Marcelina Kościelnicka 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

whitequark ff5500f11a cxxrtl: rename cxxrtl.cc→cxxrtl_backend.cc. 
To avoid confusion with the C++ source files that are a part of
the simulation itself and not a part of Yosys build.

whitequark 31f6c96b1f cxxrtl: add a C API for writing VCD dumps. 
This C API is fully featured.

whitequark 68362a9053 cxxrtl: only write VCD values that were actually updated. 
On a representative design (Minerva SoC) this reduces VCD file size
by ~20× and runtime by ~3×.

whitequark c399359ed6 cxxrtl: add a C API for driving and introspecting designs. 
Compared to the C++ API, the C API currently has two limitations:
  1. Memories cannot be updated in a race-free way.
  2. Black boxes cannot be implemented in C.

whitequark f6e16e7f4c cxxrtl: generate debug information for non-localized public wires. 
Debug information describes values, wires, and memories with a simple
C-compatible layout. It can be emitted on demand into a map, which
has no runtime cost when it is unused, and allows late bound designs.

The `hdlname` attribute is used as the lookup key such that original
names, as emitted by the frontend, can be used for debugging and
introspection.

whitequark 6268bdfe6f flatten: simplify. 
`flatten` cannot derive modules in most cases because that would just
yield processes, and it does not support `-autoproc`; in practice
`flatten` has to be preceded by a call to `hierarchy`, which makes
deriving unnecessary.

whitequark 6ac54a74fe flatten: split from techmap. 
Although the two passes started out very similar, they diverged over
time and now have little in common. Moreover, `techmap` is extremely
complex while `flatten` does not have to be, and this complexity
interferes with improving `flatten`.
