efa278e232 Fix typographical and grammatical errors and inconsistencies. 
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.

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)

042b3074f8 Added -no_dump_ptr flag for AST dump options in 'read_verilog' 
This option disables the memory pointer display.
This is useful when diff'ing different dumps because otherwise the node pointers
makes every diff line different when the AST content is the same.

Merge pull request #513 from udif/pr_reg_wire_error 
Add error checking for reg/wire/logic misuse - PR now passes 'make test' (plus a new test)

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.

2b9c75f8e3 This PR should be the base for discussion, do not merge it yet! 
It correctly detects reg/wire mix and incorrect use on blocking,nonblocking assignments within blocks and assign statements.

What it DOES'T do:
Detect registers connected to output ports of instances.

Where it FAILS:
memorty nonblocking assignments causes spurious (I assume??) errors on yosys-generated "_ADDR", "_DATA", "EN" signals.

You can test it with tests/simple/reg_wire_error.v (look inside for the comments to enable/disable specific lines)
