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.

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).

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

docs: Update manpages to be recognized correctly by mrkd

mrkd started enforcing the `name -- short description` style of top-level
headings somewhere, and was thus failing to build the man-pages. I swapped
the title and with the existing short description to make it work
again. `mrkd` will automatically infer the section from the filename so no
need to put it in the title as well.

In addition I removed the "last updated" lines at the bottom since they are
out of date at best, and misleading at the worst. If we want to keep them, I'd
suggest generating them from the commit that last touched them.
