From #92, when rebooting a platform the internal connection state becomes
different from `_connected_as_root`, now clears the state upon device reboot or
reset.
Gem5SimulationPlatfrom was not acceping base Platform's parameters, such
as core_names, making it impossible to configure them on construction.
This is rectified in this commit.
When rebooting a platform the internal connection state becomes
different from _connected_as_root, which was set before reboot.
Add the possibility to force adb root if you've rebooted or know
to have done something that would result in the platform having
a different connection state than the one of _connected_as_root.

Commit 28891a82 made it easier to debug issues during walk_modules by
attaching the specific name of the module being loaded to the exception.
However, the error may not originite in the imported module, but one of
the modules that module itself is importing.
To further facilitate debugging, exc_info (which contains the traceback)
for the orginal ImportError is now also attached to the raised
HostError.
This regex currently matches the `rc` group against the added-patches-count,
e.g. "00005" in "4.4.41-00005-g17b74bafccbe-dirty" and "59" in
"4.4.0-59-generic". Fix this by requiring "rc" in the match.
This adds a regexp to better parse all the kernel version numbers as well
as additional (optional) fields like SHA1 and RC.
The regexp has been made generic enough to match these examples:
4.9.0-rc6-00202-g3a60597

This adds a couple of commodity ADB commands to reboot in bootloader
mode and to restart ADB in root mode.

ADB commands always expect a device ID as first parameter, here
unfortunately we need to pass it as an optional one to avoid breaking
existing clients.

This parameter is used by the other connection classes and as of
21f40035d7 ("gem5: Small tweaks in target to allow gem5 simulations") is
passed by to the connection class constructor via expansion of
Target.connection_settings (see Target.get_connection)
Previously, if an error had occured while attempting to load a module
during walk_modules, it was propagated to the loading code. This
meant that walk_modules could, in theory, raise any exception at all,
and that it was not always possible to tell exactly where the exception
originated.
Now, all encounted errors are re-raised as HostError, which preserves
the original exception in an attribute and sets "modpath" attribute to
point to the module that originated it.
Moved TimeoutError from devlib.util.misc to devlib.exception. It was
previously defined in misc because it needed to be there when the code
was part of WA in order to prevent an import cycle. This is not
necessary in devlib, so it is moved to be with the other exception
definitions.
The m5 binary allows the user to interact with gem5 simulation (e.g. reset stats).

This commit adds a gem5 simulation platform. The platform is responsible for starting the gem5 simulation.

This is the first in a series of commits to allow for the use of gem5 as a target in devlib.
The interaction with the gem5 simulation is done by the Gem5Connection, a type of TelnetConnection.
There are two types of Gem5Connections (Linux and Android) as they differ slightly in the implementation
of some methods. Other types of connections have only been changed to make them uniform (e.g. arguments for init method)

Add exit code, command, and output to TargetError exception message when execute
fails. This brings LocalConnection into line with AdbConnection and
SshConnection.
killall() is implemented by discovering all PIDs who's name matches the
specified process, and then sending individual kills for each PID. If a
PID no longer exists by the time the kill is sent (e.g. if it was a
child of one of the previously killed PIDs), this will result in a
TargetError, which for the purposes of killall() should be ignored.
On older combinations of ADB/Android versions, the adb host command always
exits with 0 if it was able to run the command on the target, even if the
command failed (https://code.google.com/p/android/issues/detail?id=3254).
When we need the target's exit code (check_exit_code=True), we currently work
around this behaviour by echoing the target's exit code after the command and
parsing it out of the output.
The ADB behaviour is now "fixed" on newer versions with newer Androids (It's not
clear which versions these are and it appears that different builds of ADB with
the same version number differ in this respect). For those version combinations
adb_shell will currently raise a CalledProcessError when check_exit_code=False
and the target command fails.
So lets now use the "echo $?" trick whether or not we need the exit code.
Fixes https://github.com/ARM-software/devlib/issues/85
The current run_into method attempts to execute:
<...>/shutils CGMOUNT=<...> cgroups_run_into <...>
Which should instead be:
CGMOUNT=<...> <...>/shutils cgroups_run_into <...>
So just use cgroups_run_into_cmd to generate the command, then execute that.
When ANDROID_HOME is defined, ANDROID_HOME/platform-tools was appended
to the PATH in the environment of the Python interpreter. That meant
that if an adb binary was in PATH, it would be picked in preference to
the one under ANDROID_HOME. This is now reversed so that ANDROID_HOME
takes precedence.
Perviously, a parameter passed into SshConnection controlled whether the
connection was established over SSH or Telnet. Now, there is a separate
class for Telnet connections.
