Aerc usually used the path []int{1} if it didn't know what the proper path is.
However this only works for multipart messages and breaks if it isn't one.
This patch removes all the hard coding and extracts the necessary helpers to lib.
When message dates failed to parse, the error displayed would try to
include the time object it failed to obtain, which would display as
something like 0001-01-01 00:00:00 UTC, which isn't of much help.
Instead, display the text we were trying to parse into a date, which
makes the problem easier to debug.
There was an unused error value as well as unnecessary usage of the sort
interface. There should now be less copying so a bit better performance
in some cases.
There is a command and config option. The criteria are a list of the
sort criterion and each can be individually reversed.
This only includes support for sorting in the maildir backend currently.
The other backends are not supported in this patch.
Things like FetchEntityPartReader etc can be reused by most workers
working with raw email files from disk (or any reader for that matter).
This patch extract that common functionality in a separate package.
