This commit tries to keep code logic the same while changing underlying
code to use unified callbacks.
* Add llt_foreach_entry method to traverse all entries in given llt
* Add llt_dump_entry method to export particular lle entry in sysctl/rtsock
format (code is not indented properly to minimize diff). Will be fixed
in the next commits.
* Add llt_link_entry/llt_unlink_entry methods to link/unlink particular lle.
* Add llt_fill_sa_entry method to export address in the lle to sockaddr
format.
* Add llt_hash method to use in generic hash table support code.
* Add llt_free_entry method which is used in llt_prefix_free code.
* Prepare for fine-grained locking by separating lle unlink and deletion in
lltable_free() and lltable_prefix_free().
* Provide lltable_get<ifp|af>() functions to reduce direct 'struct lltable'
access by external callers.
* Remove @llt agrument from lle_free() lle callback since it was unused.
* Temporarily add L3_CADDR() macro for 'const' sockaddr typecasting.
* Switch to per-af hashing code.
* Rename LLE_FREE_LOCKED() callback from in[6]_lltable_free() to
in_[6]lltable_destroy() to avoid clashing with llt_free_entry() method.
Update description from these functions.
* Use unified lltable_free_entry() function instead of per-af one.

Currently, every buffer cached in the L2ARC is accompanied by a 240-byte
header in memory, leading to very high memory consumption when using very
large cache devices. These changes significantly reduce this overhead.
Currently:
L1-only header = 176 bytes
L1 + L2 or L2-only header = 176 bytes + 32 byte checksum + 32 byte l2hdr
= 240 bytes
Memory-optimized:
L1-only header = 176 bytes
L1 + L2 header = 176 bytes + 32 byte checksum = 208 bytes
L2-only header = 96 bytes + 32 byte checksum = 128 bytes
So overall:
Trunk Optimized
+-----------------+
L1-only | 176 B | 176 B | (same)
+-----------------+
L1 & L2 | 240 B | 208 B | (saved 32 bytes)
+-----------------+
L2-only | 240 B | 128 B | (saved 116 bytes)
+-----------------+
For an average blocksize of 8KB, this means that for the L2ARC, the ratio
of metadata to data has gone down from about 2.92% to 1.56%. For a
'storage optimized' EC2 instance with 1600GB of SSD and 60GB of RAM, this
means that we expect a completely full L2ARC to use (1600 GB * 0.0156) /
60GB = 41% of the available memory, down from 78%.
characters use the defined constant so that in case of change this
would not break.
