Disable some trace messages which appeared a lot in the output and probably
aren't so useful any more, when block processing is functioning well at high
speed.
Turning on the trace level globally is useful to get a feel for what's
happening, but only if each category is kept to a reasonable amount.
As well as overwhelming the output so that it's hard to see general activity,
some of these messages happen so much they severely slow down processing. Ones
called every time an EVM opcode uses some gas are particularly extreme.
These messages have all been chosen as things which are probably not useful any
more (the relevant functionality has been debugged and is tested plenty).
These have been commented out rather than removed. It may be that turning
trace topics on/off, or other selection, is a better longer term solution, but
that will require better command line options and good defaults for sure.
(I think higher levels `tracev` and `tracevv` levels (extra verbose) would be
more useful for this sort of deep tracing on request.)
For now, enabling `--log-level:TRACE` on the command line is quite useful as
long as we keep each category reasonable, and this patch tries to keep that
balance.
- Don't show "has transactions" on virtually every block imported.
- Don't show "Sender" and "txHash" lines on every transaction processed.
- Don't show "GAS CONSUMPTION" on every opcode executed", this is way too much.
- Don't show "GAS RETURNED" and "GAS REFUND" on each contract call.
- Don't show "op: Stop" on every Stop opcode, which means every transaction.
- Don't show "Insufficient funds" whenever a contract can't call another.
- Don't show "ECRecover", "SHA256 precompile", "RIPEMD160", "Identity"
or even "Call precompile" every time a precompile is called. These are
very well tested now.
- Don't show "executeOpcodes error" whenever a contract returns an error.
(This is changed to `trace` too, it's a normal event that is well tested.)

The common forks list was already used, redirected via `vm_forks` for
historical compatibility. Remove the old `vm_forks` now and divert all imports
to the common forks list outside the EVM.

why:
it was convenient to have relocatable source modules when writing the
vm interface wrappers. this patch moves it back to the standard.
also:
there are no deep links into the vm folder anymore which leaves some
room for manoeuvring inside
why:
the nvm_ prefix was used inside the vm folder to hide them temporarily
from the outside world while writing export wrappers. now all
functionality is accessed via vm_*, rather than vm/* imports.
todo:
at a later stage the import headers of the vm modules need to get fixed
to meet style guide standards (as jacek kindly pointed out.)
why:
relative paths make sources inherently non-relocatable
details:
import base is set to the nimbus directoy, so importing ./stack
from file interpreter.nim becomes vm/stack etc.
caveat:
a file named nimbus/strformat.nim would clash with strformat (but
not with std/strformat)
