the mbsync manual says explicitly that the system's default certificate
store should *not* be specified.
however, the isync manual talked about CA certificates, which is (and
always was) exactly wrong.
also adjust both .sample rc files.
flock() may be implemented via fcntl(), which may cause the process to
deadlock itself when trying to apply both types of locks. this is the
case even on linux when the file lives on NFS.
it's unlikely that anything except mbsync would try to access the
.uidvalidity files anyway, so there is no point in trying to be
compatible with anything else ...

it is legal for an email system to simply change the case of rfc2822
headers, and at least one imap server apparently does just that.
this would lead to us not finding our own header, which is obviously not
helpful.

recycling server connections skips everything up to setting up the
prefix (Path/NAMESPACE). "everything" should obviously include enabling
compression, as that must be done at most once per connection.
any structures may be invalid after callback invocation.
this has the side effect that the socket write callback now returns
void, like all other callbacks do.
the synchronous writing to the socket would have typically invoked the
write callback, which would flush further commands, thus recursing.
we take the easy way out and make it fully asynchronous, i.e., no data
is sent before (re-)entering the event loop.
this also has the effect that socket_write() cannot fail any more, and
any errors will be reported asynchronously. this is consistent with
socket_read(), and produces cleaner code.
this introduces a marginal performance regression: the maildir driver is
synchronous, so all messages (which fit into memory) will be read before
any data is sent. this is not considered relevant.
in the case of imap stores, the failure is bound to the server config,
not just the store config.
that means that the storage of the failure state needs to be private to
the driver, accessible only through a function.
simply make the code symmetrical to the inverse case.
note that the result will be sort of awkward, as the folders under Path
(and thus the subfolders of Inbox) don't start with a dot, while the
subfolders of these folders do. this needs to be addressed separately.
when we run into Inbox while listing Path, check whether Inbox is being
listed anyway, and just skip it if so, instead of listing it right away
and resetting LIST_INBOX (and thus having a calling order dependency).
USER (the authorization identity) specifies whom to act for.
AUTHNAME (the authentication identity) specifies who is acting (and
thus whose PASS is being used).
USER is derived from AUTHNAME if omitted, but apparently the
GSS-API module automatically adds the REALM, which is not helpful.
it appears to be common to set both USER and AUTHNAME to the same value,
so let's just do it as well.

the PassCmd will be typically non-interactive (or it will use a gui
password agent), so starting a new line just makes the progress counter
uglier. so make it configurable and default to no line break.
- the old meaning of -V[V] was moved to -D{n|N}, as these are really
debugging options.
- don't print the info messages by default; this can be re-enabled with
the -V switch, and is implied by most debug options (it was really
kind of stupid that verbose/debug operation disabled these).
- the sync algo/state debugging can be separately enabled with -Ds now.
... instead of determining them on the fly, because
- it enables early display of totals (to be used soon)
- it enables re-use of the data (to be used at some point)
- the code is less cryptic
note that we leak the data created in main(), consistently with other
configuration-related data.
instead of creating three lists of mailboxes (common, master, slave)
and deriving the mailbox presence from the list being processed, create
a single joined list which contains the presence information.
additionally, the list is sorted alphabetically (with INBOX first),
which is neater.
it helps if the code actually does what the comment above it claims.
clarify it a bit, so i don't get stupid ideas again.
This reverts commit cf6a7b4d18.
