clang defaults to c99 so remove inline statements
(http://clang.llvm.org/compatibility.html#inline ) on functions shared
across different translation units.
clang's linker doesn't like major numbers over 255 so change how SOREL
is generated in Makefile.am.
Previously COMPAREANDWRITE was only sending verify instance data which
can cause targets to generate COMMAND ABORTED/NOT ENOUGH UNSOLICITED
DATA errors due to the buffer being obviously too small to contain
verify AND write instance data.
The buffer size check has been modified and compareandwrite tests
updated to pass a larger buffer with interesting write instance data.
scsi_set_uint64 should just use scsi_set_uint32, similar to
what scsi_get_uint64 does. This avoids problems on architectures
where "uint32_t" requires more alignment than "char", e.g. ARM.

Casting unsigned char * pointers to uint32_t * may cause wrong
results if the pointers are not correctly aligned. Instead,
build up the big-endian values from each byte with multiple
dereferences of the original pointer.

The maximum number of blocks that can be transferred at once via a READ6
command is 256 instead of 265.

The code that verifies the pr_type response must compare only the
lower four bits of byte 21 of the response ("TYPE") and must ignore
the upper four bits ("SCOPE").

If no reservation is held a SCSI target sends a response that is eight
bytes long while scsi-lowlevel.c fills in the first twelve bytes of a
data structure for which only eight bytes are allocated. Fix this buffer
overflow by always allocating a full
scsi_persistent_reserve_in_read_reservation structure.

Add a simple test that it works or is not implemented.
Add a RCTD test to verify that with this flag clear we get command descriptors without CTDP set and with it set we get command descriptors with CTDP set and a timeout descriptor
This patch adds support for read/writev to directly read and write
from/to iovectors. Before this patch on read and write from/to socket
the operation was limited by the iovec boundaries. If there is enough
data in the buffer or enough buffer space available its now possible
to transfer the whole data in one atomic operaion.
