This is a refactoring before further modifications. Should
not have any semantic changes.

Items:
 - file.readlines() is not necessary, file is line-iterable
 - use "cwd" named parameter in subprocess.call() instead of explicit "cd"
 - auto close using scope manager: "with xxx as yyy:"
 - os.path.exists() instead of os.access(mmod_path, os.F_OK) == False
 - extract paths containing ".." to variables

Duration analysis is based on trace pairs which follow the convention
in which function entry generates trace named X and ends with either
trace X_ret or X_err. Traces which do not have an accompanying return
tracepoint are ignored.

  osv trace summary

      Prints execution time statistics for traces

  osv trace duration {function}

      Prints timed traces sorted by duration in descending order.

to always call run.py with this option enabled.
Thus, we're doing this change just for the build run (Suggested by Nadav Har'El).

Some older version of qemu-nbd cuases error exit with nbd_client.py.
(Look at: https://groups.google.com/d/msg/osv-dev/EW5BtNFNfzs/I33BeFXg2f0J

)
This is because nbd_client.py is sending FLUSH command unconditionally, but it's extended feature, nbd client should check nbd server has the capability to accept FLUSH.
nbd server sends capability flags on negotiation stage, it sends HAS_FLAGS(0x1) and SEND_FLUSH(0x4) when server supports FLUSH.

This patch adds these capability check, and skips to send FLUSH if server doesn't support it.

The idea of the patch is basically described in prevoius post:

https://groups.google.com/d/msg/osv-dev/RL2S3AL9TNE/l4XZJo3-lI0J

Whis this patch, you will be able to install OSv apps into disk image on
"make all" stage.

These apps does not require to exist in OSv repository, you can install
apps which is on any git repository or svn repository, or on local
directory.

You'll need to write a config file to add apps, format of the file is
JSON.

Here's a sample of the file:
{
   "modules":[
      {
	 "name":"osv-mruby",
         "type":"git",
         "path":"https://github.com/syuu1228/osv-mruby.git",
         "branch":"master"
      }
   ]
}

If you add "module" on config file, make all calls script/module.py.

This scripts perform "git clone" to fetch repository to $(out)/module,
and invoke "make module" on each module.

"make module" should outputs bootfs.manifest/usr.manifest on module
directory, the script merge bootfs.manifest.skel/usr.manifest.skel and
module local manifests to single file
$(out)/bootfs.manifest/$(out)/usr.manifest.

Here's app Makefile example:

  https://github.com/syuu1228/osv-mruby/blob/master/Makefile



It have "module" target, and the target builds all binaries and
generates *.manifest.

This fixes 'osv info threads' command.

when $rsp holds 0xffffc0003fdf6fc8, ulong() for gdb.Value representing
it returns 18446673706036981704. This is out of int range. This
causes that thread_context.__exit__() throws "Numeric constant too
large" exception from

  set $rbp = 18446673706036981704

The fix removes the additional conversion as it seems to be
unnecessary. The gdb.Value should format itself properly.

The script supports 3 modes of operation:
  - public release (default) for official releases
  - private release - for internal testing
  - development instance - for development

Public release means AMI created public (visible to everyone) and replicated
over all existing Amazon regions.

Private release means AMI created private (visible to releaser's account only) and
not replicated over regions.

Development instance means no AMI created, script stops after instance creation.

The script's help screen (--help command line parameter) provides detailed information
about script interface, dependencies and configurations required.

It's interesting to note that each public release made by this script costs about 20 USD
mainly because of AMI replication over Amazon regions
