We optimize HTTP requests to Review Board by prioritizing repositories
based on name. Previously this was done using strict comparison of name
returned by Review Board to name returned by cleartool. This is no good
when supporting users on Windows and Unix both. They are different, as
shown here:

    W:\srcSHARE>cleartool describe -short vob:.
    \srcSHARE

And when the VOB is mounted to /vobs in Unix:

    [/vobs/srcSHARE]$ cleartool describe -short vob:.
    /vobs/srcSHARE

Now we compare the name of the returned repository with each part of
the VOBs tag returned by cleartool. Subsequently, Review Board server
administrators can set repository names for individual VOBs and can
expect it to match for users regardless of platform. `srcSHARE` works
in the example above.

I posted a review to an internally-hosted Review Board instance from a

VOB with the name srcSHARE on both Linux and Windows. The repository

in Review Board has the name srcSHARE.
In the debug output it is clear that the number of repositories queried

is reduced. In our specific case because the Review Board server is

hosted very far away, this represents a time savings of a few minutes

for each review posted.
