Use dedicated type for error codes Before this patch we used `int` for error codes. The problem with `int` is that we try to pass it to/from wire and the size of `int` is not defined by the standard. So a sender with 4-byte `int` would write 4 bytes to the wire and a receiver with 2-byte `int` (for example) would read just 2 bytes from the wire. To resolve this: * Introduce an error code type with a known size: `typedef s32 errcode_t`. * Change all error code macros to constants of type `errcode_t`. Constants also play better with gdb - it would visualize the name of the constant instead of the numeric value. * Change all functions that take error codes to take the new type `errcode_t` instead of `int`. * Introduce towire / fromwire functions to send / receive the newly added type `errcode_t` and use it instead of `towire_int()`. In addition: * Remove the now unneeded `towire_int()`. * Replace a hardcoded error code `-2` with a new constant `INVOICE_EXPIRED_DURING_WAIT` (903). Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2

lightningd: expand exit codes for various failures. Most unexpected ones are still 1, but there are a few recognizable error codes worth documenting. Rename the HSM ones to put ERRCODE_ at the front, since we have non-HSM ones too now. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
