Merge pull request #4802 from povik/abc9-box-repeat 
Adjust `abc9_ops -prep_box` to allow repeated invocation

2a3f60bc06 abc_new: Support abc9_box mode on ordinary design hierarchy 
Previously the `abc9_box` mode was reserved to modules with the
`blackbox` or `whitebox` attribute. Allow `abc9_box` on ordinary modules
when doing hierarchical synthesis.

481d596c43 abc9_ops -prep_box: Adjust for repeated invocation 
`abc9_ops -prep_box` command interprets the `abc9_box` attribute and
prepares a .box file for ABC consumption. Previously this command was
removing the attribute as it was processing each module which prevented
repeated invocation of this command unless the box definitions were
refreshed from a source file.

Also the command was keeping existing `abc9_box_id` attributes instead
of overwriting them with values from a new number sequence.

Change both behaviors to allow repeated invocations of the command on
the same design.

9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

c4cc888b2c kernel/rtlil: Extract some helpers for checking memory cell types. 
There will soon be more (versioned) memory cells, so handle passes that
only care if a cell is memory-related by a simple helper call instead of
a hardcoded list.
