'RELENG_4_1_0_RELEASE'.

This commit was manufactured to restore the state of the 4.1-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Add 8 bits of volatile mailbox busy mask- this will be the bitmask
of output mailbox values we want to get back out of the chip once
a mailbox command is done. Add storage for the maximum number of
output mailbox registers to the softc.  Set ISP_MAX_LUNS to be off
of new isp_maxluns tag in softc.  Change our 'fabdev' tag to
'loggedin'.  Increase size (and add defines for) topology storage.

Roll minor version numbers.

instead of FC-AL (2200 only).

of target mode related enums.

Role the core version minor number. Change the arguments to the dma
setup function to use a u_int16_t for the output request loop pointer
(truly amazing that this hasn't blown up in anyones face so far). Do
some shuffling around of some items.

the result queue length is never less than 64. Move (ick) temp port
database used for post-LIP merging off the kernel stack and put it
into the softc. Remove some target mode stuff which will come back
later in a different file. Change how the list of outstanding commands
are stored (now allocated at mailbox setup time to be just enough for
the max for a specific HBA which can vary). Keep a rotating seed of
the last index for this in the softc. Increase the count of active
commands from 10 to 16 bits.
