amf: validate env variable format set in comptype/comp objects [#2409]

Valid environment variable should have the format 'var=value'.

AMF currently does not validate this format during CREATE CCBs
for comptype and comp objects (MODIFY allowed for comp after #2255)
related to saAmfxxxCmdEnv attribute.
Besides, the existing validation in avnd_comp_clc_cmd_execute()
is not good enough. This results in invalid env variables getting
printed with weird output.

Also, there is currently no check for duplicate env variables set
in both comptype and comp, so they get printed twice in trace.

This ticket fixes the above issues:
- Validate env variable format during comp[type] CREATE, MODIFY CCBs.
- Overwrite env variable set in comptype if it is also set in comp.

Testing Commands:
-----------------
1) Create SaAmfCompType/SaAmfComp objects with invalid env variable format
in attributes saAmfCtDefCmdEnv/saAmfCompCmdEnv. (e.g 'var = value', 
'var==value')
2) Modify attribute saAmfCompCmdEnv of SaAmfComp object with invalid env
variable format.


Testing, Expected Results:
--------------------------
AMFD will reject CREATE/MODIFY CCBs with invalid env variable format.


Conditions of Submission:
-------------------------
Ack from reviewers of after 2 weeks.

-------------------
[Submitters: make sure that your review doesn't trigger any checkmarks!]


Your checkin has not passed review because (see checked entries):

    that need proper data filled in.

___ You have failed to nominate the proper persons for review and push.

___ Your patches do not have proper short+long header

___ You have grammar/spelling in your header that is unacceptable.

___ You have exceeded a sensible line length in your headers/comments/text.

___ You have failed to put in a proper Trac Ticket # into your commits.

___ You have incorrectly put/left internal data in your comments/files
    (i.e. internal bug tracking tool IDs, product names etc)

___ You have not given any evidence of testing beyond basic build tests.
    Demonstrate some level of runtime or other sanity testing.

___ You have ^M present in some of your files. These have to be removed.

___ You have needlessly changed whitespace or added whitespace crimes
    like trailing spaces, or spaces before tabs.

___ You have mixed real technical changes with whitespace and other
    cosmetic code cleanup changes. These have to be separate commits.

___ You need to refactor your submission into logical chunks; there is
    too much content into a single commit.

___ You have extraneous garbage in your review (merge commits etc)

___ You have giant attachments which should never have been sent;
    Instead you should place your content in a public tree to be pulled.

___ You have too many commits attached to an e-mail; resend as threaded
    commits, or place in a public tree for a pull.

___ You have resent this content multiple times without a clear indication
    of what has changed between each re-send.

___ You have failed to adequately and individually address all of the
    comments and change requests that were proposed in the initial review.

___ You have a misconfigured ~/.gitconfig file (i.e. user.name, user.email etc)

___ Your computer have a badly configured date and time; confusing the
    the threaded patch review.

___ Your changes affect IPC mechanism, and you don't present any results
    for in-service upgradability test.

___ Your changes affect user manual and documentation, your patch series
    do not contain the patch that updates the Doxygen manual.
