All Notary contract witnesses in incomplete transaction (both main
and fallback) may either have invocation scripts pushing dummy signature
on stack or be empty, both ways are OK. Notary actor keeps main tx's
Notary witness empty and keeps fallback tx's Notary witness filled
with dummy signature.

Our wrapping optimization relied on the caller context having a TRY block,
but each context (including internal calls!) has an exception handling stack
of its own, which means that for an invocation stack of
entry
A.someMethodFromEntry() # this one has a TRY
A.internalMethodViaCALL() # this one doesn't
B.someMethod()
we get `HasTryBlock() == false` for `A.internalMethodViaCALL()` context, which
leads to missing wrapper and missing rollbacks if B is to THROW. What this
patch does instead is it checks for any context within contract boundaries.
Fixes#3045.

That's the way how C# node handles equality checks for stackitem.Interop types
for these points. Ref. https://github.com/nspcc-dev/neo-go/issues/3002#issuecomment-1591220501.
Along the way, add GT case for CryptoLib's bls12381Equal method. It should be there since #2940.

In this case emitted event parameters should match from invocation to
invocation. It's an error otherwise (and if the type is not Any).

Currently we have problems with unnamed structs used as a parameter for
notifications, because there's no one-to-one correspondence between
notification parameter and the list of extended types used by the whole
contract. Otherwise eventtypes guessing works OK.

config_extended.yml contains an example of user-defined configuration
file with extended event types. User-defined event types are allowed
to be named and complicated, i.e. properly support extended types
notation.

Unfortunately, without pre-set user extended types configuration for events
and without --guess-eventtypes flag set we are allowed to rely only on manifest
information about types. Manifest can't give us a lot of information, but we
still need to be able to generate RPC binding. Arrays and structs are correctly
handled by the current code, but maps always rely on the fact that map's value
type is set. It's not true in the described case, so make the maps type convertor
handle this situation in a similar way how arrays are handled.
Without this commit the following panic occurs on attempt to generate RPC binding:

There are two ways of doing this: first one is to emit all notifications
parameter data into rpcbindings configuration on compile time (event if
the parameter has a simple type), and the second one is to fetch parameter
type from the manifest on rpcbinding file generation if needed (we always
have manifest at this stage, thus it's not a problem to retrieve necessary
information). The latter case is chosen to reduce the bindings configuration
file size.

Notification and its parameters may have any UTF8-compatible name
which is inappropriate for bindings configuration and for the resulting
RPC bindings file. This commit stores the prettified version of
notification's name and parameters that are ready to be used in the
resulting RPC binding without any changes.

The user should specify it via parameter's `extendedtype` field and
via upper-level `namedtypes` field of the contract configuration YAML.
Also, as we have proper event structure source, make the `--guess-eventtype`
compilation option and make event types guess optional.

New rule for writing blocks of code to our template: new line before
the block starts and new line after the block ends. This rule is the
same as the one we use during manual typing.

cli's testdata folder stores contracts examples and expected compilation
output, thus doesn't need to be ignored.
*.out files are the bindings outputs only, do not ignore them as far.
