61c3ad6791 read_verilog: allow width detect to fail for unreachable ternary branch 
Cannot skip width detection entirely as unreachable branch (if it is
a legal expression) may still be used to determine width of result

ac10e7d96d Initial implementation of elaboration system tasks 
(IEEE1800-2017 section 20.11)
This PR allows us to use $info/$warning/$error/$fatal **at elaboration time** within a generate block.
This is very useful to stop a synthesis of a parametrized block when an
illegal combination of parameters is chosen.

c50afc4246 Documentation improvements etc. 
- Mention new feature in the SystemVerilog section in the README file
- Commented changes much better
- Rename a few signals to make it clearer
- Prevent warning for unused signals in an easier way
- Add myself as copyright holder to 2 files
- Fix one potential memory leak (delete 'wire' if not in modport)

68b5d0c3b1 Convert more log_error() to log_file_error() where possible. 
Mostly statements that span over multiple lines and haven't been
caught with the previous conversion.

b5ea598ef6 Use log_file_warning(), log_file_error() functions. 
Wherever we can report a source-level location.

Henner Zeller
1a60126a34 Provide source-location logging. 
o Provide log_file_warning() and log_file_error() that prefix the log
  message with <filename>:<lineno>: to be easily picked up by IDEs that
  need to step through errors.
o Simplify some duplicate logging code in kernel/log.cc
o Use the new log functions in genrtlil.
