- whitespace fixes - don't allow local ipk to clobber existing packages - install local ipk from any of /media/hdd/images/ipk, /media/usb/images/ipk, /media/mmc/images/ipk, /media/cf/images/ipk

Since 201e44b the socketmmi.getSocketStateChangedCallbackList(), is called before eAutoInit performed it's job. Initializing socketmmi on sessionstart solves the crash on early call on socketmmi_get_socket_state_changed_cb_list. Program received signal SIGSEGV, Segmentation fault. PSignal::get (this=0xf8) at python/connections.cpp:25 25 if (!m_list) (gdb) bt #0 PSignal::get (this=0xf8) at python/connections.cpp:25 #1 0x00007fffef658945 in socketmmi_get_socket_state_changed_cb_list (self=<optimized out>) at socket_mmi.cpp:316 ....

This commit fixes a heap-buffer-overflow found using ASAN.
Same issue also seens to occur on readyErrRead, so fix it there as well.
In order to verify that console is not breaking after this commit
a random file was written to stdout using cat.
The file was written to another file and hashes where same on input
file and on output file. That seems enough as a test schenario.
Input file can be created using command: dd if=/dev/urandom of=/tmp/in.dat bs=1 count=1024
def yellow(self):
self.container = eConsoleAppContainer()
self.container.appClosed.append(self.finish)
self.container.stdoutAvail.append(self.write)
self.container.setBufferSize(1024)
catargs = ['/bin/cat', '/tmp/in.dat']
self.container.execute('/bin/cat', *catargs)
def finish(self, retval=None):
self.container.kill()
def write(self, data):
file = open('/tmp/out.dat', 'ab')
file.write(data)
file.close()
The full error from ASAN follows:
