one might want to set `Inbox ~/Maildir` and `Path ~/Maildir/` to get a
self-contained ~/Maildir without resorting to `SubFolders Maildir++`,
though logical sub-folders are possible only with `SubFolders Legacy`.
also document that nesting Path into Inbox is supported in the first
place; amends 98bd2b11.
there is no need to call maildir_list_{path,inbox}() from
maildir_list_recurse(), as maildir_list_store() will do that anyway -
if it's actually requested, that is. this means that this removes the
implicit listing when Inbox is nested into Path, or vice versa. this is
actually correct, as the Patterns matching would throw away the non-
requested boxes anyway.
this finally makes us compliant with IMAP4rev1. how fitting that the
meanwhile released IMAP4rev2 demoted UTF-7 to legacy status ...
based on a patch by Georgy Kibardin <georgy@kibardin.name>.
the new one isn't an exhaustive set anymore, but a delta to the default
(or previous setting). this has the advantage that new versions aren't
automatically disabled anymore as soon as mbsync learns about them if
the user has a setting they fail to adjust.
report them as errors (not warnings), let them cause a non-zero exit
code, and in the case of trashing, prevent the subsequent expunge. the
exception are messages that just disappeared below our feet.
the purpose of these checks is preventing triggering more driver calls,
while immediate followups to already completed calls should be still
made.
note that some of the checks are strictly speaking redundant, as
chaining into a next phase will return immediately anyway when the
other side isn't ready yet. but we keep them for clarity.
this is only a partial solution for reporting changes, but it's
adequate if the goal is merely triggering a bulk action, like
re-indexing the local store.
inspired by patches posted by Yuri D'Elia <wavexx@thregr.org>.
seconds are too coarse for what we intend. technically, centisecs would
be sufficient (and more honest, given that we prefer coarse timers,
which have only tick precision), but that's a somewhat untypical unit.
in the spirit of being liberal about what we accept.
this completely re-structures the header processing loop, with the nice
side effect of eliminating the gotos.

... instead of reporting conversion errors directly in copy_msg_convert().
this makes it easier to autotest properly.
this reverts bc15e571 in spirit, sidestepping the problem it tried to
solve instead.
don't print the status, as the user doesn't really care whether it's
NO or BAD. more importantly, "NO LOGIN failed" is a rather misleading
thing to report.
replace the "DOM-like" model with a "streaming" model, i.e., the tokens
are now immediately processed by stateful callbacks as they are found.
this avoids plenty of allocations and copies (though not of the message
contents, yet).
- short literals are now printed even with only -Dn.
this ensures that we see all parts of, for example, LIST responses.
we use xprintf() for that, so we don't mess up the -Dn output in case
the literal contains something unexpected (we don't care with -DN).
- omitted bytes are now indicated.
- missing trailing newlines are now "pretty-printed".
- long literals are now printed in chunks as we receive them. this
makes the output messier, but it's necessary for an upcoming change,
and, on the upside, we'll get better indication when the transfer
gets stuck in the middle of a message.
this introduces a "commit" callback to the xprintf kernel, to avoid
pointlessly assembling a temporary output string prior to printing it.
one could lift the buffer limitations by introducing a "segment"
callback instead, but that would slow down xvasprintf() due to the
higher callback rate, for no good reason.
so far we shifted down the buffered data only when we ran out of space.
however, that may cause chopping up the actual socket read, which is a
bad trade-off with avoiding a moderate-sized memmove. so try to keep
enough space for the anticipated read size.
note that this ignores the zlib path, as that always does full-size
socket reads into z_buf, and saving inflate() calls seems pointless.
- use more appropriate name for socket object
- localize some variable declarations
- denoise the code by using more local variables
- don't pointlessly do stuff when we're failing anyway
technically, we should have been doing that since the beginning, but as
there is IMAP4rev2 now, it might actually matter (in about a decade,
when servers start dropping backwards compat ...).
