* rebasing on master to implement --followcalls * in progress changes to enable --followcalls * rebase to master: modified function to add children to funcs array * modify main traversal loop * added tests to check different scenarios * added tests to check different scenarios * added tests to check different scenarios * add test to check for overlapping regular expression * modified type of strings array as a return only * changed depth to a simple integer instead of a global map * avoid calling traverse on recursive calls * Added tests for various call graphs to test trace followfuncs * Added tests for various call graphs to test trace followfuncs * Added tests for various call graphs to test trace followfuncs * made auxillary changes for build to go through for new option follow-calls * Add support to print depth of the function calls as well * Added two sample output files for checking * Bypass morestack_noctxt in output for verification testing * Corrected newline error by adding newlines only if the line does not match morestack_noctxt * Added more tests * Cleanup * Updated documentation * fixed error message in fmt.Errorf * Fixed result of Errorf not used error * Addressing review comments to fix depth reporting and other issues * dont invoke stacktrace if tracefollowcalls is enabled, compute depth from main regex root symbol than main.main * Addressing a part of review comments * Added changes to allow deferred functions to be picked up for tracing * Fix issue to avoid printing stack for a simple trace option * Moving most tests to integration2_test.go and keeping only one in dlv_test.go * Moving most tests to integration2_test.go and keeping only one in dlv_test.go * Adding panic-defer test case * Moved rest of the tests to integration2_test.go * addressing review comments: folding Functions and FunctionsDeep, reducing branches by using depth prefix, wrap using %w and other comments * Optimize traversal and parts of printing trace point function and modify trace output layout and adjust tests accordingly * Resolved error occurring due to staticcheck * Implemented traversal algorithm using breadth first search * Addressing review comments on the breadth first search implementation and other comments * Inline filterRuntimeFuncs and remove duplicate initialization
