42ccddeff3 Add read_buffer and write_buffer functions. 
Introduce functions for proper I/O handling. These functions
are able to deal with interrupts and partial I/O.

0435fbf2e5 Avoid write with zero size. 
This can happen if write buffer size is smaller than underlying
block size and initial buffer is misaligned.

Also use size_t for buffer length variables.

65f975655c New device access backend. 
Allocate loop device late (only when real block device needed).
Rework underlying device/file access functions.
Move all device (and ioctl) access to utils_device.c.

Allows using file where appropriate without allocation loop device.

otherwise use topology values.

93796f4036 ... and previous reintroduce it as debug message. 
(The problem is when repeated passphrase input is tried on pipe,
it should not show "error reading passphrase", because it fails
for the second reading attepmt anyway but should retain
error message saying "no key with this passpharase...")
