- wrap flow-controlled statements that contain blocks into blocks
themselves
- wrap bodies of do-while()s into blocks
- use braces on 'else' symmetrically (this obviously has a cascading
effect, so this patch touches lots of lines)
- attach braces
unavoidably, the rules are sometimes broken around #ifdef-ery.
instead of specifying the mailboxes and sync state verbatim, use a
format which deals only with "subjects" (but no UIDs), and specifies the
whole state for each subject on a single line (exceptions prove the
rule).
the dumpers don't try to re-create the abstraction, as that's deemed
to be an unreasonable effort.
while rewriting most of the test data anyway, move it to the bottom of
the file, which is a more natural location for it.
don't abort the comparison if continuing makes sense, and try to be more
specific about the problems.
we give up if messages are excessive/missing or the subject is wrong,
as that touches upon the rather complex problem of diff optimization.
this avoids the ugly and error-prone repeated reading of the state
after a failure.
cmpbox() had to be made non-destructive on the box state.
readchan() had to be created.
parse the test data into hierarchical structures instead of using it in
its raw form. this is semantically cleaner and allows us to change the
input format more easily.
it doesn't really add any value when resuming after an interruption, as
incomplete propagations are perfectly expected, and are recovered from.
but it does make sense in the non-UIDPLUS path, where not finding just
stored messages indicates a problem.
so move the reporting from match_tuids() to msgs_found_new(), and remove
a redundant warning from the latter.

while at it, add/fix some licenses/copyrights/comments:
- it makes no sense to have a GPL exception in scripts
- ted did not contribute to the man page
- tst_timers is not part of the mbsync executable
- explicitly put the build system under GPL and add copyrights
manual:
- explain what "rename on move" really means
- reword "remote" to "opposite" to make it less confusing
(possibly renaming TrashRemoteNew left as an exercise for later)
- mention example mbsyncrc
- consistently capitalize Store/Channel/Group where they refer to the
respective configuration entities
- emphasize that SyncState may need a trailing slash (as we do for Path)
- fix missing mention of global usage/default for some options
example mbsyncrc:
- add big fat note that empty lines matter
- stop demoing deprecated options
- point out that CertificateFile is optional

the messages are trashed in mailbox (and thus UID) order, and in
practice we expect the operations to complete in order. however, if
older messages need to be trashed after a journal replay, and we get
interrupted again, the next replay would produce an unsorted array,
and thus break the binary search.

there isn't really a reason for that; DEBUG_CRASH is quite unlike the
other DEBUG_ flags.
note that the DEBUG_*_ALL flags are not checked, because they always
come with their corresponding less verbose flag anyway.
copy-pasto; it certainly wasn't meant to respond to --debug-sync.
the problem was barely noticeable, as the maildir driver's only debugs
are in the rarely triggered rescan path, apart from the flags usually
being used en bloc anyway.

in certain configurations, under very unlikely conditions (which are
practically impossible to control remotely), we'd overflow ranges[].
in a typical gcc build, the values (which are also practically
impossible to control remotely) would be written at the end of buf[],
which would be rather harmless, as only a tiny part of buf is used
subsequently. so i'm not classifying this as a security issue.
amends 77acc268.
the input isn't necessarily null-terminated (it currently is for imap,
but not for maildir), so if the message ended somewhere within the
header field name, we'd read beyond its end, which theoretically could
cause a crash. no other adverse effects could result, as we'd stop
processing such a broken message right afterwards.
