Rusty Russell 391da2f440 lightningd: don't let them fundpsbt below emergency reserve.
This is the simple version which always tries to keep some sats if we
have an anchor channel.  Turns out that we need something more
sophisticated for multifundchannel, so that's next.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: JSON-RPC: `withdraw` will refuse to spend funds below `min-emergency-msat` if we have any anchor channels (and `all` will be reduced appropriately).
Changelog-Changed: JSON-RPC: `fundpsbt` and `utxopsbt` will refuse to spend funds below `min-emergency-msat` if we have any anchor channels.

lightning-withdraw -- Command for withdrawing funds from the internal wallet
============================================================================
SYNOPSIS
--------
**withdraw** *destination* *satoshi* [*feerate*] [*minconf*] [*utxos*]
DESCRIPTION
-----------
The **withdraw** RPC command sends funds from Core Lightning's internal
wallet to the address specified in *destination*.
The address can be of any Bitcoin accepted type, including bech32.
*satoshi* is the amount to be withdrawn from the internal wallet
(expressed, as name suggests, in satoshi). The string *all* can be used
to specify withdrawal of all available funds (but if we have
any anchor channels, this will always leave at least `min-emergency-msat` as change).
. Otherwise, it is in
satoshi precision; it can be a whole number, a whole number ending in
*sat*, a whole number ending in *000msat*, or a number with 1 to 8
decimal places ending in *btc*.
*feerate* is an optional feerate: see NOTES in lightning-feerates(7)
for possible values. The default is *normal*.
*minconf* specifies the minimum number of confirmations that used
outputs should have. Default is 1.
*utxos* specifies the utxos to be used to be withdrawn from, as an array
of "txid:vout". These must be drawn from the node's available UTXO set.
RETURN VALUE
------------
[comment]: # (GENERATE-FROM-SCHEMA-START)
On success, an object is returned, containing:
- **tx** (hex): the fully signed bitcoin transaction
- **txid** (txid): the transaction id of *tx*
- **psbt** (string): the PSBT representing the unsigned transaction
[comment]: # (GENERATE-FROM-SCHEMA-END)
On failure, an error is reported and the withdrawal transaction is not
created.
The following error codes may occur:
- -1: Catchall nonspecific error.
- 301: There are not enough funds in the internal wallet (including
fees) to create the transaction.
- 302: The dust limit is not met.
- 313: The `min-emergency-msat` reserve not be preserved (and we have anchor channels).
