Recover the least-recently-allocated cache primitive from the January
object: 0x3c-byte lra_cache ('lrac' signature, name, size,
base_address, malloced flag, last_block, update/delete procs) and
0x10-byte in-buffer lra_block headers ('Ablh' signature with locked
and deleted flag bits, user address pointer, size, forward chain).
Seven of fourteen functions are proven exact: lra_full, lra_new,
lra_dispose, lra_flush, the default update/delete callbacks and the
block-invalidate helper code_0010ba10 with its ESI/ECX register
convention. The remaining seven are byte-complete reconstructions
blocked on a single interlocked register-allocation choice (cache in
EBX versus EDI) shared by the verify helpers and their callers, plus
one callee-saved-count difference in lra_allocate.
