This adds two new macros, `p_req_tal()` and `p_opt_tal()`. These support
callbacks that take a `struct command *` context. Example:
static bool json_tok_label_x(struct command *cmd,
const char *name,
const char *buffer,
const jsmntok_t *tok,
struct json_escaped **label)
The above is taken from the run-param unit test (near the bottom of the diff).
The return value is true on success, or false (and it calls command_fail itself).
We can pretty much remove all remaining usage of `json_tok_tok` in the codebase
with this type of callback.
The easiest way to do this is to play with the 'wallet_tx' semantics
and have 'amount' have meaning even when 'all_funds' is set.
Note that we change the string 'Cannot afford funding transaction' to
'Cannot afford transaction' as this code is also used for withdrawls.

Developer errors result in command_fail being called
just like other errors. The bad_programmer() Test is now updated
and passing.

They now just call command_fail() and cause param() to return false.
Temporarily disabled all the run-param.c tests that redirect
asserts so CI would still pass.

Removed `json_get_params`.
Also added json_tok_percent and json_tok_newaddr. Probably should
have been a separate PR but it was so easy.
