Start up of SASl when compared log level is all

* kpy3/fix-fd-leak-in-logger/OTP-15997:
  Close log files in case of inode change properly

Allowed SASL startup when compared levels include all/none as per PR 2301.

This was achieved by adding another macro for this (?IS_LEVEL_ALL); documentation updated to show the change

Added the (re-) added net module to the application app file.

Before:

1> gen_udp:open(0, [local, {ip, {local, "unixdomainfile"}}]).
{ok,#Port<0.6>}
2> inet:i().
** exception error: bad argument
     in function  integer_to_list/1
        called as integer_to_list(<<"unixdomainfile">>)
     in call from inet:fmt_port/2 (inet.erl, line 1646)
     in call from inet:fmt_addr/2 (inet.erl, line 1642)
     in call from inet:'-i_line/3-lc$^0/1-0-'/3 (inet.erl, line 1547)
     in call from inet:'-i_line/3-lc$^0/1-0-'/3 (inet.erl, line 1547)

     in call from inet:ii/3 (inet.erl, line 1531)
     in call from inet:i/0 (inet.erl, line 1515)

After:

Port Module    Recv Sent Owner      Local Address           Foreign Address State Type
4160 local_udp 0    0    <0.1747.0> local:unixdomainfile    *:*             IDLE  DGRAM

Also needed to take care of the specs files (in erts and kernel docs).
Also, ifdef'ing the net module adjusted (again).

Still trying to make --disable-esock to work properly.
Now the primary chore is the doc building.
