2f91e22371 fix LOGIN in SASL builds
if AuthMechs includes more than just LOGIN and the server announces any
AUTH= mechanism, we try SASL. but that can still fail to find any
suitable authentication mechanism, and we must not error out in that
case if we are supposed to fall back to LOGIN.

bc51d0206a fix LOGIN in non-SASL builds
specifically, if AuthMechs included more than just LOGIN (which would be
the case for '*') and the server announced any AUTH= mechanism, we'd
immediately error out upon seeing it, thus failing to actually try
LOGIN.

815822d81c don't arbitrarily limit UIDs to a billion
the number was chosen to make queries more comprehensible when the
server sends no UIDNEXT, but it appears that such insanely large UIDs
actually show up in the wild. so send 32-bit INT_MAX instead.

note that this is again making an assumption: that no server uses
unsigned ints for UIDs. but we can't sent UINT_MAX, as that would break
with servers which use signed ints. also, *we* use signed ints (which is
actually a clear violation of the spec).

it would be possible to special-case the range [1,inf] to 1:*, thus
entirely removing arbitrary limits. however, when the range doesn't
start at 1, we may actually get a single message instead of none due to
the imap uid range limits being unordered. this gets really nasty when
we need to issue multiple queries, as we may list the same message
twice.

a reliable way around this would be issuing a separate query to find the
actual value of UID '*', to make up for the server not sending UIDNEXT
in the first place. this would obviously imply an additional round-trip
per mailbox ...

e054c575ea fix CertificateFile docs & samples
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.

cda596d530 remove legacy (bsd-style) locking
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 ...

8979ebbdf2 tolerate case changes in X-TUID header name
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.

02af3f4c73 ensure direct exit after calling back
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.

6c08f568d0 fix socket_write() recursion
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.

b85153f8eb make skipping of failed stores more thorough
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.

98bd2b115d make it possible to nest maildir Path under Inbox
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.

8dc776c528 fix SASL, take 2
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 old meaning of -V[V] was moved to -D{n|N}, as these are really

- 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.
