cwe_checker for finding paths from user input functions to CWE hits.

This also fixes a bug in nested_exp_list, causing Load instructions to be added twice instead of once.
