Add dirname of script file to sys.path
...
This matches the behavior of running a Python interpreter, where the
first element of sys.path is the dirname of the script being run.
This allows importing of files and modules in the same directory without
messing with PYTHONPATH or similar.

-y flag for libyosys Python scripts
...
This adds a Python equivalent to the `-c` option, where scripts importing `libyosys` can be imported and used.
Most of the work for this was already done to enable Python passes a couple years back, so this is a relatively small changeset.

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).

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)`.

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`.
