Merge branch 'aronisstav/dialyzer/dialyzer_tests/OTP-9116' into dev
* aronisstav/dialyzer/dialyzer_tests/OTP-9116: Increase timetrap of options1 suite Write output_plt even when plt_check is ok Create plt with erts, kernel and stdlib only Update test results as they currently appear in dev Major restructure of dialyzer's testsuite Add 'apps' option to the erlang interface Update spec file to work with new common test structure Test suites for Dialyzer

+%% usage: pretty_format:term(Term) -> PNF list of characters
+%%
+%% Note: this is usually used in expressions like:
+%% io:format('~s\n',[pretty_format:term(Term)]).
+%%
+%% Uses the following simple heuristics
+%%
+%% 1) Simple tuples are printed across the page
+%% (Simple means *all* the elements are "flat")
+%% 2) The Complex tuple {Arg1, Arg2, Arg3,....} is printed thus:
+%% {Arg1,
+%% Arg2,
+%% Arg3,
+%% ...}
+%% 3) Lists are treated as for tuples
+%% 4) Lists of printable characters are treated as strings
+%%
+%% This method seems to work reasonable well for {Tag, ...} type
+%% data structures
