2018-04-26[stdlib/sys]: install one debug function more times (#1781)Pouriya
Allow installing multiple instances of sys debug function This commit solves a bug which allowed installing {Fun,State} as sys debug function even if Fun was already installed. This happened in the case when the current State of the debug fun was undefined. Also, the new format {Id,Fun,State} of debug functions can be installed, allowing multiple instances of the same fun.

2018-04-25stdlib: Modify the printing of map associations with wWpPHans Bolinder
Use the same depth for all (printed) elements of a map. Since the order of keys can vary when printing a map--maps:iterator/1 and maps:next/1 are used--it is more consistent to print all associations with the same depth. If the associations printed are limited by the depth, the selection of associations is arbitrary, as before.
2018-04-25stdlib: Introduce characters limit of formated stringsHans Bolinder
Inspiration from module lager_format. Also some improvements of Unicode handling. io_lib:format/3 and io_lib:fwrite/3 are new functions. The representation of the options is a list, but we are considering using a map instead. If we change, it will happen after Erlang/OTP 21.0-rc1 is released.

2018-04-25Rewrite a call of a literal external fun to a direct callBjörn Gustavsson
Rewrite calls such as: (fun erlang:abs/1)(-42) to: erlang:abs(-42) While we are at it, also add rewriting of apply/2 with a fixed number of arguments to a direct call of the fun. For example: apply(F, [A,B]) would be rewritten to: F(A, B) https://bugs.erlang.org/browse/ERL-614
2018-04-25stdlib: Modify ~w/~W when number of characters is limitedHans Bolinder
A bug fix: limited maps end with "...", not "...=>...". A modification: wW separate pairs with " => ", not "=>". When the output is limited on number of characters, the term is balanced by wW the same way as is done with pP (see commit bc38638).

The name of the io_lib_pretty:print/2 option 'max_chars' is changed to 'line_max_chars' (used by module shell only). The new option for limiting the number of returned characters of io_lib_pretty:print() is called 'chars_limit'.

2018-04-24Introduce map_get guard-safe functionMichał Muskała
Rationale Today all compound data types except for maps can be deconstructed in guards. For tuples we have `element/2` and for lists `hd/1` and `tl/1`. Maps are completely opaque to guards. This means matching on maps can't be abstracted into macros, which is often done with repetitive guards. It also means that maps have to be always selected whole from ETS tables, even when only one field would be enough, which creates a potential efficiency issue. This PR introduces an `erlang:map_get/2` guard-safe function that allows extracting a map field in guard. An alternative to this function would be to introduce the syntax for extracting a value from a map that was planned in the original EEP: `Map#{Key}`. Even outside of guards, since this function is a guard-BIF it is more efficient than using `maps:get/2` (since it does not need to set up the stack), and more convenient from pattern matching on the map (compare: `#{key := Value} = Map, Value` to `map_get(key, Map)`). Performance considerations A common concern against adding this function is the notion that "guards have to be fast" and ideally execute in constant time. While there are some counterexamples (`length/1`), what is more important is the fact that adding those functions does not change in any way the time complexity of pattern matching - it's already possible to match on map fields today directly in patterns - adding this ability to guards will niether slow down or speed up the execution, it will only make certain programs more convenient to write. This first version is very naive and does not perform any optimizations.
