None of the existing callbacks was making use of it and we will be
exposing the method callback interface to outside compilation unit
where the struct definition is not visible. So just remove it.

I might have gone a bit overboard with the type-checking, but
typesafe_cb_cast is quite nice to use, so why not. The macro to
register a new hook encapsulates the entire flow from param
serialization, to dispatch, parsing and callback dispatch in one
bundle. I was tempted to have the callback outside of the
registration, but it's unlikely that we'll have two calls to the same
hook with different callbacks.

Instead of creating a new map I opted to re-use the Plugin.methods
map, since the semantics are really similar and we don't allow
duplicates. The only difference is in how they are announced to
lightningd, so we use an enum to differentiate rpcmethods from hooks,
since only the former will get added to the JSON-RPC dispatch table in
lightningd.

The cause was that converting a block number to an scid truncates it
at 24 bits. When we look through the index from (truncated number) to
(real end number) we get every channel, which is too large to encode,
so we iterate again.
This fixes both that problem, and also the issue that we'd end up
dividing into many empty sections until we get to the highest block
number. Instead, we just tack the empty blocks on to then end of the
final query.
(My initial version requested 0xFFFFFFFE blocks, but the dev code
which records what blocks were returned can't make a bitmap that big
on 32 bit).

We used to have a bug where decoderawtransaction would fail, fixed in
fedcfd661 (pytest: hand 'True' to decoderawtransaction so it doesn't
get confused.).
So we can remove the fallback decode, and might as well extract the
ugliness into a helper function.

We didn't populate the channels properly so it always failed.
Additionally, somewhere along the line we kept using the single scid
so we only created one channel.
Also, the next patch will start comparing the pubkeys, so make valid
ones: use an array so we don't affect the benchmark too much.

seed isn't very useful at this level: I've left it in routing.c
because it might be useful for detailed testing. Pretty sure it's unused,
so I simply removed it.
The fuzzpercent is documented to default at 5%, but actually was 75%.
Fix that too.

Christian and I both unwittingly used it in form:
*tal_arr_expand(&x) = tal(x, ...)
Since '=' isn't a sequence point, the compiler can (and does!) cache
the value of x, handing it to tal *after* tal_arr_expand() moves it
due to tal_resize().
The new version is somewhat less convenient to use, but doesn't have
this problem, since the assignment is always evaluated after the
resize.

After this code change people can use `plugin.rpc` from anywhere in
their plugin code this is much nicer than going this way:
```
@plugin.method("init")
def init(options, configuration, plugin):
global rpc
basedir = plugin.lightning_dir
rpc_filename = plugin.rpc_filename
path = os.path.join(basedir, rpc_filename)
rpc = LightningRpc(path)
```
or similarly that way:
```
@plugin.method("init")
def init(options, configuration, plugin):
global rpc
basedir = configuration['lightning-dir']
rpc_filename = configuration['rpc-file']
path = os.path.join(basedir, rpc_filename)
rpc = LightningRpc(path)
```
Also the imports have been sorted alphabetically

Teach `lightning-cli help` to look in the doc directory relative to
lightning-cli if it can't find the manpage in any man paths.
This makes `lightning-cli help` work even if clightning hasn't been installed
