c0d1c122c3 ISCSI-LS : Change from popt to the slightly less portable getopt_long 
win32 and amiga/aros does not have getopt_long() so we will need a
replacement for the platforms where getopt_long() is missing.

6884b6eb75 LD_ISCSI add write 
the write command is limited in the sense that file offset and
count bytes must be multiple of the targets blocksize. for most
copy/dd etc. operations this is sufficient to work.

50e7c682bb Add a logging subsystem and change all DPRINTF to ISCSI_LOG 
Add a mechanism where we can set a logging subsystem that libiscsi can use.
Create an example 'log to stderr' that utilities can use for convenience.

afc963c312 LD_ISCSI: cache last result of get_lba_status 
get_lba_status returns provisioning for a range of blocks starting
from given lba. Especially for sequential reads its likely that
the next block read is already covered by the last result.

In case there is write support added to ld_iscsi there needs
to be an invalidation code for the cache.

bfac1f85a3 LD_SCSI: Introduce get_lba_status in read() 
For large continous reads I may be benifical to check if the blocks
that are going to be read are allocated. If they are not allocated
they do not need to be read which massivly speeds up the read.

This behaviour is optional and can be turned on with environment
variable LD_ISCSI_GET_LBA_STATUS=1

d5f646099d READ10/WRITE10: Change these functions to sue the same signatures as the other READ/WRITE 
Harmonize the signatures for READ10/WRITE10 to match the ones for READ12/16 and WRITE12/16

This breaks the API/ABI so this forces the next version of the library to bump the major version to 2.0

35821830d6 LD_ISCSI.SO LD_PRELOAD hack 
ld_iscsi.so is a small LD_PRELOAD hack that can be used to make normal
unix utilities such as 'stat' and 'cat' become iSCSI 'aware' and fake
handling an iSCSI URL as a normal read-only file.

See README for examples.
