Jannis Harder 56572978f5 drivertools: Utility code for indexing and traversing signal drivers 
It adds `DriveBit`, `DriveChunk` and `DriveSpec` types which are similar
to `SigBit`, `SigChunk` and `SigSpec` but can also directly represent
cell ports, undriven bits and multiple drivers. For indexing an RTLIL
module and for querying signal drivers it comes with a `DriverMap` type
which is somewhat similar to a `SigMap` but is guaranteed to produce
signal drivers as returned representatives.

A `DriverMap` can also optionally preserve connections via intermediate
wires (e.g. querying the driver of a cell input port will return a
connected intermediate wire, querying the driver of that wire will
return the cell output port that's driving the wire).

Jannis Harder f24e2536c6 kernel/rtlil: Add `SigBit operator[](int offset)` to `SigChunk` 
This is already supported by `SigSpec` and since both `SigChunk` and
`SigSpec` implement `extract` which is the multi-bit variant of this,
there is no good reason for `SigChunk` to not support
`SigBit operator[](int offset)`.

Jannis Harder c73c8a39cf kernel/log: Add log_str helper for custom log_* functions/overloads 
When implementing custom log_... functions or custom overloads for the
core log functions like log_signal it is necessary to return `char *`
that are valid long enough.

The log_... functions implemented in log.cc use either `log_id_cache` or
`string_buf` which both are cleared on log_pop.

This commit adds a public `log_str` function which stores its argument
in the `log_id_cache` and returns the stored copy, such that custom
log functions outside of log.cc can also create strings that remain
valid until the next `log_pop`.

Jannis Harder 0922142567 Add generic topological sort and SCC detection 
This adds a generic non-recursive implementation of Tarjan's linear time
SCC algorithm that produces components in topological order. It can be
instantiated to work directly on any graph representation for which the
enumerate_nodes and enumerate_successors interface can be implemented.

KrystalDelusion 3dd32d741a Stop unconditionally building abc 
_What are the reasons/motivation for this change?_
abc builds unconditional because `check-git-abc` is a phony prerequisite and therefore always runs, and since it always runs it will always trigger abc to rebuild.

_Explain how this is achieved._
Convert `check-git-abc` to an order-only prerequisite.  It still runs as before, but no longer triggers yosys-abc to rebuild when it does.

_If applicable, please suggest to reviewers how they can test the change._
