bitbake-layers: fix duplicated help info

There are two "help" lines when run bitbake help under python 2.6.6
(perhaps all python 2.6):

$ bitbake-layers help
[snip]
help
    display general help or help on a specified command
[snip]
help
    display general help or help on a specified command

This is because the cmd.py in python 2.6.6 also has a do_help() function
as our bitbake-layers, and the cmd.Cmd.get_names() doesn't consider the
overload, this has been fixed in python 2.7, use set() to remove the
duplicated would fix the problem.

monitordisk.py: monitor disks based on path

The previous monitor is based on the disk, and one disk only can have
one action, this limits its function, for example we set this in the
current local.conf:

BB_DISKMON_DIRS = "\
    STOPTASKS,${TMPDIR},1G,100K \
    STOPTASKS,${DL_DIR},1G,100K \
    STOPTASKS,${SSTATE_DIR},1G,100K \
    ABORT,${TMPDIR},100M,1K \
    ABORT,${DL_DIR},100M,1K \
    ABORT,${SSTATE_DIR},100GM,1K"

Before:
  * If TMPDIR, DL_DIR and SSTATE_DIR are on the same disk partition,
    only the last line "ABORT,${SSTATE_DIR},100GM,1K" works

  * If TMPDIR, DL_DIR and SSTATE_DIR are on the different disk partitions,
    only the last three lines (ABORT) work.

These are not what we expect, now:
  * We monitor the disk based on the path and action, so all the six lines
    will work no matter whether they are on the same disk partition or
    not.

  * The out put format will be:
    WARNING: The free space of /path/to/directory (device) is running low (XXGB left)

utils.py: fix BB_ENV_WHITELIST

The BB_ENV_WHITELIST doesn't work well and flushes BB_ENV_EXTRAWHITE,
here is an example:

$ export BB_ENV_WHITELIST

$ export BB_NUMBER_THREADS=10 (or other value)

Edit conf/local.conf, change "BB_NUMBER_THREADS =" to "BB_NUMBER_THREADS ?="

$ bitbake -e | grep '^BB_NUMBER_THREADS ='
we will notice that BB_NUMBER_THREADS' value doesn't change, though
BB_NUMBER_THREADS in both BB_ENV_WHITELIST and BB_ENV_EXTRAWHITE.

This is because the "approved" inside the function approved_variables
doesn't include BB_ENV_WHITELIST or BB_ENV_EXTRAWHITE when
BB_ENV_WHITELIST is set (they are incuded by preserved_envvars()), so
the BB_ENV_WHITELIST and BB_ENV_EXTRAWHITE will be removed from the env
in the first call from bin/bitbake, and when it is called again by
cooker.py, their value will be None, then the vars inside them will be
removed from the env.

Add BB_ENV_WHITELIST and BB_ENV_EXTRAWHITE to the "approved" would fix
the problem.

hob: some settings in Hob are not remembered

Some settings in Hob were not saved in Bitbake and they were not displayed
correcty in Hob, because Hob used some other variables with the extension "_HOB".
I have removed this, in order to have a consistency for the variables.
ALso, I called a function to load the extra variables saved in .hob/template_default.hob.

    taskdata: Add gettask_id_fromfnid helper function

    This is like gettask_id but doesn't require translation of fnid -> fn
    first which the function then translates back. This gives a sizeable
    performance improvement since a significant number of lookups are avoided.

* now it fails completely instead of showing which task is missing
