e0ae7b7af4 Remove .c_str() calls from log()/log_error() 
There are some leftovers, but this is an easy regex-based approach that removes most of them.

Reduce comparisons of size_t and int 
`Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`.
For cases where size is being explicitly cast to `int`, use the wrapper that we already have instead: `Yosys::GetSize()`.

c0063288d6 Add the $anyinit cell and the formalff pass 
These can be used to protect undefined flip-flop initialization values
from optimizations that are not sound for formal verification and can
help mapping all solver-provided values in witness traces for flows that
use different backends simultaneously.

9d41aa8e28 Avoid unnecessary copy of a potential large constant value. 
The local variable is used just to iterate through the values, so
a const reference is all we need.

28b9f49c94 fsm_extract: avoid calling log_signal to determine wire name 
log_signal can result in a string with spaces (when bit selection is
involved), which breaks the rule of IdString not containing whitespace.
Instead, remove the sigspec from the name entirely — given that the
resulting wire will have no users, it will be removed later anyway,
so its name doesn't really matter.

Fixes #2118

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.

3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
