These changes decode valid SIGHASH types on signatures in assembly (asm) representations of scriptSig scripts. This squashed commit incorporates substantial helpful feedback from jtimon, laanwj, and sipa.

Notable changes
Random-cookie RPC authentication
When no -rpcpassword is specified, the daemon now uses a special 'cookie'
file for authentication. This file is generated with random content when the
daemon starts, and deleted when it exits. Its contents are used as
authentication token. Read access to this file controls who can access through
RPC. By default it is stored in the data directory but its location can be
overridden with the option -rpccookiefile.
This is similar to Tor's CookieAuthentication: see https://www.torproject.org/docs/tor-manual.html.en
This allows running bitcoind without having to do any manual configuration.
Low-level RPC API changes
- Monetary amounts can be provided as strings. This means that for example the argument to sendtoaddress can be "0.0001" instead of 0.0001. This can be an advantage if a JSON library insists on using a lossy floating point type for numbers, which would be dangerous for monetary amounts.

RPC and REST
Asm representations of scriptSig signatures now contain SIGHASH type decodes
The asm property of each scriptSig now contains the decoded signature hash
type for each signature that provides a valid defined hash type.
The following items contain assembly representations of scriptSig signatures and are affected by this change:
- RPC
getrawtransaction - RPC
decoderawtransaction - REST
/rest/tx/(JSON format) - REST
/rest/block/(JSON format when including extended tx details) bitcoin-tx -json
For example, the scriptSig.asm property of a transaction input that
previously showed an assembly representation of:

now shows as:
304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c5090[ALL]
Note that the output of the RPC decodescript did not change because it is
configured specifically to process scriptPubKey and not scriptSig scripts.
