tcn_ssl_ctxt_t alignment to avoid padding
tcn_ssl_ctxt_t alignment to avoid padding

Motivation:
tcn_ssl_ctxt_t is not properly aligned which may result in increased memory or additional padding inserted. Relying on the compiler optimization can be fragile and lead to inconsistencies between compilers.

Modifications:
- Align internals of tcn_ssl_ctxt_t to be grouped in 64 byte chunks.

Result:
More proper memory alignment of the tcn_ssl_ctxt_t structure.
