Better document how sensitive variables can be indicated via command line arguments, especially the fact that structs can be also specified.

Renamed the new arguments to be more consistent with previous argument names (cpp-command instead of cpp_command and similar for the others) and made the functionality work correctly.

Added preliminary support for compilation database use + cpp_command and cpp_extra_args options (à la frama-c). Needs more testing but should at least not introduce any regressions

Corrected definition for HMAC_Final. Before, the output of a hash function would not depend on the input...

Implemented call graph generation. It uses the same code as the dependency analysis and is thus slow, but it's better than nothing.

Corrected issue where the definition of functions references by global function pointers could not be found.

Changes function priority: when multiple definitions for the same function are encountered, the first one is kept. This allows to specify the variants one wishes to be considered as command line arguments of the script.

Corrected the handling of dependencies of the form struct -> non-struct (i.e. memcpy secret values into a char * casted struct)

Indirection of array-types corrected: array and &array are now (supposed to be) equivalent (fixes #8)
