[dts] [PATCH 0/4] Support debug mode in DTS

[Yong Liu]

From: Marvin Liu <yong.liu at intel.com>

This patch support debug mode in dts. In debug mode, user can directly take 
operation on ssh connections or call python debug interpreter.

DTS can enter debug mode by input keyboard interrupt "ctrl+c" at anytime.
Then user can take ownership of session by command like "connect("dut")".
The connected session can be listed by command "list()".
After debug done, can return from ssh connection to debug mode by command 
"ctrl+]".
Debug mode can also return to normal mode by command "quit()".

There's one bug in pexpect module need manually fixed.
/usr/lib/python2.7/site-packages/pexpect/__init__.py should changed as below.
        #  if err.errno == errno.EINTR:
        if err[0] == errno.EINTR:

Marvin Liu (4):
  framework: add debugger module for enable debug in the running process
  framework: maintain connected session list and disable debug mode in
    send_expect
  framework: change alt session name for easy to distinguish
  framework: enlarge hugepage number for dpdk2.0 request more memory
