Jansson 2.7 requirement in 2.5.9 breaks RHEL/CentOS 6

[ellie timoney]

Hi Sebastian,

Thanks for the report.  I've just pushed commit 8a41e54 to the
cyrus-imapd-2.5 branch, which is a back port of master's jansson
backwards-compatibility layer:

https://github.com/cyrusimap/cyrus-imapd/commit/8a41e5417168b8df53bd7c0cf2071befeebca32b

I've tested this with jansson-2.3 and it looks good, so newer versions
should be fine too.  If you're able to, I'd appreciate if you could try
this out and confirm whether it works for your setup.

Cheers,

ellie
