9441c5e77b rpc: split README into developer and user parts 
Most of the document is written for developers and thus belongs to
godoc. User-related document is now moved to docs as per #339.

Merge pull request #402 from nspcc-dev/tiny-technical-corrections 
This one updates go.mod/go.sum (as any build at the moment gives changes
to these files) and makes some source code files non-executable.

Merge pull request #400 from nspcc-dev/move-rw-to-io 
Move BinReader/BinWriter to io and simplify things

BinReader and BinWriter don't belong to util, actually util shouldn't
exist at all. Moving them to io and using them for all encoding/decoding
purposes allows to simplify a lot of code, especially in the error
handling space. These interfaces are designed to absorb errors until
someone can do something meaningful with them (usually that's the top
caller of encode/decode functions) and our current use of them is
inconsistent.

This patchset moves BinReader/BinWriter and size calculations (that
are mostly about Serializable things) to io package and makes all the
other code use them for encoding/decoding purposes.

0bb8950f89 make TXer and Payload implement Serializable 
Both are duplicating Serializable at the moment, but let's keep them for the
future.

e299a44983 io: drop Size() method from Serializable and associated 
It's no longer needed after the io.GetVarSize() improvement. It's duplicating
a lot of EncodeBinary() logic also.

56c72b5c67 io: redo GetVarSize for Serializable things 
Use writes to a fake io.Writer that counts the bytes. Allows us to kill Size()
methods as useless and duplicating lots of functionality.

0da9fe6946 io: move size calculator there 
It's mostly used for Serializable and in other cases where one needs to
estimate binary-encoded size of the stucture. This also simplifies future
removal of the Size() from Serializable.

5bf00db2c9 io: move BinReader/BinWriter there, redo Serializable with it 
The logic here is that we'll have all binary encoding/decoding done via our io
package, which simplifies error handling. This functionality doesn't belong to
util, so it's moved.

This also expands BufBinWriter with Reset() method to fit the needs of core
package.

Merge pull request #396 from nspcc-dev/network-reconnections-and-fixes 
This one fixes #390 and some connected problems. After this patchset the node reconnects to some other nodes if anything goes wrong and it better senses when something goes wrong. It also fixes some block handling problems based on the testnet connection experience.

773ccc2b92 network: allow discoverer to reuse addresses 
...and don't try to connect to the nodes we're already connected to.

Before this change we had a problem of discoverer throwing away good valid
addresses just because they are already known which lead to pool draining over
time (as address reuse was basically forbidden and getaddr may not get enough
new nodes).

46dc141c6c network: enlarge address request queue 
Queuing one message is not reliable enough, the peer that gets it can fail to
actually make a request, so make this queue a bit deeper to have a higher
chance of success.

d3bb8ddf8f network: handle errors and connection close more correctly 
This makes writer side handle errors properly and fixes communication between
reader and writer goroutine to always correctly unregister the peer. This is
especially important for the case where error occurs before handshake
completes as in this case we don't even have goroutine in startProtocol()
running.

c6487423ae network: close connection on disconnect 
If it's already closed, this won't hurt, but in the case of logical error it
saves us from leaking this connection (and potentially, peer).
