e95291f019 ipsec: support multi-segment packets
Add support for packets that consist of multiple segments.
Take into account that trailer bytes (padding, ESP tail, ICV)
can spawn across multiple segments.

6015e6a133 ipsec: move inbound and outbound code
sa.c becomes too big, so decided to split it into 3 chunks:
 - sa.c - control path related functions (init/fini, etc.)
 - esp_inb.c - ESP inbound packet processing
 - esp_outb.c - ESP outbound packet processing

Plus few changes in internal function names to follow the same
code convention.
No functional changes introduced.

security API to provide application with transparent IPsec processing API.
That initial commit provides some base API to manage
IPsec Security Association (SA) object.
