2017-02-03dialyzer: Do not spawn all workers at onceHans Bolinder
Spawning all worker processes at once has the potential to increase peak memory consumption. Therefore the implementation is now slightly modified: `20 * dialyzer_utils:parallelism()' processes are running in parallel. 20 i quite a big factor, but seems necessary to keep all schedulers busy according to the Observer application's Load Charts, with a 100 ms update interval.
2017-02-03dialyzer: Write PLT in subprocessHans Bolinder
At common case, which will otherwise leave a big heap.
2017-02-03dialyzer: Remove code for non-started workersHans Bolinder
Since SCCs and modules are now topologically sorted (relative the active graph), we can safely assume that workers have been started.
2017-02-03dialyzer: Sort graphs topologicallyHans Bolinder
Although some variable names indicate that lists of SCCs and modules are sorted, that was not always the case. The effect on the execution time of sorting them doesn't seem to be significant. dialyzer_coordinator:sccs_to_pids() should now always return an empty second list (not yet started workers). Since the condensation of graphs often needs a lot of heap memory, it is run in a separate process.
2017-02-03dialyzer: Compress some PLT tablesHans Bolinder
Compressing the signatures or the contract records would cost time. The contract records are still held in two places (code server and PLT) in many cases.
2017-02-03dialyzer: Check return value of digrahp:add_edge()Hans Bolinder
2017-02-03dialyzer: Use less memory for the PLT when analyzingHans Bolinder
The two tables for (record) types and exported types are no longer kept in memory (by the PLT) when analyzing, which reduces memory consumption. A first step towards removing (or replacing) the #plt{} record.
2017-02-03typer: Fix a bug regarding the -T optionHans Bolinder
The -T option has not been working for a long time.
2017-02-03dialyzer: Do not keep the code server's type info on the heapHans Bolinder
The table used during translation of forms to types used to be a dictionary of the type info (-type(), -opaque(), and -record()) for all modules. Now it is reduced to the modules that are needed to handle references to types in other modules. The PLT:s type info is still kept on the heap.

2017-02-01ssl: Simplify configuration codeIngela Anderton Andin
Use map instead of large tuple, which was not an option when the code was written originally. More simplifications along these lines may be done later to the state record.
2017-02-01ssl: Make sure PEM cache works as intendedIngela Anderton Andin
Move of PEM cache to own process was flawed and not all PEM files where cached properly. We must properly handle both the ditributed and the normal mode of the ssl application.

2017-02-01dialyzer: Optimize typesigHans Bolinder
dialyzer_typesig:traverse_scc() now resets the context for each element of the SCC. Since the results of traversing the elements are saved in the 'cmap' table, there is no need to create an SCC conjunction. For huge SCCs this saves quite some time: the lift_lists() function added one element at a time, which made the calculation of deps very slow.

Set fixtable false will fail on deleted tables, catch that and also report checkpoint deactivate error, so user can see why checkpoint was deactivated and backup fails.
