This patch adds support for ALUA MI_REPORT_TARGET_PGS extended header format defined within SPC-4. It changes target core ALUA emulation logic within target_emulate_report_target_port_groups() to support both the extended and original length only header formats. It includes adding a new 'implict_trans_secs' attribute for each ALUA target port group to control the value returned to the application client for an recommended implict translation timeout in seconds. By default this value is currently set to zero, and limited up to 255 by virtue of using a single byte in the extended header format. This value is used by target_emulate_report_target_port_groups() within the extended header logic to set IMPLICIT TRANSITION TIME as defined by spc4r30.
