- Introduce the following new methods: * `rz_analysis_similarity_basic_block()` * `rz_analysis_similarity_function()` * `rz_analysis_similarity_basic_block_2()` * `rz_analysis_similarity_function_2()` * `rz_analysis_match_basic_blocks()` * `rz_analysis_match_functions()` * `rz_analysis_match_basic_blocks_2()` * `rz_analysis_match_functions_2()` - Remove `RzAnalysisDiff` and its usages - Remove `librz/analysis/diff.c` entirely to and adds `librz/analysis/similarity.c` - Remove a lot of unused structures and simplified the code by a lot - Fix typo in levenshtein - Remove `librz/core/gdiff.c` and `gdiff` functions since they were unused or only used in rz-diff - Remove `difftype` (or "color") from `RzANode` which lead to dead code - Decrease serialized data in projects. - Add `RzAnalysisVarKind` and `RzAnalysisVarType` and replaces all the hardcoded values - Remove command `agd` - Remove all `rz_core_gdiff` usages from `rz_core.h` - Refactor `rz_analysis_var_list` and `rz_analysis_var_count` due unused argument (`RzAnalysis` was not used) - Add new method `rz_analysis_var_count_total` to simplify some usages - Remove `rz_core_graph_diff` - Add `typedef RzAnalysisFcnType` on `enum``used for function types - Remove unused `RZ_ANALYSIS_FCN_VARKIND_LOCAL` - Remove from `RzAnalysisFunction` the following variables: * `fingerprint` * `fingerprint_size` * `diff` * `diff_ops` * `diff_thbb` * `diff_thfcn` - Remove from `RzAnalysisBlock` the following variables: * `fingerprint` * `diff` - Remove `RZ_ANALYSIS_THRESHOLDBB` and `RZ_ANALYSIS_THRESHOLDFCN` - Remove the following callbacks from `RzAnalysisPlugin` * `RzAnalysisDiffBBCallback` * `RzAnalysisDiffFcnCallback` * `RzAnalysisDiffEvalCallback` - Fix fancy table columns/rows when a color string is in a cell - Bumped project version to 9
