* p2p: add low port check in dialer

We already have a check like this for UDP ports, add a similar one in
the dialer. This prevents dials to port zero and it's also an extra
layer of protection against spamming HTTP servers.

* p2p/discover: use errLowPort in v4 code

* p2p: change port check

* p2p: add comment

* p2p/simulations/adapters: ensure assigned port is in all node records

* core/rawdb: Stop freezer process as part of freezer.Close()

When you call db.Close(), it was closing the leveldb database first,
then closing the freezer, but never stopping the freezer process.
This could cause the freezer to attempt to write to leveldb after
leveldb had been closed, leading to a crash with a non-zero exit code.

This change adds a quit channel to the freezer, and freezer.Close()
will not return until the freezer process has stopped.

Additionally, when you call freezerdb.Close(), it will close the
AncientStore before closing leveldb, to ensure that the freezer goroutine
will be stopped before leveldb is closed.

This finally adds the error check that the documentation of StateDB.dbErr
promises to do. dbErr was added in 9e5f03b6 (June 2017), and the check was
already missing in that commit. We somehow survived without it for three years.

* Include 0x0000 address into the dump if it is present

* core/state: go fmt

* accounts/abi/bind: add void if no return args specified

Currently the java generator generates invalid input on pure/view functions
that have no return type. e.g. `function f(uint u) view public {}`
This is not a problem in practice as people rarely ever write functions like this.

This fixes an issue with clef, which already transforms the signature
to use the legacy 27/28 encoding.
