If "capacity" LU option is set, ramdisk backend now implements featured
thin provisioned disk, storing data in malloc(9) allocated memory blocks
of pblocksize bytes (default PAGE_SIZE or 4KB). Additionally ~0.2% of LU
size is used for indirection tree (bigger pblocksize reduce the overhead).
Backend supports all unmap and anchor operations. If configured capacity
is overflowed, proper error conditions are reported.
If "capacity" LU option is not set, the backend operates mostly the same
as before without allocating real storage: writes go to nowhere, reads
return zeroes, reporting that all LBAs are unmapped.
This backend is still mostly oriented on testing and benchmarking (it is
still a volatile RAM disk), but now it should allow to run real FS tests,
not only simple dumb dd.

Replace archaic "busses" with modern form "buses."
Intentionally excluded:
* Old/random drivers I didn't recognize
* Old hardware in general
* Use of "busses" in code as identifiers

Connection parameters should remain at defaults until negotiated.
While there, remove sythetic limits, applied if kernel provided none.
iscsid has no own limitations, no configuration and no any idea what
values are good. Assume kernel knows what it requests.
If initiator does not negotiate some parameter, it expects one to get
default value, not some unknown remote hardware limit. On the side side,
if some parameter is negotiated, its default value from RFC should not
be used for anything.
- Only #include tcpd.h when LIBWRAP is true to avoid header include errors
- Only define whichaf when LIBWRAP is true to avoid -Wunused warning and
to avoid issues with structs being defined that should only be defined
when tcpd.h is included.
