Add Coverity Scan analysis

[mayeut]

GitHub, travis-ci & Coverity Scan work well together.
OpenJPEG should make full use of this by adding Coverity Scan analysis to find defect as soon as possible.

coverity just fixed sth that prevented settings to be updated to link to the new github repo. Integration with github and travis should work now.

[detonin]

Btw, they recommend to create a coverity branch where we merge when we want to trigger a scan, rather than triggering a scan for each and every commit.

@detonin,

It seems that the link between coverity & GitHub is not done.
Project Settings in Coverity shows that a link should be done.
I can't do this as I have no Admin access to the repo (I guess, the error is cryptic when I click submit). Could you do that please ?

[detonin]

@mayeut ,
Yes I did it too but nothing seems to happen. I get the following error:
Failed to link project. Name contains invalid characters.

I'll dig into this or contact the support again if i don't solve this myself.

[detonin]

I changed the name in coverity to fix previous issue but now there is no github integration link button anymore. I'll contact the support

[detonin]

waiting for coverity support to answer

[detonin]

No answer from support.
I've re-created a project directly linked with github.
Configuring travis-ci should work now with instructions found in "Configure Travis-CI" tab, on the page reached when clicking "submit a build".

What cmake options shall be enabled ?

• BUILD_CODEC
• BUILD_THIRDPARTY

[detonin]

I would recommend these two options only for now.
MJ2, JPIP, and JPWL are (still) obsolete in master and I did not yet take a decision on the future of these features. Comments welcome btw.

[mayeut]

This is done for some time now.

@detonin, @mayeut, I suggest updating https://scan.coverity.com/projects/uclouvain-openjpeg. There were a lot of code changes since the last version which is covered by Coverity scan (September 2016).
