Forging of BIO_METHOD may be the cause of the stack overflow as the
internal structure in openssl changed so the methods get assigned to
wrong pointer.
Kudos Cyril to notice newer openssl internal struct had one new pointer
inserted as second member
Caused by unneeded pointer usages + not enough careful IPv6 porting
I haven't managed to reproduce the crash nor to test the fix due it
happening only when UDP relayed connection happens (apparently never on
my nodes.
I have managed to discover where the bug comes from thanks to multiple
user reports, specially to Ilario report which documented 3 crashes
happening on 0.6.4 with complete log.

This function is part of the public API so it must be safe to call with
any input, before this commit if would crash if feeded with a broken or
empty certificate radix string.
Order of serialization doesn't matter ATM as we use those only for
JSON API.
Those classes should be rewritten anyway with proper naming of the
memebers and using std::uintptr_t instead of void* and rstime_t for
timestamps
Now the possible id of the cannel/post is returned and channel/post is
indexed on creation without having to wait for gxsutil scan to happen
Note that the id is correct in normal usage, but if one try to overload
the API per eventually get the id of another channel/post with same data
but created by a different call, it is not dangerous so one trying to
overload the API is just getting a possibly wrong but equivalent
channel/post id returned.
If the member was not present in the JSON it was zeroed while it should
be left untouched in that case.
This was discovered because in JSON API defualt argument value for
methods wasn't onored for t_RsFlags32 arguments.
